our electronics

HP nixed the VIA C7-M processor it used in the 2133 Mini-Note for Intel’s reliable and power-efficient 1.6-GHz Atom N270 processor. Along with 1GB of RAM, the Mini 2140 provided the typical netbook performance we’ve seen in many similarly configured systems. We couldn’t run our usual PCMark05 test on the system, but in our hands-on experience, the machine’s Windows XP performance was snappy. Firefox and Windows Media Player opened quickly, and we saw no performance hit when conducting video calls over Skype, surfing the Web with multiple tabs open, and writing this review in Microsoft Word 2007.

The Intel GMA 950 integrated graphics chip with 64MB of memory delivered a score of 748 in 3DMark03 and 125 in 3DMark06; the former is about 70 points below the category average, and the latter is about 130 points below average. Still, the Mini 2140 scored higher on 3DMark06 than the ASUS Eee PC 1002HA (678) and the hp 372772-001 battery Samsung NC10 (730). Watching an episode of Heroes using an external DVD drive at full-screen was smooth.

Hard Drive Performance
The Mini 2140’s 160GB, 5,400-rpm Hitachi SATA hard drive (which is protected by HP’s 3D DriveGuard accelerometer) booted Windows XP Home in 57 seconds; that’s a few seconds better than the average netbook. The LAPTOP Transfer Test (copying a 4.97GB folder of mixed media) took a speedy 5 minutes and 22 seconds, a rate of 15.8 MBps. This is higher than the category average of 13.2 MBps and right smack hp 417066-001 battery between the Lenovo IdeaPad S10’s 17.4 MBps and the Samsung NC10’s 12.4 MBps. As with the HP Mini 1000, the Mini 2140 will also be available with a solid-state drive option.
Ambient Heat
Compared with the 2133 Mini-Note, which got extremely warm during heavy usage, the Mini 2140 stayed relatively cool. The keyboard and touchpad remained at room temperature during frequent use. However, the bottom of the Mini 2140 got slightly warmer than the rest of the system, registering 96 degrees during our battery test.

Battery Life
The HP Mini 2140 outshines not only its predecessor when it comes to endurance but all other netbooks equipped with six-cell batteries. On the LAPTOP Battery Test (continuous Web surfing over Wi-Fi), the system lasted a very impressive 7 hours and 19 minutes. This runtime blows away the mini-notebook average of 3:48, and it beats out even the Samsung NC10, the longest-lasting mini-notebook to date, by 45 minutes. If you can live with the added bulk of the six-cell hp 367759-001 battery, it’s more than worth the $30 premium. Still, the smaller three-cell battery lasts a solid 3 hours and 32 minutes.

HP also includes its Fast Charge technology in the Mini 2140, which can charge the netbook’s primary battery up to 90 percent within 90 minutes when the system is off. A completely drained six-cell hp f2024a battery on the Mini 2140 took 98 minutes to charge up to 98 percent with the system powered down; by comparison, the ASUS Eee PC 1000H (also with a six-cell battery) recharged up to 84 percent in the same amount of time

Kindle owners rejoice: Amazon announced an upgrade and an add-on that should please current owners of the device and tempt a few more consumers into the fold.

Kindle engineers have been hard at work on a firmware upgrade that will increase the life of the device when wireless is turned on. Instead of lasting four days, Kindle will now last 7 — an 85% increase. Battery life with wireless off remains around 2 weeks.

Amazon is also adding a native PDF viewer. Now Kindle owners don’t need to convert PDFs to Kindle files in order to read them on the device. This works for both files loaded via the USB cable from the D5318 or those emailed to @Kindle.com addresses.

These updates will come via an automatic Whispernet update for current Kindle owners.Inspiron 6000 battery，Inspiron 9300 battery，Inspiron 9400 battery.

Mary Lou Jepsen and her team at start-up Pixel Qi have their display-screen technology in several products being shown at the International Consumer Electronics Show (CES) and plan to put a DIY (do it yourself) screen kit on the market early this year.

Jepsen, formerly the head of Intel’s display division and chief technology officer at One Laptop Per Child (OLPC), has focused on lowering the battery drain by LCD screens and making them useful as e-readers in addition to normal computer use.

The GK479 company’s first screen, at 10.1-inches, is being displayed by several companies at CES, including in a multi-touch tablet PC from Notion Ink Design Labs called the Smartpad.

Pixel Qi also hopes to make the screen, called 3qi, available to anyone with some engineering savvy who wants to use its DIY kit to switch out their own netbook screen or try to create their own computer.

“We just think it’s important to give everyone an opportunity to innovate, especially [considering] our roots at One FK890 Per Child,” Jepsen said in an interview at CES, “so we’ll be announcing soon a way people can just buy the screens and mod their own notebooks or make their own systems.”

Pixel Qi hopes to have DIY kits out by the end of the first quarter or early in the second quarter of this year, she said.

Jepsen’s goal is to extend the battery life of laptops to 20 to 40 hours by lowering power consumption by the display screen. She said production of the new screens will ramp up quickly in coming Inspiron 1721 battery months.

The initial 10.1-inch screen uses LCD technology so it matches current manufacturing procedures, yet costs less to make than traditional LCDs and uses about a tenth of the power.

The screens are designed so people can read them in direct sunlight, turn off the LED backlight to view black and white text, like an e-reader, and offer a fully saturated HDTV-quality color mode for video.

Pixel Qi used Lenovo Ideapad netbooks at their CES suite to show off the black-and-white Inspiron 1720 battery mode because the LED backlight on the Ideapad can be turned off, a feature few netbooks offer.

Kyocera Wireless has issued a recall of cell phone batteries used in one of its smart phones after discovering the batteries can explode, the company said Friday in conjunction with the U.S. Consumer Products Safety Commission.

The Kyocera 7135 Smartphone has been sold with PowerBook G4 15 battery manufactured in Hong Kong that “can short-circuit and erupt with force or emit excessive heat, posing a burn hazard to consumers,” Kyocera says in a release.

The phones were sold through Verizon Wireless, U.S. Cellular, and Alltel, as well as through other retailers and Web sites from September 2003 to December 2003, Kyocera says. The A1175 batteries have “Kyocera” written in red and white on the front of the battery, and contain a product code that ends with “-05,” the San Diego company says.

Customers Warned
Kyocera instructed any users of the 7135 phones bought during that period to immediately stop using the A1045 batteries sold with those cell phones, or any batteries purchased separately from the phones during that time period.

The company plans on contacting those who purchased the battery in order to deliver a free replacement MacBook Pro 15 inch battery, but asked any customers who do not hear from the company by February 6 to call (800) 349-4478 between 6 a.m. and 6 p.m. Pacific Time Monday through Friday to obtain their replacement battery.

Nokia dealt with several incidents of exploding A1078 batteries last year, but blamed those problems on users who installed counterfeit batteries in their phones.

Over the course of a month, I ordered six batteries for my two notebooks and tested them out (see “How I tested” ). Two came from Laptops for Less, two came from Laptop Battery Express, and one battery each came from Apple Inc. and Lenovo Group Ltd. With one exception — a dead battery from Lenovo, which the company quickly replaced — each of the new batteries worked perfectly and powered up the notebooks completely.

Without a doubt, aftermarket batteries are a good way to replace a dead battery without spending a lot of money. Despite costing $20 to $70 less, the aftermarket replacements proved to be just as good and reliable as the originals in my tests.

All of the aftermarket Y9943 batteries I looked at fit fine. They just snapped in, and the systems powered right up. And the aftermarket replacements powered the notebooks for about the same amount of time per charge as the reseller replacements did.

Other than some minor cosmetic differences — for instance, the plastic on one R50 replacement was a slightly different shade of black and not as shiny as the original — I couldn’t tell them apart from the manufacturers’ batteries.

“It’s hard to tell them apart,” says BCC Research’s Saxman. “Often, notebook makers buy batteries made by a third-party manufacturer, while aftermarket battery packs frequently come from the same factory that made the originals. It’s confusing, to say the least.”

Frequently, the only things that separate the two types of Inspiron 630m battery are whose name is on the label and how much it costs. In fact, the MacBook Pro battery that Laptop Battery Express sent me was actually an Apple-branded battery with all the markings, including a serial number.

The company’s supplier said it was left over from a production run made for Apple. Whether this violates agreements between the factory and Apple is for their lawyers to fight about. All I know is that I got a battery for $30 less that appeared to be identical and gave me no problems.

Sometimes aftermarket batteries are even better than the originals. Due to added efficiencies that manufacturing plants have developed in the time since the notebook and its first battery pack were made, some replacement cells can be lighter or contain more capacity.

Two of the six batteries I looked at stand out. The MacBook Pro Inspiron 640m battery from Laptops for Less weighs 2.3 oz. less than Apple’s battery but delivers about the same capacity; it ran for only five minutes less than the reseller replacement. Then there’s the R50 replacement battery sold by Laptop Battery Express, which has a higher capacity but weighs 0.2 oz. less; it ran for an extra 10 minutes.

View popular science reading matter in one’s childhood, it is OK that understanding arrives contain through training small white rat to be in of roller basket in run toward a direction move undertake the society provides electric energy generating electricity will be future, feel very fancy. Nevertheless this is imagined and the newest originality photograph of industry is compared, be about inferior much. To make notebook computer wins longer power source support, industry invented a kind of patent technology: Clavier charger.

Clavier charger

The conception of clavier charger is: Assemble many magnet go up in clavier key-press, assemble group of hair electrical wiring in key-press on, when clavier of knock of the person that use, magnet moves in coil, generation is faradic, cell is used after these voltaic courses are changed charge. The energy of the knock clavier that allegedly these collect, can use cell time to grow 20% above. Say a fun word, the proposal should make up in case of its notebook computer last bulb, which days of power cut or there can be clavier to come when road taking night illume, this ability calls ” hand report truly ” .

Energy-saving a requirement that is jotter

Although 386 computer are done not have the driving 3D of computer is mixed now multimedia function, the point of view of the sources of energy that Dan Congwen word processing needs to use up will tell, it wants energy-saving much.

A coating on windows or solar panels that repels grime and dirt? Expanded battery storage capacities for the next electric car? New Tel Aviv University research, just published in Nature Nanotechnology, details a breakthrough in assembling peptides at the nano-scale level that could make these futuristic visions come true in just a few years.

Operating in the range of 100 nanometers (roughly one-billionth of a meter) and even smaller, graduate student Lihi Adler-Abramovich and a team working under Prof. Ehud Gazit in TAU’s Department of Molecular Microbiology and Biotechnology have found a novel way to control the atoms and molecules of peptides so that they “grow” to resemble small forests of grass. These “peptide forests” repel dust and water — a perfect self-cleaning coating for windows or solar panels which, when dirty, become far less efficient.

“This is beautiful and protean research,” says Adler-Abramovich, a Ph.D. candidate. “It began as an attempt to find a new dell laptop battery cure for Alzheimer’s disease. To our surprise, it also had implications for electric cars, solar energy and construction.”

As cheap as the sweetener in your soda

A world leader in nanotechnology research, Prof. Gazit has been developing arrays of self-assembling peptides made from proteins for the past six years. His lab, in collaboration with a group led by Prof. Gil Rosenman of TAU’s Faculty of Engineering, has been working on new applications for this basic dell inspiron 1525 battery science for the last two years.

Using a variety of peptides, which are as simple and inexpensive to produce as the artificial sweetener aspartame, the researchers create their “self-assembled nano-tubules” in a vacuum under high temperatures. These nano-tubules can withstand extreme heat and are resistant to water.

“We are not manufacturing the actual material but developing a basic-science technology that could lead to self-cleaning windows and more efficient energy storage devices in just a few years,” says Adler-Abramovich. “As scientists, we focus on pure research. Thanks to Prof. Gazit’s work on beta amyloid proteins, we were able to develop a technique that enables short peptides to ’self-assemble,’ forming an entirely new dell inspiron 1526 battery kind of coating which is also a super-capacitor.”

As a capacitor with unusually high energy density, the nano-tech material could give existing electric batteries a boost — necessary to start an electric car, go up a hill, or pass other cars and trucks on the highway. One of the limitations of the electric car is thrust, and the team thinks their research could lead to a solution to this difficult problem.

“Our technology may lead to a storage material with a high density,” says Adler-Abramovich. “This is important when you need to generate a lot of energy in a short period of time. It could also be incorporated into today’s lithium dell inspiron 1720 battery,” she adds.

Window Cleaner a thing of the past?

Coated with the new material, the sealed outer windows of skyscrapers may never need to be washed again — the TAU lab’s material can repel rainwater, as well as the dust and dirt it carries. The efficiency of solar energy panels could be improved as well, as a rain shower would pull away any dust that might have accumulated on the panels. It means saving money on maintenance and cleaning, which is especially a problem in dusty deserts, where most solar farms are installed today.

The lab has already been approached to develop its coating dell inspiron 1721 battery technology commercially. And Prof. Gazit has a contract with drug mega-developer Merck to continue his work on short peptides for the treatment of Alzheimer’s disease — as he had originally foreseen.

High-performance energy storage technologies for the automotive industry or mobile phone batteries and notebooks providing long battery times — these visions of the future are being brought one step nearer by scientists from Graz University of Technology.

Researchers at the Institute for Chemistry and Technology of Materials have developed a new method that utilises silicon for lithium-ion batteries. Its storage capacity is ten times higher than the dell inspiron 1501 battery,dell inspiron 1520 battery graphite substrate which has been used up to now, and promises considerable improvements for users.

The new findings — which came to light in the “NanoPoliBat” EU project — have been recently submitted to the patent office by researchers together with their co-operation partner Varta Microbattery.

Modern electronic devices need more energy and even the automotive industry is hankering after increasingly powerful energy storage systems. The technological development of battery research has been inadequate for some time now. “A real revolution is needed for the development of the next generation. We need new storage materials for lithium-ion batteries,” explains dell laptop battery ,dell inspiron 1521 battery researcher Stefan Koller, who is familiar with the topic from his doctoral thesis. Together with colleagues from science and industry, he has managed to develop such a substrate material for electrochemical reactions at a low price.

Silicon gel on graphite

In the newly developed process, researchers utilise a silicon-containing gel and apply it to the graphite substrate material. “In this way the graphite works as a buffer, cushioning the big changes in volume of the silicon during the uptake and transfer of lithium ions dell inspiron 1100 battery,” explains Koller.

Silicon has a lithium-ion storage capacity some ten times higher than the up-to-now commercially used graphite. The new material can thus store more than double the quantity of lithium ions without changes to the battery lifetime.

This method is far cheaper than the previous ones in which silicon is separated in the gas phase. The challenge lies in the poor storage density of materials in the counter electrode in the whole dell inspiron 1150 battery,dell inspiron 1300 battery,dell inspiron 1420 battery, something which we have been doing intensive research on,” says Koller.

Waste batteries harm to the environment has been well known to the general public. In recent years, many city schools, communities and businesses have joined the ranks of pollution prevention and control of waste batteries were, and even the kindergarten children also participated in the recovery of used batteries. However, the contrast recent State Environmental Protection Administration and other relevant departments jointly issued the “Waste Battery Pollution Prevention and Control Technology Policy,” city in the recycling of waste batteries that there are three “errors”, has come a long “detour . ”
    Mistakes do not have recycling in the recovery of
    No Recycling: No mercury batteries, button batteries and low-mercury batteries
    Key recovery: Nickel-cadmium batteries, nickel hydrogen batteries, lithium-ion batteries, lead-acid asus laptop battery and other rechargeable batteries discarded
    Not long ago, Haishu District, a primary waste battery recycling box, the reporter discovered the concentration of the various types of scrap batteries: mercury-free batteries, button batteries and low-mercury batteries, and so on. In fact, the majority here simply do not need to waste battery recycling.
    Battery of harmful substances include heavy metals and acid, alkali and other electrolyte solution. Heavy metals include mercury, cadmium, lead, nickel, zinc, mercury, cadmium, lead on the environment and human health have greater hazards, zinc, nickel in the environment more than a certain amount will also constitute a hazard to human health. Waste acid, waste alkali and other electrolytes may contaminate the soil, so soil acidification or alkalization.
    To this end, the state used batteries pollution prevention technology policy states: focus on the collection of waste batteries Nickel-cadmium batteries, nickel hydrogen batteries, lithium-ion batteries, lead-acid batteries such as rechargeable batteries and waste silver oxide button discarded disposable batteries. In the current absence of an effective recovery technique conditions, do not encourage countries to focus the collection has reached a low mercury or mercury-free scrap disposable batteries required.
    It is understood that mercury-free batteries, Ningbo, the market has reached a very high level. City’s total annual sales of all kinds of asus a31-s5 battery is about 17 million, of which the Bank of the battery company’s “Deer” batteries accounted for about 70% of the total market. At present, the Bank has the full realization of the battery cell manufacturing mercury-free. And so is estimated that the city marketing of mercury-free batteries compared to 80%. In other words, Ningbo, producing most of the waste batteries do not recall.
    Mistakes of two of the incineration landfill recovery
    Hazard: The burning of cadmium, mercury, lead battery waste can cause serious air pollution
    Reporter visited found that, at present, the city a lot of waste batteries into the municipal solid waste, with the solid waste landfill or incineration.
    Waste batteries metal mercury, cadmium, arsenic and zinc in the incineration volatile, burning into the latter part of the bottom ash, some were smoke away, encountered the cold air condensing into uniform small grain tilting. Part of the metal in the furnace involved in the reaction of chlorides, sulfides, or oxides, volatile gasification more than the original metal, the final number of these substances into the bottom ash residue, so that the heavy metal content of ash increased, difficult to handle. Therefore, incineration of cadmium, mercury, lead asus a31-s6 battery waste can cause serious air pollution, heavy metals, high levels of ash accumulation can also become heavy metal pollution.
    Relevant experts believe that mercury-free batteries can be used for landfills, incineration can also be carried out and will not pose a pollution of the environment.
    The information from the City Sanitation Department, that I am the urban areas of about 1,200 tons of garbage produced, of which 870 tons destined for Fenglin garbage disposal incinerator burning. At present, Fenglin incineration plant is no way of sorting garbage handling, waste mixed with garbage along the battery also burned. Being burned in waste batteries, there are many there must be recovered without the recovery of hazardous batteries.
    Misunderstanding of the three ring ring collection network is out of touch
    Problem: the city has yet to form an effective collection of channels, receiving waste batteries is currently nowhere to go
    Battery recycling has became a focus of public concern. But the battery recycling the outcome was in doubt.
    Battery recycling at present purely for the public conscious environmentally friendly behavior. It can be said that the city has not yet formed an effective channel for the collection of used asus a32-a8 battery. Not to mention a lot of communities, government agencies are not yet carry out this work, the collection of waste batteries and some schools closed or no answer. Reporters recently visited a residential district also found that the district had in the collection of waste batteries, but now it no more.
    Through a telephone interview, the reporter also found that the current is not responsible for the environmental protection departments to receive used batteries. Sanitation sector was unable to sort of scrap batteries, scrap batteries currently receiving nowhere to go. Fenglin is currently only enterprise-incineration plant of waste batteries will be buried in the “concrete coffin.” It can be said that the public enthusiasm for recycling of waste batteries is almost down the drain.
    According to reports, used batteries are solid wastes, including spent nickel-cadmium batteries, mercury waste batteries and waste lead-acid batteries are hazardous wastes.
    Experts analyze that in order to solve the problem of pollution of waste batteries, government departments must be correct guidance, from every community, schools, enterprises and institutions since the separate collection of hazardous waste batteries, and then transported to Fenglin incineration plant sanitation sector sealed landfill disposal. The only way to fundamentally eliminate the environmental pollution caused by used asus a32-m9 battery,asus a32-s5 battery，asus a32-s6 battery，asus a33-m9 battery.
