Leyden Energy Launches Three-year Lithium Ion Batteries

Welcome to a Laptop Battery specialist
of the Asus Laptop Battery   First post by: www.itsbattery.com


How many of you have run into the overheating, premature death of a laptop battery? I know we have. Then you may like the news of a three year battery – guaranteed. Last week Leyden Energy launched its next-generation replacement lithium-ion batteries for laptops. The batteries such as Asus A42-A3 Battery, Asus A8F Battery, Asus F3T Battery, Asus F3Sc Battery, Asus F3Sv Battery, Asus 90-NI11B1000 Battery, Asus 90-NIA1B1000 Battery, Asus 90-NF51B1000 Battery, Asus 70-NF51B1000 Battery, Asus A32-A8 Battery, Asus Z99J Battery, Asus Z99H Battery won’t lose their full charge for at least three years, and will come with a three-year warranty to boot. Leyden has a deal to sell their batteries online with Dr. Battery, a Canadian-based supplier of replacement batteries for tablets, laptops and other electronic devices. The batteries should be available for purchase in a couple of weeks.


It’s pretty frustrating when a laptop loses the ability to fully charge and barely provides you with a couple hours of battery life. For most laptops, the battery will start losing its ability to fully charge after about a year and a half. Dell estimates noticeable reduction in run time in their laptops will be observed after 18 to 24 months. According to Leyden Energy, their batteries have one of the highest energy densities and run times for lithium-ion laptop batteries on the market, with 440 watt hours per liter and over 1,000 cycles.


Standard lithium-ion batteries use a salt-based solvent within the electrolyte that starts degrading at a temperature of between 70 to 80 C, while Leyden’s salt-based solvent doesn’t degrade until about 300 C. Thus, since the batteries can operate at higher temperatures than traditional batteries, they are able to provide a full charge for a longer amount of time.


Boston Power released a three-year lasting lithium-ion battery in 2008. The company has a partnership with ASUS, and the ASUS B Series notebooks are powered by Boston Power’s batteries. Currently Leyden is only able to offer laptop replacement batteries, so until they strike a deal with a major laptop manufacturer and get the battery right in the laptop, they might have a hard time competing with Boston Power. Right now Leyden Energy is working with Brammo to supply the battery for its electric motorcycle the Empulse. The company has also received $2.96 million in grants from the California Energy Commission to produce ten electric vehicle (EV) batteries per month. Leyden Energy hasn’t yet determined the exact price of the battery, but the three-year battery will be less than double the cost of a one-year battery.

Low-Cost Laptops for Kids in Need

Welcome to a Laptop Battery specialist
of the Apple Laptop Battery   First post by: www.itsbattery.com


In a rural Cambodian village where the homes lack electricity, the nighttime darkness is pierced by the glow from laptops that children bring from school. The students were equipped with notebook computers from a foundation run by MIT Media Lab founder Nicholas Negroponte and his wife Elaine.


"When the kids bring them home and open them up, it's the brightest light source in the home," said Negroponte. "Parents love it."


Negroponte and some MIT colleagues are hard at work on a project they hope will brighten the lives and prospects of hundreds of millions of developing world kids. It's a grand idea and a daunting challenge: to create rugged, internet- and multimedia-capable laptop computers at a cost of $100 apiece.


That's right, the price of dinner for four at a moderately priced Manhattan restaurant can buy a Third World kid what Negroponte considers an essential tool for making it in the 21st century. The laptops would be mass-produced in orders of no smaller than 1 million units and bought by governments, which would distribute them.


Ambitious projects to bridge the digital divide in the developing world at low cost have had a shaky track record. Perhaps the best example is the Simputer, a $220 handheld device developed by Indian scientists in 2001 that only last year became available and isn't selling well.


But Negroponte and MIT colleagues Joe Jacobson and Seymour Papert aren't deterred.


For one, three corporate partners have committed an initial $2 million apiece to the initiative and pledged to serve as suppliers for the "one laptop per child" project: Sunnyvale, California, Advanced Micro Devices, which will bring expertise in processors; "Do No Evil" search engine king Google; and News Corp., Rupert Murdoch's media company with global satellite capabilities.


The mission: to make laptops as ubiquitous as cell phones in technology-deprived regions. Negroponte's pitch: The cost of a laptop comes in far lower than a child's textbook expenses for the computer's lifespan.


"It's a way of having the children be the agents of change," Negroponte told The Associated Press. "They bring the device home, and then the parents look over their shoulder." He thinks it's extremely important that individual children own laptops; it will ensure they'll be well-maintained.


In design and function, Negroponte wants the $100 laptop to "be so close to the current laptops as to be nearly indistinguishable," but acknowledges that the machine will have a relatively slow processor and modest storage capacity paired with barebones software.


The biggest challenge, he says, is designing a display that doesn't put the price out of reach or drain the battery such as Apple A1175 Battery, Apple A1185 Battery, Apple M9324 Battery, Apple M8403 Battery, Apple M7318 Battery, apple PowerBook G3 Battery, Apple PowerBook G4 Battery, Apple PowerBook G4 15 inch Battery, Apple A1012 Battery, Apple M8511 Battery too quickly.


Details are still being worked out, but here's the MIT team's current recipe: Put the laptop on a software diet; use the freely distributed Linux operating system; design a battery capable of being recharged with a hand crank; and use newly developed "electronic ink" or a novel rear-projected image display with a 12-inch screen.


Then, give it Wi-Fi access, and add USB ports to hook up peripheral devices.


Most importantly, take profits, sales costs and marketing expenses out of the picture.


"The technology challenge is real, and you need to make some breakthroughs, but most of the money is saved in other ways," said Negroponte, who pitched the project in January at the World Economic Forum in Switzerland, the annual confab of global powerbrokers.


Negroponte has also met with Chinese and Brazilian officials to discuss expected orders and production in those countries, which would create local jobs. Two prototypes have been built, and test units could be shipped by the middle of next year. The project would essentially be nonprofit, with about $90 covering hardware for each computer and an extra $10 for contingencies or a small profit margin depending on how each government's order is structured.


Yet even if all those hurdles are surmounted, some question whether a $100 laptop project is the answer to bridging the global digital divide.


"Even if you give the laptops out for free, internet access and even electricity are huge problems," said Marc Einstein, an analyst with Pyramid Research, a Cambridge telecommunications consulting firm.


Negroponte and Co. have part of that solved, at least in theory: Out of the box, the $100 laptops will be able to communicate with one another using peer-to-peer mesh networking. That doesn't directly solve the internet or electricity problem, though.


Al Hammond, director for the nonprofit World Resources Institute's Digital Dividend project in Washington D.C., worries about customer support in poor, rural areas.


"The key is to create something affordable and sufficiently robust to protect against voltage surges, against dust, and against being dropped, and against all the perils of the internet," Hammond said. "Those things are more important if the nearest computer tech is three villages away and you don't have an air-conditioned office to work in."


Like Hammond, Andy Carvin, director of the Newton-based nonprofit Digital Divide Network, applauds the project's goals, calling an extremely low-cost, durable laptop "one of the holy grails of bridging the digital divide."


But he said increasingly sophisticated and versatile wireless handhelds may gain favor over laptops as the developing world's online tools of choice.


"That's not to suggest we should not have an inexpensive laptop," Carvin said. "They're parallel tracks, and it's probably a healthy competition to have both."


The digital divide remains vast: The technology research firm IDC examined 53 countries and determined that a household in Canada was 131 times more likely to own a personal computer than one in Indonesia -- hardly the world's least tech-oriented country.


The United States trailed Canada at No. 2 by that measure in rankings that examined computer use in countries that fall in the top third for advanced technology use.


Negroponte says his promotion of the $100 laptop project at the World Economic Forum meeting has helped it gain momentum.


"People are now calling me saying, 'We'd like to participate, and not only can we participate, but we can do it cheaper, or we can create better performance in this laptop,'" he said.


"People are saying, 'My God, this is real.'"

Booze to Fuel Gadget Batteries

Welcome to a Laptop Battery specialist
of the Apple Laptop Battery   First post by: www.itsbattery.com


Recharging your laptop might one day become a simple matter of giving it a shot of tequila. A new breed of battery, fueled by alcohol, may become the power source of choice for portable electronics.


The battery is a variation on the biofuel cell. A standard fuel cell works by continuously changing the chemical energy of a fuel and an oxidant to create electrical energy. A biofuel fuel cell uses biological molecules -- in this case, enzymes -- to catalyze this reaction.


Scientists have experimented with biofuel cells for years, but so far have been unable to engineer any that produce power for more than a few days.


The team behind the new battery has produced a constant current from its biofuel cell that is still going strong after two months. The researchers from Saint Louis University attribute their success to the fuel and to the environment they engineered for the enzymes that create the reaction that produces electricity.


Prior experiments have used methanol, another type of alcohol, as fuel. The Saint Louis team chose ethanol.


"A big advantage is that ethanol is not toxic like methanol, so it is easier to deal with," said team leader and assistant professor of chemistry Shelley Minteer.


Ethanol is also easier to get hold of than methanol -- as long as you're 21.


"You can use any alcohol. You will be able to pour it straight out of the bottle and into your battery," said team member Nick Akers, a graduate student. "We have run it on various types. It didn't like carbonated beer and doesn't seem fond of wine, but any other works fine."


Users won't have to deplete their liquor cabinets to keep their portables powered up, because all it takes is a few drops.


"Once the system is fully optimized, probably one to three drops of alcohol could power your laptop for a month," Akers said.


Ethanol is also more active than methanol in the presence of enzymes -- the other essential ingredient in the new battery such as Apple A1175 Battery, Apple A1185 Battery, Apple M9324 Battery, Apple M8403 Battery, Apple M7318 Battery, apple PowerBook G3 Battery, Apple PowerBook G4 Battery, Apple PowerBook G4 15 inch Battery, Apple A1012 Battery, Apple M8511 Battery. Enzymes are molecules found in all living things that speed up the body's chemical processes. The Saint Louis team uses them as catalysts inside their biofuel cell.


"The enzymes we use are called dehydrogenase," Akers said. "We chose these because they strip protons from alcohol, and this is the reaction we need to get electricity."


Enzymes are not alive like cells or bacteria, but they have to be active for the biofuel cell to work. Keeping the sensitive catalysts active has caused problems in the past.


"Enzymes are fairly fragile and can be denatured if there are any changes in temperature or in the pH level (acidity or alkalinity)," Minteer said. "Given the proper environment, an enzyme should last for long periods of time. It is creating this environment in a fuel cell that researchers have struggled with for years."


Minteer and her team overcame this conundrum by coating the biofuel cell's electrodes with a polymer that contains tailored micelles, or pores, which provide an ideal microenvironment for the enzymes to thrive.


After two months of producing a constant current with its biofuel cell, the Saint Louis team is optimistic.


"There's no evidence that it is going to stop tomorrow. We don't know yet how long it's going to last. Could be six months," Akers said.


Scott Calabrese Barton, assistant professor in the Department of Chemical Engineering at Columbia University, said the Saint Louis team's test results seemed promising.


"It's a great accomplishment that they were able to turn ethanol into an oxidizer and get a stable current," Barton said.


However, he said the rate of power generated is also an important factor. "If it is low, then it's only suitable for certain applications, like sensors."


Minteer said the team is working on ways to increase their biofuel cell's power density. Currently the team's battery can produce 2 milliwatts of power per effective square centimeter. The average laptop requires 500 milliwatts to operate.


The team is also looking at ways to produce a battery designed to fit today's portables that can also produce the necessary power output.


"It's like a radiator in car," Akers said. "It's folded, and all those ridges and folds give it a high surface area so the effective surface area becomes tremendously huge. You can do this on a micro scale so that the effective surface area of the electrodes is enormous. This is what we are doing in the designing process."


Akers is confident the team will have a working prototype in a year, and that the finished product will hit store shelves a year later.

Want to Massively Increase Your Laptop Battery Life

Welcome to a Laptop Battery specialist
of the Compaq Laptop Battery   First post by: www.itsbattery.com


If you want to increase the amount of charge that you get out of your laptop battery and also increase the time before you will have to buy a replacement laptop battery, then you have found what you are looking for. This article will show you a few little tips and tricks that you can implement on a daily basis to greatly increase your laptop battery life. A lot of people that I know do not have any idea about how to treat the batteries in their laptops resulting in them having to replace them every six months! This can be avoided. Read on to find out more.


Depending on the type of battery that is in your laptop, you will have to do different things. There are currently four main types that are in use today with one type being phased out and another type being phased in. The four main types are lithium ion batteries (or Li-Ion batteries) such as Compaq Presario 1200 Battery, Compaq Presario 1800 Battery, Compaq Presario 700 Battery, Compaq Presario 900 Battery, Compaq Presario 1700 Battery, Compaq Armada E500 Battery, Compaq EVO N100 battery, Compaq Evo N1020V battery, Compaq Evo N1000C battery, Compaq Evo N115 battery, nickel metal hydride batteries (or NiMH batteries), nickel cadmium batteries (or NiCd and sometimes NiCad) and lithium polymer batteries (or Li-po batteries). The oldest type in current use is the nickel cadmium kind and the new type that is currently gaining popularity is the lithium polymer battery.


Nickel metal hydride and nickel cadmium batteries are both susceptible to a thing called battery memory degradation. This is where, over time, the battery cannot hold as much as it used leading to hugely reduced running times of your laptop. To stop the severity of this effect there are a few little things that you can do such as not recharging the battery until it is totally empty, and making sure that you leave as much room as possible between each recharge. Also, you should ensure that each time you perform a recharge, you charge the battery to its full capacity.


If your computer has a lithium ion battery or a lithium polymer battery there are a few different steps that you need to take to ensure that you keep your laptop batteries maximised. You need to ensure that you do not run these types of batteries totally dry. This can lead to damage to the internal chemical makeup and cause irreversible damage. Most new laptops come with power management programs so you do not have to worry about this as they will shut down if the charge in the laptop battery gets down to below 10 percent. Also try to take the battery out of the laptop if you have it plugged into an AC power supply for most of the time. Before you do this, ensure that the battery is fully charged and remember to put the battery back in the laptop before you remove the power supply or your computer will instantly turn off.


Following the above simple steps is not a hard thing to do. It will save you a lot of time, effort and money. New laptop batteries can be quite expensive so performing a few little tasks each time you use your laptop is a small price to pay for the rewards that you will receive in the future.


For more information about how to look after your laptop battery head over to this great article that will give you all the information you will ever need when it comes to increasing laptop battery life.

Tech News

Welcome to a Laptop Battery specialist
of the Compaq Laptop Battery   First post by: www.itsbattery.com


The Vatican is putting together its own World Wide Web site to make news of the pontiff's daily doings, speeches and some Holy See documents available to Internet users.


"It's something that should arrive in several months," said the Rev. Ciro Benedettini.


Separately, the Vatican press office this month began computerizing the daily bulletin of the pope's activities and offering it to news organizations via a dial-up service.


The service is free during a five-month trial period. News organizations, and eventually embassies to the Vatican and other institutions, will then have to pay for access, papal spokesman Joaquin Navarro said.


IBM EYES INVENTORY UPGRADE


IBM, in another corporate-devised strategy, is changing the way it handles its inventory system to ensure it has enough PCs to meet holiday-season demand.


Last year, a critical shortage of Aptiva consumer PCs led to big losses in the PC unit and a loss in market share to players such as Compaq Computer Corp. and Packard Bell Electronics.


"It's no secret in the industry that IBM has been mediocre in logistics," Bob Stephenson, recently appointed head of IBM Personal Computer Co., said at a press conference at Comdex.


BATTERY SHORTAGE FEARED


A fire two weeks ago in a Sony Corp. battery plant in Japan has raised concerns about whether there will be a shortage of batteries for portable computers such as Compaq Armada M700 Battery, Compaq EVO N400c Battery, Compaq EVO N410c Battery, Compaq EVO N600C Battery, Compaq EVO N610C Battery, Compaq EVO N620C Battery, Compaq Presario 1200 Battery, Compaq Presario 1800 Battery, 116314-001, Compaq Presario 700 Battery, Compaq Presario 900 Battery.


Manny Vara, spokesman for Sony Electronics' U.S. division in San Jose, Calif., said last week that the fire idled all production in the lithium ion battery factory in Koriyama, Japan. But he said he believed that supplies will not be significantly affected because of the company's production plans.


Lithium ion batteries are the most widely used batteries for laptop computers, and Sony makes more than 70 percent of the world's supply.


POSTAL PHONE CARDS TESTED


You've probably seen phone cards sold at all manner of places these days. Now they may be coming soon at your local post office.


The U.S. Postal Service began testing the sale of the cards last week at post offices in eight cities. The cards, being sold through an agreement with American Express and MCI, are available in denominations from $5 to $100.


Users activate the card with a personal identification number through a pay phone or touch-tone phone. Cities where use of the card is being tested are Austin, Texas; Columbus, Ohio; Miami; Albuquerque, N.M.; Providence, R.I.; San Antonio; San Diego; and Salt Lake City.

Which Batteries Are Best?

Welcome to a Laptop Battery specialist
of the IBM Laptop Battery   First post by: www.itsbattery.com


Home Clinic: I need some help sorting through all the household batteries on the market. There are so many to choose from and quite a bit of variation in price. Which is the best? Also, when batteries run down, should I just dispose of them in the household trash? S.G.H., Renton


Dear S.G.H.: You said it! Buying batteries isn't what it used to be. The best choice depends on what the battery is going to power, the cost and the battery life.


The major types are general purpose, heavy-duty, alkaline and rechargeable. Of these, rechargeable batteries last longest, cause the least environmental damage and cost less over time. Savings over disposable batteries might be $100 to $275 over the life of the battery such as IBM ThinkPad T61 battery, IBM ThinkPad X41 battery, IBM ThinkPad X40 battery, IBM ThinkPad X20 battery, IBM ThinkPad R60 Battery, IBM ThinkPad T60 Battery, IBM 40Y6797 Battery, IBM 40Y6799 Battery, IBM FRU 92P1139 Battery, IBM FRU 92P1141 Battery. For example, one pair of rechargeable AA batteries can replace as many as 150 alkaline batteries!


Although there are several types of rechargeable batteries, nickel cadmium (nicad) is the type you are likely to buy for toys and home gadgets. Like disposable batteries, nicads contain their share of toxic heavy metals. Since nicads can be used longer than disposable batteries, however, they significantly reduce the number of batteries entering the waste stream.


Nicads can be recharged and used hundreds of times. Expect an initial cost of $2.50 to $8 apiece, depending on the size. They are available at most stores. The electricity to charge them cost pennies, but the charger may run anywhere from $15 to $50.


Nicads lose about 1 percent of their charge daily even when they are not being used. They are unsuitable for devices like cameras, smoke detectors and flashlights that are left idle for long stretches.


Consumers will see new types of batteries entering the market as technology advances. Keep your eyes out for nickel metal hydride batteries (now powering many laptop computers). They function the same as nicads, without the toxic cadmium, although they still contain nickel, another toxic heavy metal.


The new rechargeable alkaline batteries, available in some stores and catalogs, eliminate the problem of nickel and cadmium and have virtually no mercury.


Battery disposal


Americans use 2.5 billion batteries a year - about 2 pounds of batteries per household. Recycling programs for household batteries have yet to be fully developed, and most used batteries wind up in local landfills. However, many communities have placed a heavy emphasis on ensuring the safest method of land-filling expired batteries.


If you live outside King County, contact your solid-waste department for disposal information. In King County, residents can throw general household batteries into their household garbage.


For waste-disposal information, call 296-4466. For information on hazardous waste call 296-4692.

Laptop from eMachines isn't what it used to be

Welcome to a Laptop Battery specialist
of the IBM Laptop Battery   First post by: www.itsbattery.com


When I mentioned to colleagues that I was writing a review of a laptop from computer maker eMachines, most of them wondered why I bothered. Their recollection of eMachines, devoid of recent experience, was of cheap PCs that couldn't compare on features.


The latest laptop from eMachines, however, shows that the company can beat Dell, Toshiba, Compaq and IBM on the price-to-features ratio by offering a single laptop model instead of the several lines and dozens of configurations that the bigger firms specialize in.


On performance, appearance and features, I found the $1,199 eMachines M5310 comparable to more expensive Intel Pentium M and Centrino units that I had spent time with in April. Life of battery such as IBM ThinkPad T61 battery, IBM ThinkPad X41 battery, IBM ThinkPad X40 battery, IBM ThinkPad X20 battery, IBM ThinkPad R60 Battery, IBM ThinkPad T60 Battery, IBM 40Y6797 Battery, IBM 40Y6799 Battery, IBM FRU 92P1139 Battery, IBM FRU 92P1141 Battery is the only area that needs improvement, but even there, they may still have other laptops beat because of price.


From the minute I took the M5310 out of the box, I was hooked. Let's start with the beautiful, luxurious, 15.4-inch screen (1280 by 800 pixels). The brightness is something staggering, especially when placed next to other LCD displays. It's crisp and legible, and the 64 megabytes of video memory keep the display from lagging.


The machine, which uses an AMD Athlon XP-M 2400+ processor, ships with an appropriate 512 megabytes of PC2100 RAM, which is fast, though not cutting edge. Many comparable laptops include only 256 MB, which is inadequate for running business applications under Windows XP.


Although I didn't run formal speed tests, I found no lag in normal activities, such as browsing the Web, editing text, downloading files, installing updates or using business applications. The reboot time is extremely small: After installing software and selecting Restart, the laptop was ready to go in less than a minute.


The M5310 has a profusion of built-in ports. It sports a single IEEE 1394 or i.Link connector for use with digital camcorders and Apple iPods; three USB 2.0 (480 Mbps) connectors in the back; audio in and out; a 56K V.92 modem; and a 10/100 Mbps Ethernet jack.


The unit also has a VGA and printer connector for external monitors and printers along with S-Video out for high-quality television display of DVDs. It can accept PC cards, too.


Inside, there's more: a DVD-ROM/CD-RW burner that can write CD recordable disks at 24x speeds.


The M5310 also features the latest flavor of Wi-Fi, 802.11g, using an internal adapter provided by consumer market leader Broadcom, which makes wireless chips for Apple.


I priced comparable Pentium 4-M systems as a benchmark. A Compaq model comes with the same AMD processor, memory and hard drive, has a lower-resolution 15-inch display, omits the audio input port, and only has a single USB 1.1 (12 Mbps) connector for the same price.


What's the M5310's biggest drawback? Battery life. EMachines rates its battery at 2.5 hours, and additional batteries cost $120 each.


The eMachines comes down to choice. People looking for a portable that doubles as a desktop want the most features and the most flexibility. The eMachines meets this goal squarely without requiring all of the decisions that often go into laptop purchases.

Buyer be wise when looking for a laptop

Welcome to a Laptop Battery specialist
of the IBM Laptop Battery   First post by: www.itsbattery.com


By one estimate, they outsold desktops for the first time in the United States in the second quarter of this year.


Many people buy laptops that will never leave a desk, just because they like having all of the computer in one unit.


But as laptops have reached mainstream status, they have not become a simpler purchase to make. They're marketed just like most other electronic items: Manufacturers skimp on features and capabilities to save money, or so that you'll buy other products and services from them. It's up to you to spot what got left out.


The biggest area of compromise is the battery. It's bad enough that many laptop vendors act as if battery life is either a state secret or a mystery; there is no EPA estimate or Energy Star certification for this sort of thing.


But several of these companies seem to have also adopted one of the worst habits of the digital-camera business.


Just as some digicam manufacturers bundle "starter" memory cards that accommodate only a handful of photos, some laptop makers — including Dell, Gateway and Hewlett-Packard — ship computers with batteries that will expire before you can finish watching a movie.


If you want a longer run time, you'll have to upgrade to a heavier, sometimes larger replacement battery such as IBM ThinkPad 240Z battery, IBM ThinkPad A30 battery, IBM ThinkPad A31 battery, IBM ThinkPad 600 battery, IBM 02K7016 battery, IBM ThinkPad G40 battery, IBM 08K8026 battery, IBM ThinkPad T21 battery, IBM ThinkPad T20 battery, IBM ThinkPad X61 battery. If you don't think to do this as you order the machine online, you wind up paying for two batteries, one of which will be doomed to collect dust in a closet.


Laptop weights are another area where customers can be led astray. The problem isn't with the many "desktop replacement" models that weigh 7 or more pounds and aren't made to be taken anywhere. The problem is with laptops advertised as "thin and light."


Once you set it up for any kind of portable computing, that featherweight may have bulked up. Those optional longer-life batteries can add half a pound by themselves, as can the AC adapter. Many tip the scales at almost a pound, even though the adapters included by more thoughtful manufacturers weigh less than half as much.


Laptop screens can have their own quirks to consider. A larger screen may not show any more detail than a smaller display with the same resolution; it will just make the text and icons on the screen look bigger and slightly duller.


Just as in desktops, it's easy to buy too much processor in a laptop. For most uses, even the slowest processor available runs more than fast enough.


Do not let yourself get spooked by the relatively low clock speeds of many laptop processors, because these no longer effectively measure performance. A Pentium M, for example, computes just as quickly as a Pentium 4 with a much higher gigahertz figure.


Memory is more important overall; spending $50 to double a computer's memory from 256 to 512 megabytes will usually yield a greater speedup than dumping $100 on a faster processor.


If you're buying a Windows laptop, be wary of those with "integrated" graphics accelerators, which borrow memory from the system — often up to 128 megabytes — to draw three-dimensional graphics when you play games.


Laptops advertise hard drives of 60, 80 or 100 gigabytes, but you always get less than that.


First, everybody in the industry uses a definition of "gigabyte" that artificially pads out the size of the drive by about 7 percent.


Second, many vendors of Windows laptops use some of the hard drive to hide a set of system-recovery programs, including a backup copy of Windows, instead of providing those on separate CDs or DVDs.


Third, a few Windows machines now include a separate, simpler software environment that you can run instead of Windows when you only want to watch a movie or listen to music. That eats up a little more disk space of its own.


Most non-IBM laptops include a slot for the memory cards used in digital cameras, handheld organizers and cellphones, but — unlike on desktops — these slots rarely accommodate every card format.


If your portable gadgets use SD Cards, the most popular type, you should be fine. Otherwise, you'll have to check the fine-print specs for a laptop to see what cards it does accept.


Communication and expansion — how you get data in and out of the machine — are, by contrast, refreshingly straightforward to decipher.


The more USB ports, the more gadgets you'll be able to plug in, from printers to a digital camera to a digital-music player.


A FireWire port can accept an iPod or a camcorder, should you want to make home movies. A modem, Ethernet jack (for a wired network) and Wi-Fi (for the wireless kind) are pretty much standard.


The only options to ponder are Bluetooth, which can link a laptop wirelessly to some newer cellphones and handheld organizers, and a PC Card slot, which you'll likely need only if you plan to use a cellular data service such as Verizon Wireless' BroadbandAccess.


Finally, there are the manufacturers' service and support policies. Everybody offers a minimum period of warranty coverage when you can call for help and not be charged, but those periods vary.


As an option, vendors are pushing service contracts and warranty extensions. It's comforting to think that, by paying an additional $300 or $400, you've eliminated all risk from your computing purchase.


But you'll also wind up spending a large fraction of the computer's value in the process. And at some point, the laptop will outlive its usefulness anyway.


Unless you think you're going to abuse the laptop heavily, you're better off setting that money aside for the next computer or spending it to get whatever the vendor left out of your machine.

Nanotechnology in ophthalmology

Welcome to a Laptop Battery specialist
of the IBM Laptop Battery   First post by: www.itsbattery.com


An increased level of sophistication would allow external control of the device by, for example, light-modulated control signal. This level of control could stop and start a device and alter the drug delivery rate. In a development of this communication function, it would also be possible to interrogate the device by activating a 'talkback' mode, where data could be read back from the device using optically coded techniques.


Encoded data could include, for example, details of the equivalent volume of the drug dispensed and the status of the power source. Modern electronics is certainly more than capable of providing this level of functionality. A key element of the design of such a system would be the resilience of the software.


Ideally, power sources should be able to power the application without the requirement to top-up or replace the source. Materials technology used for battery function require high energy/volume factors. Energy transfer into energy source using microwaves and electromagnetic induction are also possible. Such systems have already been developed for larger implant systems by Mussivand et al.7 High energy density rechargeable batteries such as IBM 08K8192 Battery, IBM 92P1101 Battery, IBM 92P1089 Battery, IBM 92P1087 Battery, IBM 08K8196 Battery, IBM 92P1102 Battery, IBM 92P1077 Battery, IBM 92P1073 Battery, IBM 08K8199 Battery, IBM 08K8198 Battery, integrated into silicon circuits for biomedical implantation applications, are also described by Notten et al.8 A range of technologies have been identified as having potential for miniature pump delivery systems. In particular, MEMS technology9 is identified as a viable approach. The core element of such a pump-driving system is indicated in Figure 2, where alternate voltage pulse (positive and negative) causes deformation of membrane in opposite senses.


On the inlet phase, fluid is drawn into the pump chamber with outlet value closed. On the outlet phase, fluid is driven into the outlet channel with the inlet channel closed. Such pump systems tend to have an optimum frequency for drug delivery rates. A key design element is to minimise the operating stress on the diaphragm material to prevent its failure.


Advanced design techniques of extensive numerical simulation are used to optimise design configurations. Electro wetting, electrochemical and ion conductive polymer film (ICPF) actuator micro pumps are further described by Nisar et al.10 Provided sufficient energy and also sufficient volume of drug is available, existing micro pump technology can deliver this function.


Drug reservoir options In association with the capacity of the power source, the issue of volume of drug reservoir is another key issue and, if the issue of energy transfer to micropumps can be achieved, is the key limiting factor of the technology.


In terms of Lucentis administration, the initial loading regime is 0.05ml in the first three months and then 0.05ml administrations at monthly intervals if required. In the first year a typical dose could be 0.6ml per year. It is also relevant to note that the mode of drug administration is intermittent and not continuous within the conventional administration pattern.


While further research on drug diffusion is required, it may only be required to deliver an initial loading dose of 0.05ml, followed by daily equivalent doses of around 0.0015ml over a year. In this mode, the pump device is essentially dormant and is activated for a short time for each daily administration. The dominant power requirements of the device may therefore be for a hibernation mode in the monitoring electronics.


The volume of the micro pump system, however, needs to be considered in relation to the total volume of the eye, which is typically in the range 7.00ml to 8.00ml. Also, the emptying of 1ml of fluid into the eye requires the filling with an equivalent volume of displaced fluid. Where would this come from? Also, the stability of the injected drug is another relevant issue. Lucentis has a short active half life and may be an unsuitable choice for micro pump delivery, since the drug would presumably have to retain efficacy over a period of at least a year.


The technology of micro pumps does offer, in their time line of development, future exciting capabilities. Drugs from separate reservoirs can be delivered as a 'cocktail' - with the proportion of drug mix as well as separate drug rates part of the selectable options.

Conclusion Technologies

Welcome to a Laptop Battery specialist
of the IBM Laptop Battery   First post by: www.itsbattery.com


There is also the possibility of making such devices 'smart' so they can be remotely controlled or even, in a more advanced scenario, be self-regulating. Further review of drug metabolism in the posterior chamber is provided by Choonara et al.5 Designs for micro pumps The rapid development of microelectronics, however, has changed the levels of function and control of possible implanted miniature pump devices. Some initial developments have already been reported.6 Figure 1 indicates the generic structure of such an implanted pump delivery system.


At the simplest level, the miniature pump would be self-contained, with its own power source, drug reservoir and no external control over drug delivery rates. The device would be limited by the capacity of the power source and the level of drug able to be contained in the reservoir. At the end of the device's life it would have to be explanted from the eye and possible insertion of another similar unit be considered.


Conclusion Technologies already exist to enable drug delivery to the posterior chamber of the eye using micropump technology. Careful thought, however, must be given to the long-term stability of any drug selected for such delivery.

Dell hit with class action suit over Inspiron

Welcome to a Laptop Battery specialist
of dell laptop battery   First post by: www.itsbattery.com


Dell, which struggled last year with a massive battery recall, now faces legal action in Canada from a user who complained the company continued to sell some models in its notebook line after it knew they suffered from problems.


The class action suit was filed in the Ontario Superior Court by Thad Griffin, a resident of Ontario, on behalf of other users of Dell Inspiron laptops. It alleges design defects make certain Inspirons susceptible to overheating and that this overheating will cause extra wear to the motherboard, resulting in premature failure.


While the class action is not directly related to a massive recall of overheating laptop batteries such as dell Inspiron 640m battery, dell Y9943 battery, dell RC107 battery, dell Latitude D620 battery, dell 312-0386 battery, dell PC764 battery, dell TD175 battery, dell Latitude D820 battery, dell Latitude D830 battery, dell MM165 battery last year, the publicity from that issue has haunted Dell. The company's share price plummeted after the news broke in August and only slowly recovered through November. Dell has attempted to rebuild its image by accelerating initiatives such as its carbon-neutral strategy, announced last week.


The legal action, filed at the end of last week, applies to Inspiron models 1100, 1150, 5100, 5150 and 5160. It seeks to have Dell Canada replace the defective computers or cover the cost of repairs. The justification for this, according to a lawyer in the case, is that there appears to be "a systemic problem."


"Generally, we're seeing these symptoms or problems occur after the warranties run out. And it would appear as though it's a systemic problem that's inherent to all of these Inspiron models. At least, that's the feedback we're getting," Joel Rochon, a partner of Rochon Genova, the firm conducting the case, said in an interview with the Canadian press.


According to Rochon, there has been a "steady flow" of people bringing their problems to his firm.


But Dell computers do not have any inherent problems, according to Which, an independent product evaluation site in the U.K. that looked closely at Dell laptops after the company's August laptop battery recall because of reports of batteries overheating and catching fire.


"Our surveys show that Dell is one of the most reliable brands out there, but this type of incident could harm Dell's image badly," Kim Gilmour, a Computing Which magazine senior researcher, said at the time. "Dell did react quickly, but it could have reacted faster. It took the company several weeks to issue this mass recall of batteries."


A Which spokesman said the organization has not yet had to time to consider the current issues around the alleged problems with Dell's Inspiron.


When contacted on Monday, Dell would say only that it "does not comment on pending litigation, as a matter of corporate policy."

IBM hangs hopes on new ThinkPad laptops

Welcome to a Laptop Battery specialist
of the IBM Laptop Battery   First post by: www.itsbattery.com


That's the question hanging over the company as it completes the product road map for its notebook line and looks toward profitability for its PC division.


Armonk, N.Y.-based IBM next month will retire the ThinkPad 240 and 570 notebooks--two of its most popular ThinkPad models--and replace them with the ThinkPad X Series, as previously reported by CNET News.com.


The X Series completes an important transition started in May, when IBM replaced the ThinkPad 600 with the T--as in "thin and light"--series and the ThinkPad 390 and 770 with the A, or "all-in-one," series.


Until recently, IBM had been a relative bit player in the worldwide notebook market, according to market researcher Dataquest. Dell Computer, for example, led overall global notebook sales in the second quarter this year, with 21.5 percent market share, followed by Compaq at 16.6 percent and Toshiba with 13.4 percent. IBM came in fourth with 12.1 percent, with HP pulling up the rear at 5.8 percent share.


But since the May launch of A and T ThinkPad models, IBM has picked up momentum in the lucrative corporate market, the biggest buying segment. In July, IBM had 44.6 percent market share though corporate dealers selling to Fortune 500 companies, double that of second-ranked Toshiba, according to NPD Intelect.


With the X Series, IBM is trying to find the middle ground between the 240, a mini-notebook weighing 3 pounds and featuring a 10.4-inch TFT display, and the more portly 570, its 4-pound cousin packing a 13-inch screen and split-level design. For the lightest weight, the 570 snaps off a base containing the DVD drive and other options.


The X Series will come with a 12.1-inch display, 600-MHz Pentium III processor, 128MB of memory and 12GB hard drive and will weigh close to 3 pounds, said a source familiar with the portable. Like the 240 and 570, the X Series will be available in just a handful of configurations. Five 240 models and two 570 configurations are currently available.


Other sources familiar with the product said to expect the titanium-reinforced casing used in A and T series ThinkPads to appear in the X Series. The sturdy, lightweight material makes up the lid on A20 models and the T20's top and bottom covers. The material means IBM can bring in an all-in-one design with a 14.1-inch display at 6.4 pounds.


Because IBM is spotlighting portability in its marketing of the new systems, the company is expected to emphasize wireless computing more with X Series models than it did with other ThinkPads.


Like the A and T series, the ThinkPad X will feature a "portofino" port on the lid for snapping in Bluetooth wireless antennas and other peripherals, such as PC cameras. The ports allow people to connect peripheral devices, such as global positioning systems and MP3 players, to their notebooks.


Bluetooth, a wireless technology that lets smaller devices and peripherals automatically connect to each other, means people can connect to printers, Palm handhelds and other devices without cables or wires.


One feature the initial release of ThinkPad X portables won't have is Transmeta's Crusoe processor. During the PC Expo trade show, IBM showed off a ThinkPad prototype using the alternative to Intel and AMD processors.


Crusoe's appeal is that it runs cooler than competing processors and offers longer battery life because of the chip's lower voltage. In testing, IBM has squeezed eight hours of battery life out of Crusoe vs. about four hours for a ThinkPad 240 packing a 450-MHz Pentium III processor.


"This would be the kind of product the Transmeta chip would go into," ARS analyst Matt Sargent said. The chip is especially attractive for ultra-lightweight portables, he added.


For now, IBM customers will have to be satisfied with about four hours life of battery such as IBM ThinkPad T40 Battery, IBM ThinkPad T41 Battery, IBM ThinkPad T42 Battery, IBM ThinkPad T43 Battery, IBM ThinkPad R50 Battery, IBM ThinkPad R51 Battery, IBM FRU 08K8193 Battery, IBM 92P1060 Battery, IBM 08K8214 Battery, IBM 08K8195 Battery, IBM 08K8193 Battery, comparable to the ThinkPad 240. A Crusoe-based ThinkPad X model is expected as early as the fourth quarter, but likely later, said a source familiar with IBM's product strategy.


IBM's bigger problem is launching the new model right in the middle of a supply crunch. Shortages of a single component used on ThinkPad and Netfinity server motherboards during the second quarter cost the computer manufacturer $250 million in lost sales.

Fujitsu to bring Transmeta laptop to U.S.

Welcome to a Laptop Battery specialist
of the Fujitsu Laptop Battery   First post by: www.itsbattery.com


Transmeta, which last week ousted its CEO and reported it sold just $5 million worth of chips in the third quarter, has found a niche with Japanese PC makers but has struggled to crack the U.S. market. Sony, Casio and NEC have introduced notebooks for sale here, but Compaq Computer and IBM announced plans to stick with Intel's low-power chips.


"It's good to see that they can get some design wins," said Nathan Brookwood, analyst at Insight 64. However, Brookwood said Transmeta still faces challenges in convincing PC makers to adopt Crusoe.


Brookwood said Fujitsu and others are getting better life of the battery such as Fujitsu FPCBP80 Battery, Fujitsu FPCBP77 Battery, Fujitsu FPCBP68 Battery, Fujitsu FPCBP63 Battery, Fujitsu FPCBP95 Battery, Fujitsu LifeBook C1320 battery, Fujitsu FPCBP115 Battery, Fujitsu LifeBook C1321 battery, Fujitsu FPCBP152 battery, Fujitsu FPCBP130 battery, but chips are only a small part of the energy equation.


"The processor is not the major consumer of power in this class of product by far," Brookwood said. "People who are getting improved battery life are doing it through their approach to LCD technology and disc technology as much as, or more than, chip technology."


The new Fujitsu notebook, known as the LifeBook P, is Fujitsu's first U.S. model with a Crusoe chip, although the PC maker has been selling two Transmeta-based models in Japan, according to a Fujitsu representative. The company said the U.S. model should be available in mid-November.


"We recognized the acceptance of its predecessor notebook in the Japanese and Asia-Pacific markets and are confident the LifeBook P Series will succeed here in the U.S.," Sara Nelson, Fujitsu's vice president of marketing, said in a statement.


The LifeBook P will start at $1,499 and can either hold a combination DV-CD recording drive or a second battery that Fujitsu says gives the computer up to 14.5 hours of battery life. It comes standard with a 10.6-inch SXGA TFT screen, a 20GB hard drive, 128MB SDRAM, ATI Rage Mobility-M video card and an external USB floppy drive.


The chip used in the LifeBook P, the 800MHz Crusoe 5800, has been delayed, but the Fujitsu representative said problems with the chip did not affect the timing of the LifeBook launch. Transmeta originally announced the 5800 on June 25.


Sony last week announced a new PictureBook based on the 5800. The C1MV, also due to hit store shelves in mid-November, uses a 733MHz Crusoe 5800-series processor, has a 20GB hard drive and will retail for around $1,900.


Transmeta shares have been trading below $5 since early this summer and have been hovering between $1 and $2 in recent weeks.

A peek into Fujitsu's future

Welcome to a Laptop Battery specialist
of the Fujitsu Laptop Battery   First post by: www.itsbattery.com


Colored electronic paper was just one of the futuristic technologies showcased last week at the Fujitsu North American Technology Forum 2007, an open house of sorts for Fujitsu Labs.


The two-day event, a first of its kind in North America for the company, allowed Japan- and U.S.-based engineers to show off products intended to make life and business more efficient for tasks ranging from reading and doing laundry to securing medical records.



With potential to change the way businesses communicate information, Fujitsu's color e-paper, which is essentially a thin liquid crystal display, is getting closer to market. For the first time, researchers released a hand-built prototype outside the Japanese labs where it's been incubating since 2004.


Similar in form factor to an e-book reader, the Fujitsu version displays color--not mind-blowing color, but still more visually appealing than standard black and white--and is aiming for more commercial applications. Fujitsu's version is "green" and also appeals to the wallet: there is no power required to show an image. That means the technology can eventually be used for signage without having to replace batteries such as Fujitsu FPCBP80 Battery, Fujitsu FPCBP77 Battery, Fujitsu FPCBP68 Battery, Fujitsu FPCBP63 Battery, Fujitsu FPCBP95 Battery, Fujitsu LifeBook C1320 battery, Fujitsu FPCBP115 Battery, Fujitsu LifeBook C1321 battery, Fujitsu FPCBP152 battery, Fujitsu FPCBP130 battery.


Power is necessary to change the image on the film--say, to turn a page. But the power requirement is so low that focused energy from a wireless device, like a cell phone, is enough to do the job. Consequently, one of the coolest applications for color e-paper now is as an enhancement to small mobile devices, according to Fujitsu special projects consultant Dave Marvit.


Can't stand looking at Web sites on your handheld's itty bitty screen? Beam it from your phone to a piece of e-paper, like the 8-inch, 640x480 resolution reader Marvit showed off, and you can see the page without squinting. If 8 inches seems too small, the Fujitsu researchers are currently working on a 12-inch version. Eventually, the displays will grow to 2.5 meters, said Mike Beirne, a Fujitsu spokesman.


Between now and next April, Fujitsu is looking to market color e-paper. While it's not ready for the real world just yet, it's at least getting closer.


RFID tag might be a bad word for privacy watchdogs, but hospitals and the hospitality industry most likely won't be offended by a more efficient wash cycle. Fujitsu makes a flexible, waterproof radio frequency identification (RFID) tag that can be ironed onto uniforms, hospital gowns and linens to track their location and status.


Fujitsu's tags can also carry more information about the item they are attached to than the RFID chips inside, say, a passport, because they uses FRAM, or ferroelectric random access memory. That type of memory--as opposed to DRAM--can be made on the same chip as the RFID chip, which saves space and, of course, money.


Since the tags don't need to be individually scanned, like a bar code does, gigantic piles of laundry can be read and registered at once. The idea is to make the process cheaper and faster. While each tag now costs between $2 and $3, by 2010 Fujitsu hopes to bring the cost down to less than $1 each, said Beirne.


Fujitsu is also continuing to develop the technique of hiding numerical information within images meant to be accessed through photos of the image. It's called steganography, and is much more fun than laundry because it helps you buy stuff. Actually, it also gives you access to information for which you may not know how to search.


For instance, if you see an ad in an outdoor lifestyle magazine for a pair of carving skis, and your mobile phone has Fujitsu's software installed, simply take a picture of the skis, and the ski maker's Web site, video or additional advertisement pops up on your phone. And it doesn't alter the image in a perceptible manner--the human eye can't detect the information contained in the image. Though not available in the U.S. yet, Fujitsu partnered with NTT DoCoMo, the largest mobile carrier in Japan, where the technology has been in use for about a year, said Fujitsu's Beirne, particularly for sightseeing information contained within tourism maps.


Fujitsu also showed off a way for human vein patterns to protect private information. Since every person's vein pattern in his or her hand is unique, researchers developed a way to use the pattern as a way to access secure information.


Using a hardware sensor--over which you place your palm--and Fujitsu's software, the PalmSecure tool not only reads a hand's vein pattern, it's also looking at the deoxidized hemoglobin inside those veins, also known as "the blue stuff." Basically it can tell if the blood inside those veins is warm and the person attached to the hand is alive, so people trying to get access to secure information, like government data or patient records, can't game the system.


Though the technology is sale worldwide, thus far only one U.S. customer, a hospital, is putting it to use, according to Fujitsu.

The scoop on new air travel battery rules

Welcome to a Laptop Battery specialist
of the Toshiba Laptop Battery   First post by: www.itsbattery.com


This caused me to perk up at my computer. After all, I routinely travel with at least three spare rechargeable lithium ion batteries (one for my computer, one for my Treo, one for my digital camera) and often more. On some trips, I might also carry various spare nonrechargeable lithium metal batteries for various gear. The checked-luggage thing was no big deal, but if I were truly limited to two spare batteries in my carry-on luggage, that would have been an issue.


The story kicked up the predictable firestorm, only somewhat muted by its appearance over the holidays. Fortunately, it turns out to be incomplete on a critical point. You can find more detailed background and analysis elsewhere, but I thought that it would be useful to reiterate a few critical points, given the incorrect information floating around (and the fact that the Department of Transportation Web page that "explains" the rule is written in rather confusing government speak).


Loose (i.e., those not installed in equipment) lithium and lithium ion batteries may, in fact, no longer be put into checked luggage.

The "two-battery limit" applies only to lithium ion batteries with more than "8 grams of equivalent lithium content, (which) is approximately 100 watt-hours." The Reader's Digest version is that this limit roughly corresponds to the largest notebook batteries such as Toshiba PA3383U-1BAS Battery, Toshiba PA3384U-1BAS Battery, Toshiba PA3285U-1BAS Battery, Toshiba PA3191U-1BAS Battery, Toshiba PA3166U-1BAS Battery, Toshiba PA3331U-1BAS Battery, Toshiba PA3098U-1BAS Battery, Toshiba PA3084U-1BAS Battery, Toshiba PA3399U-1BAS Battery, Toshiba PA3250U-1BAS Battery, Toshiba PA3356U-1BAS Battery, Toshiba PA3291U-1BAS Battery, Toshiba PA3591U-1BAS Battery.


In other words, this limit shouldn't much affect most travelers because there's no limit on typical camera, cell phone, toy, and notebook batteries. So what is affected? Things like external notebook and professional videographer batteries. (I suspect that independent videographers will be one of the groups this new rule could inconvenience.)


One issue is that implementing the rule in the field is basically impossible, unless the screeners are just given some rule of thumb like "no limit on notebook batteries or anything smaller."


My notebook battery is marked only with a voltage and a milliAmp (current) rating. One can convert this to grams of equivalent lithium content (0.3 x voltage x Ah), but somehow, I don't see the screeners at security scrutinizing the label rating of batteries (when present) and whipping out calculators. So we'll have to see how notebook batteries in particular end up being counted, though I don't really expect issues around smaller camera and cell phone batteries.


There is no limit on batteries below the 100 watt-hour limit in carry-on luggage.

The other relevant part of the rule is that loose batteries are now supposed to be placed in individual plastic bags or otherwise stored in a way that their contacts can't be shorted out. It's impossible to say to what degree this will be enforced, but it's probably something else to put on your travel prep list.

Finally, I think it's worth noting that--much fevered commentary aside--this is not some new inane security rule. It's a response to lithium batteries being suspected as the cause in at least one cargo plane fire. Laptops have also burst into flames rather dramatically because of battery problems. Thus, lithium and lithium ion batteries are known to be problematic from a safety perspective.


However, it's also the case that the mobile-information age essentially runs on these batteries, and any outright ban would be incredibly disruptive. The trick, as always, is therefore to strike a reasonable balance between safety and convenience. These new rules seems to do that--at least on paper.

Fuel cell approved for use on planes

Onboard use of fuel cells, which will let notebook computers run three to 10 times longer without a recharge, has been questioned because they contain methanol, a flammable liquid.


But the DOT said that a cell designed by start-up PolyFuel can ride in airplane cabins when it emerges commercially because it contains a relatively low concentration of methanol, according to Jim Balcom, PolyFuel's CEO.


Fuel Cells are viewed as one of the likely "big" changes that will alter notebook architecture in the next few years. The replaceable, or refillable, fuel cartridges initially will be able to power laptops two to three times longer than standard laptop batteries such as Toshiba PA3383U-1BAS Battery, Toshiba PA3384U-1BAS Battery, Toshiba PA3285U-1BAS Battery, Toshiba PA3191U-1BAS Battery, Toshiba PA3166U-1BAS Battery, Toshiba PA3331U-1BAS Battery, Toshiba PA3098U-1BAS Battery, Toshiba PA3084U-1BAS Battery, Toshiba PA3399U-1BAS Battery, Toshiba PA3250U-1BAS Battery, Toshiba PA3356U-1BAS Battery, Toshiba PA3291U-1BAS Battery, Toshiba PA3591U-1BAS Battery, which now peter out at between two to four hours. Eventually, fuel cells will provide a charge 10 times longer than batteries, according to various sources.


Many analysts have viewed approval from transportation authorities as a necessary step to commercialization. If fuel cell powered notebooks can't be taken on planes, few people will buy them. It also helps psychologically.


"It is not surprising that people are hesitant, (but) once it gets approved, obviously it is viable," said Matt Sargent, notebook analyst at market research firm ARS. "There is a clear need for progress in the battery space. It has been one of the hard spots for the industry."


Air passengers, though, won't be stoking up alcohol-burning notebooks anytime soon. PolyFuel's cells remain in the development stage, and notebook makers won't likely put them in notebooks until late 2004.


"We've still got around a year and a half to go," said Balcom. "We're still in the technology development phase."


In PolyFuel's so-called eight molar methanol fuel cells, methanol, which ultimately provides the power, constitutes only 24 percent of the fluid. The rest is water.


The cells break down methanol molecules into protons, electrons and carbon dioxide. While the protons pass through a specialized membrane, the electrons can't and get shuffled into a wire that powers the device containing the cell. The by-products from the chemical reaction come together as water molecules.


Rather than completely forgo batteries, notebook makers will likely come out with computers that contain both batteries and fuel cells, said Balcom. Sanyo, among other Japanese manufacturers, has committed to coming out with fuel cell notebooks two or more years from now.


But other regulations could delay fuel cell notebooks from taking off. Airlines can independently ban certain products or devices from the cabin if they feel the objects could interfere with the handling of the aircraft, said a representative for the Federal Aviation Administration. The Department of Transportation could not be reached for comment.


Menlo Park, Calif.-based PolyFuel is a spinoff of research firm SRI Research. Investors include Intel and venture capital firm Mayfield Venture. Competitors include MTI MicroFuel Cells.

When size matters, choose small one

Welcome to a Laptop Battery specialist

Some like it big, some like it small, and others believe that there is such a thing as the right size in between. Of course, when you travel a lot, the smaller the notebook the better.


And if your work away from the office does not require desktop-class power, why not go with the tiny notebook computers called ""ultra-portable,"" ""ultra-light and ultra-thin,"" or simply ""mini-notebook.""


What distinguishes this class of notebooks from a handheld Personal Data Assistant? First and foremost, the mini-notebooks are still largely based on the Intel Architecture (IA).


This means that they still run on processors made by Intel -- or its competitor AMD. It also means that they run the full-fledged Microsoft Windows operating system -- not the Windows CE or PocketPC.


And there are also the increasingly popular Crusoe processors made by Transmeta. This processor uses software to emulate the working of the Intel processors.


We cannot expect speed from it, but Transmeta has promised that Crusoe requires so little power that a battery charge can run up to six or seven hours. In a way, Crusoe has influenced Intel to design new processors with the ability to economize in their use of battery power such as Toshiba PA3250U-1BRS Battery, Toshiba PA3356U-1BRS Battery, Toshiba PA3291U-1BRS Battery, Toshiba PA3506U-1BRS Battery, Toshiba PA3591U-1BRS Battery, Toshiba Portege 4000 Battery, Toshiba Satellite A10 Battery, Toshiba Satellite A100 Battery, Toshiba Satellite A70 Battery, Toshiba Satellite A75 Battery.


Although up to now Crusoe has not really delivered on its promise of providing many hours of computing time, at least it has brought into the picture the fact that we all want to be able to work on our notebooks for the whole day without having to look for a power outlet or an extension cord.


What is available on the market? Let us take a look at just a few of the very portable notebooks today. Toshiba has a mini notebook, Libretto, that has been around for quite many years already.


The interesting thing about the latest Libretto is that it is the first to use the Crusoe processor. With a 10-inch TFT display and a 10 GB hard disk, it runs on a 600 MHz Crusoe. It weighs only 2.4 pounds.


Sony's second generation VAIO PictureBook, a small notebook with a digital camera, has been around for a couple of years, too, although not as long as the Libretto. It runs on a 667 MHz Crusoe processor, has an 8.9-inch screen and weighs only 2.2 pounds.


Casio is a name we would readily associate with calculators and the Cassiopeia PDAs. Recently, Casio launched its own mini-notebook in the U.S., and it was called Fiva. Fiva is not to be taken lightly, though, as this 600 MHz Crusoe-powered computer comes complete with a PC-Card slot, a 20GB hard disk, a FireWire, a CompactFlash and a USB ports. It also has a built-in 56 Kbps modem and an Ethernet adapter.


Small dimensions mean a lot of sacrifices, unfortunately. The screen is very small. We cannot really write a thriller using a mini-notebook. It also comes with a small keyboard. However, as they run Windows, you can run Windows-based applications and make simple changes to your presentations or memos as you travel.


As with other electronic gadgets that you plan to buy and use for some time, the same rule applies: Try it out before you hand over your credit card. The rule becomes even truer in the case of the mini-notebooks, which are definitely not for everyone.

How to make your personal computer boot up faster

Welcome to a Laptop Battery specialist

Why boot up? Michael G., a long-time friend of mine, recently went to Singapore to get himself a gorgeous Toshiba Portege. Powered by a Mobile Pentium running at 300 MHz, the machine was quite zippy. Michael then started installing tons of utilities and drivers, including Norton Utilities and Zip Drive utilities. A couple of days later, he called me andcomplained, ""This notebook is now very slow.""


He complained that the screen painted very slowly, almost one line at a time. It was like staring at the screen of a 286 machine that ran Windows 95 with only 4 MB of RAM. Had the processor really lost its power? Was the system damaged in any way? Michael wanted to make sure. I figured, however,that what he perceived as a significant decrease in the notebook's speed was actually the long boot-up time.


When the machine first came out from the factory, it was a clean one. There were probably just a few programs that would be loaded automatically each time he booted it up or restarted Windows. Once additional utilities and drivers were installed, the computer had to load each of them before itwas ready for him to launch his productivity tool--such as Microsoft Word.


I told Michael to check the StartUp folder in his system, and my suspicion was confirmed. He had more than a dozen items on the list in the folder. This meant that each time his notebook--fast as it was--had to loadmore than a dozen programs and utilities before it handed control over to him. In the process, while the computer was busy loading the programs, the data that went to the screen also trickled, giving him the impression that the machine had lost its breath.


The StartUp Folder


It is really recommended to keep the list of programs that Windows has toload during the boot up process to the minimum, particularly if you have a notebook. That way, you will be able to start working right away once it ispowered up, and this will also save battery power such as Toshiba PA3250U-1BRS Battery, Toshiba PA3356U-1BRS Battery, Toshiba PA3291U-1BRS Battery, Toshiba PA3506U-1BRS Battery, Toshiba PA3591U-1BRS Battery, Toshiba Portege 4000 Battery, Toshiba Satellite A10 Battery, Toshiba Satellite A100 Battery, Toshiba Satellite A70 Battery, Toshiba Satellite A75 Battery. If you do not use your Zip Drive all the time, its utilities need not be loaded. If you do not useOffice Shortcut bar (and, to tell the truth, very few of us do), just throwit away.


How do you access the StartUp folder? Click on Windows' Start button, click on Settings and then Taskbar & Start Menu. The Taskbar Properties dialog box will appear. Click on the Start Menu Programs tab, and then on the Advanced button. You will get an Explorer-like dialog box as shown in the accompanying picture. Click on the Programs folder on the left pane. When the list of the subfolders appears, click on StartUp (you may have to scroll down a little if your menu list has grown quite long). Once StartUp is selected, you can see the contents on the right pane.


The list that you see under StartUp is basically the list of programs andutilities that Windows automatically load each time it starts. Some of themhad better be there. Acrobat Reader, for example, is necessary if you oftendownload and read PDF files off the Internet. My system has QuickShelf 95 on the list because I use Microsoft Bookshelf 95 quite a lot (I like its dictionary, thesaurus and encyclopedia).


A lot of other programs also like to add their own shortcut icons on the System Tray, believing that we will need them and use them. If you do not send or receive phone calls with your PC and modem, there is no reason to include in the StartUp list the answering machine utility that comes with your modem.
