  • AMD is crying foul over battery tests run by computer makers and consumer electronics publications, according to a report in the New York Times. The chip maker claims that the standard benchmark used, MobileMark 2007, unfairly gives an advantage to Intel CPUs.

    From the article: “Intel is advantaged in this environment because they have optimized their architecture to have better  FK890 life when the computer isn’t doing anything,” AMD’s Patrick Moorhead said.

    Well, isn’t that a good thing in general? Shouldn’t AMD be trying to make its dell chips use less power when they’re not doing anything?

    But here’s the thing: We don’t use MobileMark to test battery life, and systems with AMD chips still see worse endurance than those with Intel chips. Read on for our results.

    We took a look at seven different AMD machines we reviewed over the past several months, and how they fared on the LAPTOP Battery Test, which continuously surfs the Web over Wi-Fi until the GK479 is dead.

    In the ultraportable category, the HP dv2’s endurance was almost half the category average.Inspiron 1721 battery, Inspiron 1720 battery.

  • HP’s consumer netbook just got a makeover. We wouldn’t call it extreme, but the 2.7-pound Mini 210 is significantly different both inside and out. Like other new netbooks, this one features Intel’s latest Atom N450 processor, which has two benefits. First, the efficient CPU should help the machine get over 9 hours of battery life. Plus, the N450’s smaller package size allowed HP to create a more unified design, although the six-cell battery dips down a bit.

    And this is no ordinary-looking netbook. The Mini 210 is available four colors; the Black Crystal and Silver Crystal designs have cool Imprint patterns, and the Pacific Blue and Sonoma Red are solid colors. HP calls it a 360-degree design because these colors and patterns wrap around the entire system, which looks pretty cool. (Check out the video.)

    During our brief hands-on time with a pre-production model, we liked the chiclet-sytle keyboard on the Mini 210, which reminds us of the more business-minded Mini 5102. The touchpad couldn’t be more different,hp laptop battery , however; the buttons are integrated into the pad. In general we prefer discrete buttons, and we’re not sure this implementation will be good enough to change our mind. Read on for more details and to check out the gallery and hands-on video.

    Like the Dell Inspiron Mini 10, HP offers a ton of options to trick out your system, including a full HD display and Broadcom CrystalHD Enhanced Video Accelerator for smoother full-screen video playback on sites like Hulu. Other potential goodies include 3G broadband and GPS. (Only the Dell offers a TV tuner.)

    On the software front, HP is emphasizing the cloud and multimedia. HP CloudDrive, powered by ZumoDrive allows users to access documents, photos and music (including iTunes libraries and playlists) online. MediaStream lets users stream content form one hp pavilion dv2000 battery to another over the Web. You also get QuickSync software (for syncing files between two computers over a local network) and QuickWeb (for instant-on Web surfing, powered by Splashtop).

  • GPGPU acceleration and tessellated graphics may soon break free from the clutches of your desktop. Acer is reportedly working toward releasing the Aspire 8942G-728G1280TWN, according to Fudzilla. This 10-pound behemoth promises to work out your biceps as well as your 3D benchmark score.

    While the advances in DirectX 11 may only be noticeable to the most hardcore graphics geeks, the standard is slowly starting to penetrate the market. Acer’s new notebook is expected to pack an impressive spec sheet to go along with the DX11 graphics API. We’re talking an Intel Core i7 processor at 1.6GHz, acer btp-42c1 battery,8GB of DDR3 RAM, and not one, but two 640GB hard drives.

    On the graphics side, the reputable ATI Radeon HD5850 will be calling the shots (and frags) for gamers. And to top it all off, the Acer notebook will ship with an 18.4-inch 1080p (1920-by-1080 resolution) LED-backlit display, acer btp-43d1 battery,Blu-ray drive, 5-in-1 card reader, Bluetooth, and 8-cell battery. If you listen carefully, you can hear your laptop crying softly in shame.

    The notebook has yet to appear on Acer’s site, and we have yet to confirm the specs and availability with Acer (we’ll update this post as soon as we do), but Fudzilla says that the new PA3399U-1BRS should be on sale in early 2010.

  • An airline pilot union is calling on the U.S. government to temporarily ban cargo shipments of lithium batteries, saying they represent a serious safety hazard.

    The Air Line Pilots Association (ALPA), which represents pilots in the U.S. and Canada, asked that the U.S. government prohibit shipments of lithium batteries on all cargo and passenger flights until measures are taken to insure that such shipments are safe. The proposed ban on the batteries, which are widely used in electronic devices like phones and computers, would not prohibit passengers from carrying batteries on planes.

    “The evidence of a clear and present danger is mounting. We need an immediate ban on these dangerous goods to protect airline passengers, crews, and cargo,” said Mark Rogers, director of ALPA’s Dangerous Goods Programs,KD476, in a press release.

    During the last two months, there have been three incidents where fire or smoke on aircraft was caused by shipments of lithium batteries. Those incidents were detailed in a letter that ALPA sent to Cynthia Douglass [CQ], acting deputy administrator of the Pipeline and Hazardous Materials Safety Administration of the Department of Transportation.

    On August 14, the crew of a plane that landed in Minneapolis received a warning of smoke in the plane’s forward cargo compartment. When fire crews opened the compartment, they found flames coming from a container filled with electronic cigarettes, each containing a lithium-ion battery. In another incident in July, a container filled with lithium-ion GD761 batteries on a flight to Santo Domingo, Dominican Republic, was found smoking and smoldering.

    In the third incident, which took place in June, a burned package containing a lithium-ion bicycle motor was discovered when cargo handlers unloaded a plane in Honolulu.

    ALPA said all three incidents recall a 2006 incident where lithium TD347,Inspiron 6400 batteryInspiron E1505 battery  caused a fire on board a UPS plane that injured three crew members and damaged cargo.

  • Eight months after recalling potentially flammable notebook PC batteries, Toshiba Corp. is again urging its customers to trade in the defective units, saying one of its notebooks caught fire on May 24.

    Toshiba was one of many PC vendors that recalled more than 8 million rechargeable lithium-ion batteries made by Sony Corp. A manufacturing defect left those batteries vulnerable to short-circuiting and catching fire if they were jostled, prompting the U.S. Consumer Product Safety Commission to issue a broad recall.

    dell Inc. was the first to recall those batteries in August 2006, and was quickly followed by Apple Inc., Lenovo Group Ltd., Fujitsu Computer Systems Corp., Gateway Inc. and Sony Electronics Inc. By October 2006, that defect had led to 16 reports of notebook computer batteries overheating, causing minor property damage and two minor burns, according to the Commission.

    On Tuesday, Toshiba said the latest fire was sparked by a battery that was never returned.

    “Recently, certain instances occurred where Sony battery packs installed in Toshiba portable computers caught fire,” Toshiba said in a statement on its Web site. After an investigation with Sony, Toshiba found that the battery caused “the situation,” the statement said.

    “The original Sony Battery Pack had not been replaced as recommended by Sony and Toshiba. We put importance on the fact that the incidents that occurred involved unreplaced SonyBattery Packs, despite our ongoing replacement program.”

    In the original recall, the Commission warned laptop users to remove the batteries immediately and to power their PCs only by plugging them into a wall outlet until receiving a free replacement battery from the PC manufacturer. Laptop users were responsible for taking the initiative to return their own batteries, leading some analysts to predict that only a small percentage would do so.

    Other PC vendors may face the same challenge, although the Commission does not list any other fires. Dell is continuing to replace the faulty batteries, but a spokesman said he could not produce figures for the number of batteries replaced or whether the company had noted any overheating incidents since the recall began.

    “The recall’s going well. Customers are taking heed to send back the affected batteries and have replacements sent to them,” said Dell spokesman Bob Kaufman.

    In response to the latest fire, Toshiba warned customers to stop using the affected Sony VGP-BPS9 immediately. Users who continue running their laptops on battery power should not leave their PCs unattended while they charge and should not place PCs on a sofa, bed or other surface that could obstruct its ventilation, Toshiba said.

    Toshiba has not changed the list of laptops that use the affected batteries. They include various models of the company’s Portege, Qosmio, Satellite and Tecra brand PCs. As with the original recall, Toshiba will replace all affected batteries for free.

  • HP and Lenovo made the biggest splash in terms of notebooks during this year’s Consumer Electronics Show (CES) in Las Vegas. Lenovo, makers of the ThinkPad line of business notebooks, are determined to grab a larger market share among consumers this year.

    The new IdeaPad S10 Tablet is an Intel Atom-based netbook with a 10-inch touchscreen that rotates 180 degrees in either direction. Available with either a flush 3-cell battery or extended life 6-cell battery this netbook tablet looks like it will give the ASUS Eee PC T91 a run for the money. As we’ve come to expect with Lenovo notebooks, the keyboard on the new S10 Tablet is second to none in this form factor. The screen bezel might be large, but that was done on purpose to provide more room for the larger keyboard. The keys feel fantastic with just the right amount of throw and there is no sign of flex in the pre-production keyboard we used.

    Some Smartbooks Are Smarter Than Others
    Smartbooks, a new category of thin and light laptops that bridge the gap between a smartphone and a netbook, will probably be a major push from several manufacturers in 2010. The Lenovo Skylight was the first of these smartbooks to go public.

    Sure, the Skylight is thin and lightweight. It’s also got a great keyboard and screen. It even has the smartphone-like ability to almost instantly wake from sleep mode (a huge time saver compared to netbooks and ultraportable notebooks). However, the smartphone-like user interface just screams out for a touchscreen. The fact that user will have to control the Skylight with a standard touchpad and keyboard is probably the least smart element of this smartbook. Yes, a standard display makes the Skylight thinner, lighter, and cheaper but we’re starting to think that smartbooks, like all modern smartphones, really need to have a touchscreen.
    Thankfully, it looks like our editors aren’t alone in wanting smartbooks with touchscreens. Although HP isn’t ready to announce a touchscreen smartbook, they did have an extremely interesting smartbook prototype on display at CES this year. The yet-to-be-named HP smartbook is based on HP’s current Mini family of netbooks, but this ultraportable is thinner, lighter, and based on the Snapdragon ARM II processor just like the Lenovo Skylight. The HP smartbook prototype runs a customized version of the Google Android operating system and, more importantly, features a touchscreen like you’d expect to see on a device that’s intended to act like an enlarged smartphone.

    HP representatives were all quick to point out that this prototype may never see the light of day, but it should serve as an indication of what form factor HP thinks will work best for the smartbook category.

    Not to be outdone, Lenovo also debuted the Lenovo IdeaPad U1 hybrid netbook and slate tablet/smartbook. Our entire staff was pretty impressed with this innovative concept … and even more impressed that it’s ready for sale. The IdeaPad U1 works just like a standard Intel Atom-based netbook with a full keyboard and touchpad running Windows 7, but with the flip of a switch you can unplug the touchscreen display and you’ve got an ARM-based tablet PC ready for travel with it’s own operating system and flash storage. What makes the U1 even cooler is that you can connect the bottom half of system to an external monitor and use it as a Windows desktop PC while the top tablet portion of the laptop is being used by someone else. When you reconnect the tablet to the bottom half of the laptop then the data will automatically synchronize so that you don’t lose your work. Time will tell whether consumers want smartbooks with thin standard screens or if they’re willing to buy a slightly thicker smartbook with a touchscreen interface.

  • Electronic manufacturers should consider what truly is the heart of most of their portable devices - the battery. The size, shape, weight, and function are all directly related to the battery that will power them. The battery also provides an essential backup on printed circuits and computer systems. It seems that just about every six months a new battery technology emerges using much more exotic and expensive materials. Think about what the cell phone has become as a direct result of the size and capacity of the batteries powering them. Each successive improvement makes batteries smaller, able to hold a charge longer, and able to charge faster. This article takes a look at some of the new battery technologies and how they will improve the electronics industry.

    Latest Developments

  • Sanyo introduced the new “eneloop” battery, which is a rechargeable NiMH battery useable right off the shelf. Unlike previous rechargeable batteries, which have limited shelf life because of their rapid discharge, these batteries retain 85% of their charge even after one year. Because this battery can be used for thousands of charges and is easily recycled, it is much more convenient, cost-effective, and eco-friendly than the traditional single-use batteries.
  • Toshiba Corporation has announced a breakthrough in lithium-ion batteries that makes long recharge times a thing of the past. The company’s new battery can recharge 80% of a battery’s energy capacity in close to one minute, approximately 60 times faster than the typical lithium-ion batteries in wide use today. The battery also has a long life cycle, losing only 1% of capacity after 1,000 cycles of discharging and recharging, and can operate at very low temperatures .
  • Techtronic Industries Co. Ltd. of Hong Kong developed the V28™. This 28-volt battery delivers increased power and up to twice the run time of traditional 18-volt models, yet the battery weighs slightly less. This means the introduction of new tools like the world’s first cordless band saw powerful enough for every day professional use. Containing no cadmium, the lithium ion battery has built-in fuel gauge that tells users how much run time is available. In addition, this battery is equipped with built-in Performance Optimizing Circuit to provide consistent, fade-free power throughout discharge cycle to ensure job power consistency.
  • Panasonic Batteries has its new Digital Xtreme Power batteries with oxyride technology, designed to last twice as long as regular alkaline batteries, according to the company. They utilize a combination of newly developed materials for the cathode (plus side): Oxy Nickel Hydroxide and new technologically developed manganese dioxide and graphite. According to Panasonic, that means the batteries will yield three times as many snapshots with a digital camera, with a shorter flash recovery time.
  • Trends

    Battery Council International recently completed part of an ongoing project to determine the trends of battery development (among other things) and how manufacturers will adapt. There are a few interesting items to note from their research:

     

  • The North American volume will continue to decline due to longer life batteries.
  • Auto accessories will increase battery power needs.
  • Government regulations and restrictions will become more stringent
  • Lead-acid batteries will lose share in the car industry due to increased use of Lithium and Nickel batteries
  • Market demand for rechargeable batteries will increaseVarious forms of lithium batteries are emerging on the market. Although there are concerns about their flammability, many manufacturers are pushing industry standards by pre-qualifying these battery makers. The reason for this trend is simple - lithium is the lightest metal, which results in a high specific charge. For example, it takes 3.85g of lead to produce 1 amp for 1 hour while it only takes 0.26 grams of lithium to produce the same. One type of lithium battery is only 2.5mm. Lithium also produces a higher voltage and therefore, a higher energy density. Lithium is also more eco-friendly than lead or cadmium. These characteristics seem to fit right in line with market trends and many electronics manufacturers have noticed. dell 6y270 battery,dell 75uyf battery,dell c1295 battery,dell gd761 battery,dell kd476 battery,dell td347 battery,dell u4873 battery,dell d5318 battery,dell g5266 battery.

  • There’s one major drawback to most proposed renewable-energy sources: their battery variability. The sun doesn’t shine at night, the wind doesn’t always blow, and tides, waves and currents fluctuate. That’s why many researchers have been pursuing ways of storing the power generated by these sources so that it can be used when it’s needed.

    So far, those solutions have tended to be too expensive, limited to only certain areas, or difficult to scale up sufficiently to meet the demands. Many researchers are struggling to overcome these limitations, but MIT professor Donald Sadoway has come up with an innovative approach that has garnered significant interest — and some major funding.

    The idea is to build an entirely new kind of battery, whose key components would be kept at high temperature so that they would stay entirely in liquid form. The experimental devices currently being tested in Sadoway’s lab work in a way that’s never been attempted in batteries before.

    This month, the newly established federal agency ARPA-E (Advanced Research Projects Agency, Energy) announced its first 37 energy-research grants out of a pool of 3,600 applications, and Sadoway’s project to develop utility-scale batteries received one of the largest sums — almost $7 million over five years. And within a few days of the ARPA-E announcement, the French oil company Total — the world’s fifth-largest — announced a $4 million, five-year joint venture with MIT to develop a smaller-scale version of the same technology, suitable for use in individual homes or other buildings.

    Because the technology is being patented and could lead to very large-scale commercialization, Sadoway will not discuss the details of the materials being used. But both Sadoway and ARPA-E say the sony vgp-bps11 battery is based on low-cost, domestically available liquid metals that have the potential to shatter the cost barrier to large-scale energy storage as part of the nation’s energy grid. In announcing its funding of Sadoway’s work, ARPA-E said the battery technology “could revolutionize the way electricity is used and produced on the grid, enabling round-the-clock power from America’s wind and solar power resources, increasing the stability of the grid, and making blackouts a thing of the past.”

    Andrew Chung, a principal at Lightspeed Venture Partners in Menlo Park, Calif., which has no equity stake in Sadoway’s project at this point, says that “grid-scale storage is an area that’s set to explode in the next decade or so,” and is one that his company is following closely. The liquid battery concept Sadoway is developing “is an exciting approach to solving the problem,” he says.

    Big is beautiful

    Most battery research, Sadoway says, has been aimed at improving storage for portable or mobile systems such as cellphones, computers and cars. The requirements for such systems, including very low weight and high safety, are very different from the needs of a grid-scale, fixed-location sony vgp-bpl11 battery system. “What I did was completely ignore the conventional technology used for portable power,” he says. The different set of requirements for stationary systems “opens up a whole new range of possibilities.”

    A large, utility-owned system “doesn’t have to be crash-worthy; it doesn’t have to be ‘idiot-proof’ because it won’t be in the hands of the consumer.” And while consumers are willing to pay high prices, pound-for-pound, for the small batteries used in high-value portable devices, the biggest constraint on utility-sized systems is cost. In order to compete with present fossil-fuel power systems, he says, “it has got to be cheap to build, cheap to maintain, last a long time with minimal maintenance, and store enormous amounts of energy.”

    And so the new liquid batteries that Sadoway and his team, including graduate student David Bradwell, are designing use low-cost, abundant sony vgp-bps13 battery materials. The basic principle is to place three layers of liquid inside a container: Two different metal alloys, and one layer of a salt. The three materials are chosen so that they have different densities that allow them to separate naturally into three distinct layers, with the salt in the middle separating the two metal layers —like novelty drinks with different layers.

    The energy is stored in the liquid metals that want to react with one another but can do so only by transferring ions — electrically charged atoms of one of the metals — across the electrolyte, which results in the flow of electric current out of the battery. When the battery is being charged, some ions migrate through the insulating salt layer to collect at one of the terminals. Then, when the power is being drained from the sony vgp-bps13/b battery, those ions migrate back through the salt and collect at the opposite terminal.

    The whole device is kept at a high temperature, around 700 degrees Celsius, so that the layers remain molten. In the small devices being tested in the lab, maintaining this temperature requires an outside heater, but Sadoway says that in the full-scale version, the electrical current being pumped into, or out of, the battery will be sufficient to maintain that temperature without any outside heat source.

    While some previous battery technologies have used one liquid-metal component, this is the first design for an all-liquid battery system, Sadoway says. “Solid components in batteries are speed bumps. When you want ultra-high current, sony vgp-bps13a/b battery,sony vgp-bps13b/b battery,compaq laptop battery you don’t want any solids.”
