  Samsung Go N310 Review

  Electronics Comments Off

  Of course, what makes this version of the Samsung Go different from the unlocked version is that for $199 (plus monthly data charges) you get access to AT&T’s 3G network. It costs $35 per month if you go with the 200MB plan, but the more practical 5GB plan (particularly if you like to go to bandwidth-heavy sites such as YouTube) costs $60 per month. In addition to allowing for a more realistic amount of data per month, the 5GB plan includes a battery charge of 5 cents for every megabyte you go over the limit; with the 200MB plan, that overage charge is 10 cents per megabyte.

  Using Speedtest.net, we tested AT&T’s 3G network’s speeds from within our Manhattan office. We saw an average download speed of 1.1 Mbps, and an average upload speed of 170.0 Kbps (or about 0.2 Mbps). That download speed isn’t quite as fast as the HP Mini 311 on Verizon Wireless’ network, which fell between 1.2 and 1.3 Mbps. Its upload speeds were slower, too; the Mini 311 hovered between 500 and 600 Kbps (or, about 0.6 Mbps).

  Anecdotally, our connection over AT&T was relatively slow. Even though we had all but one bar of service, it still took 15 seconds to load ESPN.com, 40 seconds to load Laptopmag.com, and 23 seconds to load NYTimes.com. The HP Mini 311, Sony,meanwhile, loaded the same sites in 16, 11, and 11 seconds, respectively.
  Battery Life and Wi-Fi
  While the first Samsung Go unit we tested had a six-cell battery that lasted 8:23 on a charge, the version sold through AT&T comes with a smaller four-cell battery, which delivers much shorter battery life. With Wi-Fi enabled, this Go lasted just 2:47 on our Web surfing test; that time dropped to 2:42 once we logged on using 3G instead.
  While it’s nice to know the 3G connectivity doesn’t seem to significantly affect battery life, less than three hours for a netbook is unacceptable, especially when the average one lasts over five hours. Having always-on connectivity might make a netbook more mobile, but this smaller battery certainly counteracts that. AT&T would have a much stronger product if it sold the Go with a six-cell battery, offering both ubiquitous Internet access and long Sony VGP-BPS2 life.

  The Go’s wireless 802.11b/g radio delivered throughput of 19.6 Mbps and 13.1 Mbps at 15 and 50 feet, respectively. While that’s weaker than the average (20.8 and 17.1 Mbps), we found that even in an apartment where three laptops were already Sony VGP-BPL2 competing for bandwidth from our wireless-G router, the Samsung Go held its own; we didn’t experience any pauses while streaming a five-minute YouTube clip.
  Energy Efficiency
  The Go took 1:14 to charge to 80 percent, and 2:13 to completely recharge. During this time, it consumed a total of 4096.4 watts. By dividing the Sony VGP-BPS2A life by the total watts, we were able to derive the LAPTOP Battery Efficiency Rating, which came out to 24.5 (lower scores are better in this case). Given that the average netbook we test has an energy efficiency index of 16.8, that’s not terribly green. However, the Go’s EPEAT rating is 21 (out of 27), which is good.

  5 Ways to Add 4 Hours of Battery Life

  Electronics Comments Off

  It’s no secret, the Palm Pre chugs battery like an SUV burns fuel. During our own tests, we noticed that it could barely make it through the workday and other users are reporting about 8 hours of up time even without heavy usage. Proud Pre owner Tom Humplik helped us come up with a few tweaks to help keep your Pre juiced for a full 12-16 hour day under moderate usage.

  1. Turn down the brightness
  The Pre’s screen is crisper than a cucumber in May and it looks gorgeous with the brightness hiked to full, but doing so will kill your battery. Turn down the brightness and tell your Pre to idle more.

  Open the main menu.
  Find the “Screen & Lock” icon and click it.
  Under “Brightness,” Sony VGP-BPS9,pull the toggle all the way to the left.
  Change the default “Turn off after” setting from 2 minutes to 30 seconds.
  Read on for more tips on how to save battery life on your Palm Pre.
  2. You’re not lost! Turn off the GPS
  Leaving your GPS on will hog your battery life. And if you really are lost, battery life is even more important. Plus, you can always use Google Maps since it takes advantage of triangulation and doesn’t require the GPS chip to work.

  Open the main menu.
  Open Location Services.
  Under “Use GPS” move the toggle from “On” to “Off.”
  3. Sign out of your Sony VGP-BPS9/B Instant Messaging accounts.
  If you’re at the movies or at work and don’t need to be reached, sign out of your buddy lists to preserve power.

  Open the main menu.
  Click the Messaging icon.
  Click the Buddies tab up top.
  Click your green status symbol (typically next to Available).
  Choose “Sign Off.”
  4. Close unused applications
  Don’t force the Pre to multi-task if you don’t need it to. Closing out multiple applications, Sony VGP-BPS9/S,or “Cards,” can help throttle down some hardware and save juice.

  Navigate to the Pre’s desktop.
  Swipe away any cards that you don’t currently need.
  5. Throttle E-mail Auto-check
  The Palm Pre, by default, checks for new e-mail every 15 minutes. Unless you’re expecting something important during a busy work day, we suggest turning this down so that the Pre checks less frequently. Plus,Sony VGP-BPS9A, you can always manually check when you need to most.

  Open the e-mail application.
  On the top left, click the E-mail drop-down menu.
  Choose “Preferences and Accounts.”
  Click an account name.
  Under “Sync” there are two options: Show E-mail and “Get E-mail.” Click “Get E-mail.”
  Choose every “1 hour,” or longer, to preserve Sony VGP-BPS9A/B life.

  Selecting the Right Laptop for You

  Electronics Comments Off

  Perhaps no common computer product has as many variations, with as wide a performance range, as the modern laptop PC. From tiny netbooks to big and powerful desktop-replacement systems, the differences in pricing, features, and performance are staggering. Follow our comprehensive guide to make sure you get the laptop that’s right for you.

  Buying a new notebook can be tough because you have so many options to consider, and no shortage of reasons for purchasing one. Maybe you’re about to head off to college and you need to take notes in class. Perhaps your current D5318 labors when running today’s applications, and it’s time for an upgrade. Or maybe you’re happy with your desktop PC, and you want a companion device for surfing the Web from your couch. Even if you know what you want to do, with so many laptop models available it can be hard to decide among them. The potential for confusion is enough to make you choose something that just looks cool or happens to be available on your warehouse store’s shelf–but that approach can end in heartache.

  It’s best to start by deciding which category of laptop you’re most interested in. Laptops fall into four main categories: netbooks, ultraportables, all-purpose laptops, and desktop replacements. The laptop category that is right for you depends on the kind U4873 of user you are.

  Once you have decided on a category of laptop, it’s time to start considering the specs. To learn how to wade through all the product names and acronyms, check out “Laptop Buying Guide: Making Sense of the Specifications.” And before you ask the store to run your credit card, read our Inspiron 6000 battery advice in “Laptop Buying Guide: Shopping Tips.”

  Company provides details of manufacturing problem that affects millions of notebook batteries

  Electronics Comments Off

  TOKYO –Sony has provided greater detail about a battery manufacturing problem that is expected to see the replacement of up to 9.6 million laptop computer battery packs.

  What Went Wrong?
  The problem was first acknowledged in August when Dell issued a recall for 4.1 million batteries and until now had been explained as metallic particles that got into the battery during the manufacturing progress. Today Sony expanded on this and said the particles, believed to be nickel, likely got into the battery during two stages in production: when a groove was created in the battery case and when the electrolyte was poured into the cell.

  But that alone wouldn’t be enough to cause the fires that have been reported by Sony VGP-BPL2 owners. For that to happen Sony believes that the particles would have to fall into a small triangular gap in the cell body right at the point where the cathode ends between two layers of spacer material. Then, depending on system configuration, the conditions could be right for a fire to start in the battery.

  “The probability of this occurrence very much depends on system configuration,” said Takashi Enami, senior general manager of the energy business group at Sony. He said size and shape of the battery pack and the charging configuration could all increase the risk but he wouldn’t offer any specific information citing confidentiality agreements between Sony and its customers.

  Replacement Program Details
  As a result of the problems 6.1 million Sony VGP-BPS8 batteries have been recalled by Dell and Apple Computer. An additional 3.5 million batteries are covered by a Sony-led replacement program that offers new batteries to laptop users who are worried about the safety of their system. Last week Sony said it anticipates costs of $429 million as a result of the battery problems.

  The replacement program covers two types of cells used in battery packs, a 2.4Ah (ampere hour) and 2.6Ah model, and information on the affected battery packs and laptop PC models sold in the U.S. can be obtained from the U.S. Consumer Product Safety Commission.

  Sony considered the Sony VGP-BPS8A  battery replacement after a Lenovo-made laptop caught fire at Los Angeles International Airport, said Yutaka Nakagawa, executive deputy president of Sony and head of its semiconductor and component group. That incident is still under investigation and as only two of the six cells inside the battery pack remain it’s difficult to pinpoint the exact cause, he said.

  “In preparing for the program we have been in discussion with the CPSC and the PC manufacturers, which required time, and that is why the announcement is being made today,” said Nakagawa.

  Sony Will Outsource Some Replacements
  The replacement batteries won’t all come from Sony because it doesn’t have the manufacturing capacity to produce them all in the time required, said Nakagawa. As a result Sony will source some cells from rival companies. Nakagawa said as a result there is a general possibility that Sony might not win back all the business it had before the Sony VGP-BPS9 battery problems occurred. Its success or failure in keeping business very much depends on how well Sony does to persuade customers that the problems are behind it, he said.

  Additionally Sony also increased the number of its own battery packs eligible for the replacement program. Last week it said 60,000 batteries used in PCs in Japan and China would be replaced and today increased this to 250,000 batteries worldwide.

  Battery making start-up Boston Power is more than tripling production of its Sonata laptop battery

  Electronics Comments Off

  Battery making start-up Boston Power is more than tripling production of its Sonata laptop battery, a device that offers faster charging and longer life than conventional lithium-ion batteries, it is due to announce Thursday.

  Boston Power has also struck a manufacturing partnership with Taiwan’s GP Batteries, which will begin making the cells to supplement current production at China’s HYB Battery. GP will produce around 1 million cells per month, said Christina Lampe-Onnerud, founder and CEO of Boston Power. HYB currently produces between one third and one half that amount, she said.

  The Sonata PC764 battery was a hit when it was unveiled at the Demo 2007 conference in January 2007 because, according to Boston-Power, it gets over some of the main frustrations laptop users have with their battery packs. Namely it can be charged to 80 percent of total capacity in 30 minutes so even on a short lay-over a meaningful amount of power can be recharged into the battery and it should also last the average three years that people keep their laptops without a noticeable degradation in performance.

  In light of a series of high-profile problems and recalls of lithium-ion batteries, Boston-Power is also pushing safety. It says its Sonata battery uses less reactive chemicals and has a series of protective controls that make it safer than competing batteries.

  With the extra production, Boston-Power will be looking to pick up customers for the Sonata Latitude D620 battery. It has already been working closely with Hewlett-Packard.

  “We are delighted with the response from the market. Interest is really, really large” said Lampe-Onnerud. “We have worked with top-tier notebook makers for several years and they remain extremely engaged. Many have already qualified our system but we’re a small company so we have to be selective about who we work with.”

  Boston-Power has also closed a third round of financing for US$45 million, which it will announce Thursday. The round, led by Oak Investment Partners, also included additional money from existing investors Venrock Associates, C1295,Granite Global Ventures and Gabriel Venture Partners. The latest investment brings to US$68 million the total amount of funds raised by Boston-Power.

  Apple Looks to Repackage Content for Tablet

  Electronics Comments Off

  Apple is looking at ways TV, magazine and newspaper content can be presented differently on its upcoming tablet device, according to a report published in the Wall Street Journal on Wednesday.

  The company is also targeting the tablet as a gaming device, for which Apple is working with video-game publisher Electronic Arts, according to the report, which quoted people familiar with the situation.

  Apple reportedly is talking to many service providers to deliver content to the device. For magazine content, Apple is talking with companies including The New York Times, Conde Nast Publications and News Corp., the apple a1008 battery report said. Apple is also negotiating with CBS and Walt Disney to deliver monthly TV subscription services.

  Apple is reportedly also talking to HarperCollins Publishers to sell electronic books for the tablet. As part of the deal, HarperCollins will set its own price for the e-books, from which Apple will get a cut. Apple’s purchase of streaming music provider Lala.com in December has also been linked to the tablet.

  Though Apple hasn’t confirmed the device, the company has sent out invitations for a Jan. 27 launch event where the tablet is expected to be launched. The device is said to be a larger version of the iPhone with a touch screen sized about 10 inches to 11 inches and a virtual keyboard.

  Kai-Fu Lee, a former Apple employee and previously the head of Google in China, apple a1012 battery,recently blogged that the tablet would come with 3D graphics and a price tag below US$1,000.

  Battery maintainance is very important

  Electronics Comments Off

  Besides in the choose and buy when should see clear batteries size besides, in at ordinary times in using, we also want understanding how to maintain batteries!

  a netizen sends a message to say today, his IBM because this machine did not maintain goodly batteries, brought about to use the batteries that does not arrive one year to already drew near finally discard as useless. The most interesting nevertheless still be from the back, this netizen continues say, he of unwilling to give up sought all sorts of meanses that save batteries, let this batteries eventually ” renascent ” .

  Be what method after all, I am described probably. Go up from above all get off batteries, seek a piece of paper again, will already ” death ” batteries has been wrapped. Look for the plastic bag with one proper size again, the toshiba pa3191u-1brs , toshiba pa3166u-1brs  that has included paper is put in, give off the redundant air inside the pocket, with mouth of bag of pitch of line or oak adhesive plaster.

  Open the entrance door of freezer freezer compartment next, will this ” classic ” inside the refrigerant case that puts 5 degrees. After closing, patient ground awaits 72 hours, namely 3 days ah. As to the utility of newspaper, it is to absorb redundant moisture, polybag is airtight save in order to prevent external moisture is entered.

  After 3 days, take out battery, take out polybag and newspaper, 48 hours are placed below room temperature namely the 2 machine on the Queen of heaven charge. The miracle appeared later, batteries can hold to 1 hour 18 minutes 0. Very long time has been for the toshiba pa3331u-1brs, toshiba pa3399u-1brs that dies to drawing near together.

  Do not cross this ” cheat cadaver ” the process is really false after all, we still cannot decide. To the folk prescription of this kind of folk, there still is a lot of on the net, the friends that have fun at conditionally can have a try, ah.

  Be here nevertheless or teach everybody a few maintain correctly the method of batteries. Main component is the following at 4 o’clock:

  The first, avoid to discharge completely, and often charge to lithium  toshiba pa3250u-1brs , toshiba pa3356u-1brs. And charging at will repeatedly is very small to the injury of lithium batteries, almost negligible not plan.

  Dutch researcher Marianne Kox discovered the deviations in the miniscule but indispensable particles

  Electronics Comments Off

  One of the most important catalysts in the modern chemical industry is a troublemaker. The building blocks of zeolite ZSM-5 crystals, which are a sort of Swiss cheese with molecular size holes, are not joined together perfectly. The materials that have to pass through the crystals therefore often get stuck and don’t react well. Dutch researcher Marianne Kox discovered the deviations in the miniscule but indispensable particles.

  Nearly all medicines, fuels and other chemical products come into contact with catalysts at some stage of their ‘lives’. These help to convert one material, for instance crude oil, into another, such as petrol. Take a good look around and you can see the evidence of the hard work done by these catalyst particles everywhere. Marianne Kox studied one of the most important catalysts, zeolite ZSM-5 crystals. These particles look like pieces of Swiss cheese with miniscule channels through which the material that has to be converted must pass. But it seems some of the holes do not want to cooperate leading to differences within one individual catalyst particle.

  ‘Big Brother’ of catalysis

  Like a real ‘Big Brother’, Marianne Kox spied on the zeolites with a combination of different micro-spectroscopic techniques. By doing so, she managed to study the zeolite particles in a space- and time-resolved manner, for example the interior of the catalyst in 3D. She discovered why some of the zeolite crystals were not behaving properly, and how their behaviour differed from one position in the crystal to another.

  Depending on the shape of the crystals — for example a boat shape or even the shape of a coffin — the channels inside a zeolite crystal didn’t seem to run properly, and they could get blocked. This was caused by the building blocks that make up the zeolite crystals not fitting together properly. As a result of this the catalyst did not function as well as it could. Thanks to the unique combination of techniques applied by Marianne Kox, individual catalyst particles and their working principles can be studied in more detail, making improvement of the catalyst possible.

  Marianne Kox’s research is part of the Vici project run by Bert Weckhuysen. The December 2009 issue of Nature Materials contained the article Morphology-dependent zeolite intergrowth structures leading to distinct internal and outer-surface molecular diffusion barriers, about this research, to which PhD researcher Lukasz Karwacki also contributed.dell inspiron b130 battery,dell inspiron e1405 battery,dell inspiron e1505 battery,dell inspiron e1705 battery,dell latitude d410 battery,dell latitude d420 battery,dell latitude d430 battery.

  To Create an Instant Battery

  Electronics Comments Off

  Simply coating a sheet of paper with ink made of carbon nanotubes and silver nanowires makes a highly conductive storage device, said Yi Cui, assistant professor of materials science and engineering.

  “Society really needs a low-cost, high-performance energy storage device, such as batteries and simple supercapacitors,” he said.

  Like batteries, capacitors hold an electric charge, but for a shorter period of time. However, capacitors can store and discharge electricity much more rapidly than a battery.

  Cui’s work is reported in the paper “Highly Conductive Paper for Energy Storage Devices,” published online in the Proceedings of the National Academy of Sciences.

  “These nanomaterials are special,” Cui said. “They’re a one-dimensional structure with very small diameters.” The small diameter helps the nanomaterial ink stick strongly to the fibrous paper, making the dell laptop battery and supercapacitor very durable. The paper supercapacitor may last through 40,000 charge-discharge cycles — at least an order of magnitude more than lithium batteries. The nanomaterials also make ideal conductors because they move electricity along much more efficiently than ordinary conductors, Cui said.

  Bing Hu, a post-doctoral fellow, prepares a small square of ordinary paper to with an ink that will deposit nanotubes on the surface that can then be charged with energy to create a battery.

  Cui had previously created nanomaterial energy storage devices using plastics. His new research shows that a paper dell inspiron 6000 battery is more durable because the ink adheres more strongly to paper (answering the question, “Paper or plastic?”). What’s more, you can crumple or fold the paper battery, or even soak it in acidic or basic solutions, and the performance does not degrade. “We just haven’t tested what happens when you burn it,” he said.

  The flexibility of paper allows for many clever applications. “If I want to paint my wall with a conducting energy storage device,” Cui said, “I can use a brush.” In his lab, he demonstrated the dell inspiron 630m battery to a visitor by connecting it to an LED (light-emitting diode), which glowed brightly.

  A paper supercapacitor may be especially useful for applications like electric or hybrid cars, which depend on the quick transfer of electricity. The paper supercapacitor’s high surface-to-volume ratio gives it an advantage.

  “This technology has potential to be commercialized within a short time,” said Peidong Yang, professor of chemistry at the University of California-Berkeley. “I don’t think it will be limited to just energy storage devices,” he said. “This is potentially a very nice, low-cost, flexible dell inspiron 6400 battery  electrode for any electrical device.”

  Cui predicts the biggest impact may be in large-scale storage of electricity on the distribution grid. Excess electricity generated at night, for example, could be saved for peak-use periods during the day. Wind farms and solar energy systems also may require storage.

  “The most important part of this paper is how a simple thing in daily life — paper — can be used as a substrate to make functional conductive electrodes by a simple process,” Yang said. “It’s nanotechnology related to daily life, essentially.”

  Cui’s research team includes postdoctoral scholars Liangbing Hu and JangWook Choi, dell inspiron 640m battery,and graduate student Yuan Yang.

  Battery “friction failure” problem has been solved

  Electronics Comments Off

  AP minus 45 degrees Celsius in the arctic conditions, can be easy to fire from car? Spare battery is also strong and do a year? Battery acid corrosion can be no excess equipment?
  The near-dream for the demanding battery now become a reality. “Starter-type sodium high-energy batteries scientific and technological achievements” recently appraised by experts in Harbin. Chinese Academy of Engineering, DU Shan-yi, and other experts believe that the technology break the battery “friction failure” of the global problem, reached the international advanced level.

  Experts have found that the traditional acer laptop battery “internal resistance” and “within the discharge” not only unnecessary to drain the energy, but also lead to side effects such as sulfuric acid spill. Thus the invention of “salt and high-conductivity electrolyte” and “high capacity positive and negative electrode active material endurance formula and production method” two patented technology.

  After testing, the new battery capacity is not only higher than the ordinary type more than 15% more conducive to high-current discharge. Starting vehicle, sparking a row of traditional products are generally about 15 times will be failure, while the new acer aspire 5560 series battery,acer aspire 5920 battery,acer aspire 5520 battery has up to 80 times or more. Of Heilongjiang in China’s far north side of the cold polar experiments show that the average long vehicle parking at minus 40 degrees Celsius outside, still be successful ignition.
