Battery life of iPod is an important consideration to most iPod users. The laptop battery degrades over time and are not easily changed by users. That is true, to a point, as the lithium battery is based, although that can be recharged up to 500 times, it degrades over time.

Mean that the iPod Nano 8GB was designed to be a disposable device? No. Apple has designed the iPod Nano 8GB last long.

The battery life is only a few years, since it is based lithium also the 9Cell 6000mAh Apple Macbook Pro 13 inch battery life is only 13 months . This network of hundreds of users of the charges, however, at some point, the lithium battery will stop working. An iPod battery is not designed to replace users.

This is because the battery is soldered on the iPod. The problem does not change the iPod battery does not last long though, according to market experts took advantage of the situation and offered the owners of the iPod Nano 8GB replacement battery alternative, which includes instructions on how to remove the old battery and insert new one. The owners of the iPod Nano 8GB can choose to send your device to Apple to replace iPod battery.

In addition, Apple offers on its website users tips on keeping your battery. The following tips and tricks will ensure that your battery last longer: An iPod Apple A1079 battery works best when the iPod Nano 8GB is a temperature between 0-35 C (32-95 o F).

Never leave your iPod Nano 8GB in a car. We must not let your iPod to direct sunlight. When unattended, Press the break. Anytime you are not using your iPod, slide the HOLD button.

Your iPod will continue to play if the pause button is not pressed. This can significantly affect the life of the iPod Apple A1078 battery. Most times, it will require re-lighting.

This function uses much of the reserved battery power. If it is not absolutely necessary, turn it off. Select Settings> Back Light Timer> Off. You should be aware that even when you’re not using your iPod, the battery is still working.

While your iPod Nano 8GB is sleeping, the Apple A1061 battery is fully conscious, and loses a small amount of current. By ensuring that the iPod is used and stored at room temperature, which can significantly limit the amount of battery power used. Giving an easy step to maximize the use of the iPod battery.

UPDATE: We’ve tried to understand the new Apple MacBook Pro battery life ratings compared to older models. It is difficult to quantify generational differences because Apple is being tested with a benchmark battery more difficult, while improving the efficiency of new machines via Penryn chips and LED backlighting. Is it a wash, then? Not really. We have just received the comparative figures from previous generations of computers and current Apple. They read as follows: MacBook and MacBook Pro have life 30-45 minutes longer than the previous generation using the same Wireless Web test. With LED backlighting, the numbers jump to one hour.

Note that the laptop LCD screen is not standard 17-inch LED-backlit, so it is not expressed in these forecasts. Finally, Apple is the most difficult test before being, as we saw in the air, the battery or put me in these machines will probably be even less. (The battery claims of previous generations were much higher because the old test was basically typing in a text editor with Wi-Fi off, which obviously inflated previous estimate of battery life beyond reason.)

Previously (and damped)

I just talked to Apple and find out why the numbers are lower new test, when in reality and real life all these models are higher. It has to do with their testing methodology. Instead of making the laptop battery life as the longest of three tests (a test DVD playback, a test of standard Wi-Fi usage and web browsing, and a trial is the absolute power saving mode does just text editing), Apple just reported half test, which approximates average usage much better than the other two. Previously, they had a number for the unlikely scenario that you want to be editing a text document while not connected to the Internet. If you ran the same tests on the three models, the newer laptops that actually rate higher than before, says Apple. Jason Chen -

Before this (and repaid):

The battery life of the new MacBook and MacBook Pro 17″ battery has dropped dramatically in the new revision. After having been the interpreter of the battery of 5.75 hours, the 2.6GHz MacBook Pro 17″ dropped to 4.5 hours. There are several explanations, but none of them can explain the change because the numbers do not add up:

The first is Apple’s new life “wireless productivity battery. According to Apple, this measure of autonomy in the use of Wi-Fi standard Web browser pages, in collaboration with the mail and other Internet-related applications. It seems that if Apple is now much more cautious and rigorous in their testing of MacBook Pro 13 Battery performance. But what can explain the decrease does not seem as simple as that.

The MacBook Pro 15 battery life , for example, remains unchanged throughout the CPU speed even with the control method of the new battery. Apple sources indicate that the use of LED screen backlighting saves about 30 minutes of battery life. But is that enough to offset the decline against the battery life of the MacBook Pro 17 “

The last article we know the 5 tricks to keep your device battery last longer. The following content is to list the rest 4 tricks.

If you’re a recent convert to smartphones, you’re probably still discovering all the amazing things that your new BlackBerry, android phone or iPhone can do. But one thing you most likely found out right away: the more you do, the shorter your laptop battery lasts

Turn Off Everything

The simplest way to cut power to a minimum is to put your smartphone into “airplane mode.” You turn your BlackBerry or iPhone into a music player and personal organizer, and you won’t be able to receive e-mail messages or make or receive phone calls, but you will stretch your Dell Latitude D420 Battery .

“In airplane mode and running just the alarm clock, your iPhone battery will last up to a week,” said Kyle Wiens, co-founder of ifixit.com, an online iPhone and Mac laptop repair company.

Disable the animations

The hotter your laptop feels, the more Dell Latitude D410 Battery power it is using. and one of the biggest users of power is Flash animation, the technology behind many online videos and animated ads. To improve battery life, disable Flash when not using wall power. BashFlash and ClicktoFlash for Macs and Flashblock for PC are programs that will automatically restrict Flash.

Get an app to aid You

There are a number of applications that can help monitor Dell Latitude D820 Battery life and shut off various functions that cut down on a mobile device’s effective power.

Battery Go and myBatteryLife tell iPhone owners how much charge they have left and how that power translates into minutes of talk time, music, video and Web surfing.

NB BattStat alerts BlackBerry owners to the amount of battery charge remaining, as well as the Dell Inspiron 6400 Battery ’s temperature. (Hot batteries lose power more quickly.) The device can be set to vibrate or sound when a predetermined low battery level is reached.

Radio Saver will monitor your BlackBerry’s mobile coverage and shut off the device’s mobile circuitry when you are out of range of a cellular signal.

Best Latitude D400 Battery Saver allows owners of mobile phones using the Symbian operating system (including models from Nokia and Sony Ericsson) to create battery-saving profiles. For example, certain features can be automatically turned on when the phone is connected to a wall plug, or Bluetooth can be automatically disconnected when the battery charge drops below a certain level.

For laptops, programs like Battery Health Monitor (Mac) and Laptop Battery Power Monitor (PC) keep track of battery charge and estimate how many more times you’ll be able to recharge your battery.

Realize the End Will Come

The older generation of nickel cadmium XPS M1210 Battery suffered from memory issues; if you didn’t fully charge and discharge one, it would hold a progressively smaller amount of juice.

Today’s lithium-ion Dell XPS M1530 Battery don’t suffer from memory loss, so it is safe to top off a battery.Lithium-ion batteries cannot be overcharged; a device’s circuitry cuts off the power when they are full. However, manufacturers still recommend that a laptop not be continually connected to power once the battery is at its capacity. If a laptop won’t be used for several months, it should be stored with the battery in a 50 percent charge state.

all batteries can be fully charged and discharged for a fixed number of cycles; lithium ion Dell XPS M1330 Battery typically last between 300 and 500 cycles. Information on the number of cycles can be obtained at manufacturers’ Web sites, or at batteryuniversity.com. No matter how well you husband your battery’s resources, there comes a time when you’ll need to send your battery to its final resting place.

Like most things nearing the end of their life, your battery will stay awake less and sleep more. “If your battery lasts only an hour after you’ve charged it,” said anthony Magnabosco, owner of Milliamp.com, a battery replacement company, “you know its time is up.”

Apple has determined that certain lithium-ion batteries containing Sony’s production pose a security risk, it may lead to economic overheating, the rare cells.

Of the affected batteries were sold worldwide in October 2003 with the following notebook computer use: By August 2006 PowerBook G4 12 inch Battery , PowerBook G4 12 inch Battery and PowerBook G4 15 inch (aluminum) Battery .

Apple has initiated recall of the affected laptop batteries and has initiated a worldwide exchange program to provide a new replacement battery free of charge to eligible clients. This process is ongoing with the U.S. Consumer Product Safety Commission co-operation (CPSC) and other international security agencies.

Make sure your battery

Please use the following table to determine the PowerBook G4 Battery model and serial number for your iBook or PowerBook. If the first five well-known within the battery’s 12-bit serial numbers have dropped, please order the immediate replacement of the battery.

To view the model and serial number label at the bottom of the PowerBook G4 17 inch Battery, you must remove the battery from the computer. The serial number is printed in black or dark gray, under a bar code fonts. See below photos.

Note: When you remove from the iBook or PowerBook G4 Battery recall, consumers should plug in the AC power adapter until a replacement battery arrives on the computer.

If you have participated in these computer models or recently purchased an Apple iBook G3 received an extra battery or A1008 A1012 battery recall, please check your battery serial number, if you receive a replacement battery is the impact of this program.

National and regional distributors, cataloging, and Apple’s online and retail stores sold from August 2006 to October 2003 with the battery computer. These batteries were also sold separately, may have been replaced by service units.

Exchange process

To begin the process of replacing the battery, you will be asked for your iBook G4 battery and PowerBook G4 notebook computers, your battery serial number, serial number and mailing address.

In Australia, New Zealand, the South Pacific islands and Asian clients (excluding Japan) should contact your local Apple Authorized Service Provider to obtain a replacement A1057 A1060 battery.

After serial number verification, a new battery will be shipped to you free of charge. When you receive the replacement A1078 Apple A1079 battery, please use the same packaging, packaging and shipping label, including the proper handling of pre-paid back to the battery recall apple.

Note: If your battery serial number does not meet the scope listed above, you do not have to exchange the battery.

The detail content from Apple.com Laptops-battery.co.uk hopes that help you.

As Apple Inc. prepares to unveil its own sequel Wednesday, the biggest question is whether changes since the early 1990s in the technology landscape¡ªand consumer habits¡ªcould give this tablet story a happier ending for vgp bps2b battery. Early tablet forays lacked high-speed wireless networking and Internet-based content, which Apple can tap for its device.

There are still plenty of obstacles, veteran tech watchers say, including questions about cost and battery life as well as competition from laptops and smaller devices such as Apple’s own iPods and Amazon of Fujitsu t4010 battery .com Inc.’s Kindle reader.But few people underestimate the ability of Apple Chief Executive Steve Jobs to turn out a product that will get people talking, and at least some of them buying.

“I would expect to see something that is very exciting, but like the first iPhone, not for everybody,” said Mitchell Kapor, an investor and PC industry pioneer who designed the hit spreadsheet Lotus 1-2-3.People familiar with the company’s plans say Apple will unveil Wednesday a device that has a 10-inch touch screen for Fujitsu t4020 battery ,Fujitsu t5010 battery which can be manipulated by multiple gestures akin to those popularized by the iPhone.

The larger display provide more space for software of the sort now found on the iPhone¡ªincluding games, navigation and social networking services¡ªwhile allowing users to access traditional media like books, newspapers, movies and TV in new ways of vgp bps2b battery, these people say.Based on component costs, analysts say Apple’s tablet could be priced as high as $1,000¡ªthough some estimates put it as low as $600, between its most expensive iPod touch and the cheapest MacBook computer.

The underlying concepts behind such products can be traced to the Dynabook, a design for a portable device proposed in the late 1960s by computer scientist Alan Kay. Companies started working on comparable products by the late 1980s, hoping to substitute pen-type devices for keyboards to input data for lifebook t4010 battery ,lifebook t5010 battery.But many high-profile start-ups were hurt by defects in underlying technologies, particularly in handwriting recognition and displays. Momenta Corp., for example, launched a six-pound, pen-based computer in 1991 that cost $5,000; the company folded less than a year later.

When Apple first tried to crack the market in the 1990s with a small device called Newton; its handwriting recognition was bad enough to prompt parodies in the “Doonesbury” comic strip for PA3399U-2BRS battery . A few years after Mr. Jobs returned to Apple in 1996, he shut the product down.Microsoft Corp., meanwhile, turned out versions of Windows that could be manipulated with a pen and were used in tablet-style products. But few have found many users beyond businesses with workers that need to be standing, like insurance adjusters and some sales representatives.

Industry executives say the market has changed dramatically, as have technology companies’ goals. In the early 1990s, companies were trying to turn existing laptops into pen-based productivity tools on ThinkPad T60p Battery, says Jerry Kaplan, Go’s former chairman and co-founder. Apple, by contrast, is really making a larger version of its iPhone¡ªa device that is already a consumer hit.

Hardware technology has advanced dramatically in the past decade, making it easier to offer devices that are smaller, more powerful and less expensive of lifebook t4020 battery . Modern touch-screens are more responsive and don’t require electronic pens.The broad acceptance over the past decade of Wi-Fi networking in homes and public places and the rollout of 3G cellular networks in the past two years has made it possible for consumers to get accustomed to using their laptops and cellphones for viewing music, movies and other entertainment.

“I believe the time has come,” says Kamran Elahian, the entreprenuer and venture capitalist who founded Momenta, of Apple’s expected tablet.But Apple is entering a market that is more complex and crowded of A1008 battery . The rivals include lightweight netbook computers that can sell for less than $300 as well as specialized devices like Amazon’s Kindle.

Other computer makers are pushing competing efforts on PA3399U-2BRS. Lenovo Group Ltd., for example, recently unveiled its IdeaPad UI, a hybrid notebook with a detachable screen that works as a stand-alone tablet.A keyboardless computer that is too big to fit in your pocket? Silicon Valley has seen that movie before, and it flopped each time.

The official score sheet had the Blues for 33 hits Monday night against Columbus. They might have been the 33 quietest hits of the season for ThinkPad T60 Battery.After re-establishing ferocious forechecking and a physical edge recently, the Blues put forth minimal intensity against the Blue Jackets and saw their four-game winning streak come to an end with a 4-2 loss.

“I didn’t think we had much jump tonight, even when we called upon it,” Blues coach Davis Payne said. “It didn’t seem like we were able to get our gear shifted for the third period … for whatever reason. Very little net traffic, very little secondary possessions for Fujitsu lifebook t4210 battery. I thought we lost a majority of puck situations when we could have been much stronger. We’ve got to regroup.”

After running their road record to 11-3-3, the Blues are 1-3-1 in their last five away games. They will continue their three-game trip with back-to-back games Wednesday in Montreal and Thursday in Ottawa for VGP-BPS8 , vgp bps8a fortunate on a couple of its other goals Monday, the Blues were a disjointed group in the defensive zone.

The Blues entered Monday’s game having not allowed a goal in the third period of their last three games. But just 1 minute, 24 seconds into the final period, the Blue Jackets’ Chris Clark gave his team its two-goal cushion.Clark’s fifth goal of the season came after a flurry in front of the Blues’ net of Fujitsu lifebook t4210 battery. After the Blues opened a 1-0 lead on Paul Kariya’s ninth goal this season, a power-play goal just 1:11 into the game, the Blues mustered few scoring chances.The ones they did, Columbus goalie Mathieu Garon snuffed out.

“It felt like a step backwards,” said Blues goalie Chris Mason, who made his seventh straight start. “That’s definitely not the style of hockey we were playing for Fujitsu lifebook t4220 battery. I don’t know if we got a little ahead of ourselves after winning four games. But we definitely didn’t bring the work ethic that’s helped us win those four games.”

The Blue Jackets won the faceoff battle 67 percent to 33 percent Monday and also had nine takeaways.”We weren’t executing a lot of our passes out of our zone for VGP-BPS8 ,vgp bps8a ” Blues defensman Barret Jackman said. “It didn’t give us a chance to get our legs going. A lot of turnovers keeps you stopping and starting, back and forth.”

Garon made the start despite suffering a wrist injury during Monday’s morning skate. He rushed off the ice holding his wrist after being hit by a shot in practice, but then shook it off in time to play for A1175 battery .”Five minutes after I got off the ice, I knew I was going to play,” Garon said after making 22 of 24 saves against the Blues. “I could feel it a couple of times (during the game), but it didn’t bother me.”

Only a few minutes after Kariya’s goal, the Blue Jackets gave Garon some offensive support.Columbus’ Raffi Torres took a stretch pass from teammate Kris Russell and scored the first of his two goals in the game for Fujitsu lifebook t4220 battery. Torres sent a wrist shot on net, and it deflected off the stick of Mike Weaver before sneaking past Mason.Weaver was victimized on the Blues Jackets’ first two goals Monday.

A shot by Derick Brassard later in the period deflected off Weaver’s left skate and bounced straight to Torres on Mason’s doorstep. He buried the easy look for a 2-1 lead in the first period for A1175 battery .”(Brassard) was actually trying to shoot that puck and I was in the right position to block it,” Weaver said. “It just went off my skate and right to (Torres). Bad luck, but you’ve got to work harder for your luck.”

Torres’ 15th and 16th goals of the season marked the first time the Blues had trailed in a game since their 4-2 loss to Anaheim on Jan. 7.
Keith Tkachuk tied the score 2-2 just 3:44 into the second period, and fortunately for Tkachuk, goal No. 11 this season didn’t go into the net like his last goal — off his mouth for pavilion dv2000 battery .This time, after a power move to the net, Tkachuk backhanded a shot that went in off the glove of Russell. Erik Johnson notched an assist on the goal, which was his first point in his last seven games.

The 2-2 score didn’t last long. Thirty-six seconds after Tkachuk’s goal, Rick Nash scored a power-play goal, his 22nd goal of the season, for a 3-2 advantage. After falling behind 4-2 in the third, the Blues hurt themselves with back-to-back penalties by Jackman and David Backes for ThinkPad T60 Battery. “We’ll take a step back, and we’ll look at it and address certain areas,” Payne said. “Some of them were puck decisions, some of them were battle-level areas. We’ll simply address those areas tomorrow.”

Even for those Mac users that don’t have an iPhone (like myself) this is a good thing, as it seriously contributes to Apple’s bottom line, which means more money in the coffers for Macintosh R&D as well iTunes/iPhone/iPod and Apple PowerBook G4 Battery.

Unfortunately, with wild popularity comes increased scrutiny. As a result, when something goes wrong with the iPhone, there is often a large backlash.

Just this sort of thing has happened with the recent release of iPhone OS 3.1. It seems that many users are experiencing rapid discharging of the A1060 battery since updating.

In perusing Apple’s support forums, there are a number of threads, like this one, detailing the woes of those who have installed iPhone OS 3.1 on their iPhones only to experience rapid discharging of the battery. Even after turning off some of the noted Apple A1045 battery-draining processes, such as wi-fi, bluetooth, and push notifications, people have been experiencing a reduction in battery life.

In some cases, it seems attached to a corrupt file or application in the iPhone. In these instances, restoring the iPhone and creating a new profile (rather than importing old information) seemed to resolve the issue. Unfortunately for many others Apple A1061, even after performing this procedure, the problem still remains.

Apparently, though, Apple has responded to the issue and has distributed a small battery tracking application, along with a short list of troubleshooting questions, to many posters on the above-mentioned thread.

Judging by the wide range of this problem and Apple’s response, is is very likely that we will soon see another update to iPhone OS that will resolve this issue cause by Apple A1079. Until that time, though, iPhone users are left to deal with the problem themselves.

Fortunately, OWC is here to help. While we can’t fix the underlying problem —that’s Apple’s domain— we’ve at least got a temporary solution for your power problems: extended battery packs.

The most form-fitting option is the Energizer Energi To Go AP iPhone Charger, which integrates a protective sleeve with either a 1000 mAh or 1500 mAh battery for extra time between Apple A1078  chargings.

For a less specific option, there are the Macally JBox mini and the Cellboost iRecharge. Both these items allow you to simply attach to your iPhone via its USB cable and charge it that way with VGP-BPS9. While not nearly as slick an option as the Energi To Go, these items have the added benefit that they can be used with any device that can be charged via USB.

I have had the iPhone 3G for 6 days now and we have developed an intense love/hate relationship. It is exactly what I want in a phone when it comes to multimedia browsing but there have been some serious drawbacks for my Apple A1079 Apple A1175.

When I first got the phone and setup iTunes, I went absolutely crazy with the free apps. This was probably a bad idea because the phone has been crashing quite a bit. I have about 175 applications on the phone and because I’m constantly opening and closing applications, I think the phone shuts off like someone who got too drunk too early with my Apple iBook G4 Battery.

The lesson: Try only a few applications at a time and be strict about what applications you keep on your device and which ones you leave on your computer such as Apple PowerBook G4 Battery.

Now if you are going to download a free app for your iPhone, I seriously recommend downloading iPint by Carling. It lets you drink a virtual beer! No calories, no mess but no drunk. Everything is a compromise except Presario R3000 Battery.

The battery life on the iPhone 3G is a tough call. It totally depends on how much you use the battery intensive programs like the GPS of  Dell Inspiron E1705 Battery. Personally, I use absolutely everything on the phone with a total disregard for what will drain my battery. This means that I get about 18 hours of total time before the phone shuts off. That isn’t so bad considering I charge my phone daily. In fact, I kind of like the fact that the phone has enough features to drain the battery that quickly.

Although waiting in line was a really grueling experience, I’m still very happy with my iPhone purchase and will continue to trick Sony VGP-BPS3 out.

To get an idea of just how grueling the experience was, the guys over at EETimes brought a video camera to the scene and you can check out the video in which they interviewed me after being awake for 26 hours than my Sony VGP-BPS4. Make sure to watch until the end of the video where they absolutely FREAK out with their new iPhone 3G and make a dash back to their HQ.

Expected, Microsoft’s Zune music player, portable media players in the field of the first application of Wi-Fi capabilities for aspire 3000 battery, portable media player markets, including portable digital audio players. End of this year is expected to portable media player sales will reach 190 million units last year, sales of portable media players and 1.7 million units. In-Stat noted that Microsoft’s portable media player market share will not occupy too much, the market is occupied mainly by Apple is expected to Microsoft, in its media player with Wi-Fi capabilities of the initiative will encourage other portable media players manufacturers in its products to configure Wi-Fi capabilities. For example, Apple a1175 plans to launch later this year to support Wi-Fi enabled iPod. However, In-Stat estimates that in 2007, more than 5% of the portable media players will have Wi-Fi capabilities.

In-Stat, said the Wi-Fi and Bluetooth integrated into a single chip may also be of great help to promote Wi-Fi in mobile phone applications. The analyst firm noted that the chip maker Marvell, Broadcom and Texas Instruments have announced a single-chip Wi-F / Bluetooth chipset, while the Texas Instruments and NXP two Bluetooth mobile phone chip market leaders have introduced a single-chip Wi-Fi and inspiron e1405 battery and single-chip Bluetooth device package. In-Stat says shipments of dual-mode Wi-Fi/cellular phones are expected in 2007 will reach 27 million, six million last year, integrated Bluetooth and Wi-Fi chipsets will help to promote Wi-Fi in the mobile phone applications.

Although based on the draft 802.11n standard Wi-Fi home wireless access equipment only in 2006 as a whole Wi-Fi routers for VGP-BPS8, gateways and home access device shipments in a little more than 2 percent, but, In-Stat expects This year, the percentage will increase to 15%. The analyst firm believes that this was mainly due to less than 100 dollars this year, the draft 802.11n wireless router will be more widely used, and chipset manufacturers to launch a small volume of 802.11n chipsets, will further promote its application. However, other analysts are being asked consumers not to use the draft 802.11n products, in order to avoid wireless standards as early as 2008, need to finalize the hardware vgp-bps2 upgrade.

While I was benchmarking third-party RAM with a MacBook Pro battery  this week, I noticed that the computer was taking a huge hit in performance when it wasn’t running on Apple-supplied memory. A minor decrease in performance might be unlikely, but a 37 percent plunge in processing power seemed impossible. After some backtracking, I realized that I had been running the benchmarks without the battery installed after I’d swapped out the stock RAM for third-party memory. The MacBook Pro Discount laptop battery was running off AC power for both tests, but the battery was installed only while I was running the benchmark with 4 Gbytes of stock RAM.

After some digging, I found that the performance drop is documented on Apple’s support Web site–though honestly, Apple’s reason for forcing a drop in processor speed doesn’t make a whole lot of sense. Apple justifies the speed reduction by explaining that it “prevents the computer from shutting down if it demands more power than the A/C adapter alone can provide.” But what happens when a battery is no longer able to hold a charge? Does the processor speed drop in that case as well?

We benchmarked our 2.53-GHz MacBook Pro with 4GB of RAM using Cinebench R10’s multiprocessor test, and achieved a score of 5,549 with the battery present and 3,504 with the battery removed.

Lesson learned: The battery stays in. If you’re a MacBook or MacBook Pro owner, you’ll get the best performance out of your system when you leave the battery in. A small extension of your Dell laptop battery’s life span is not worth a 37 percent drop in performance.

If you’re operating a MacBook or MacBook Pro system with a dead battery, I invite you to benchmark your own system: Try testing your notebook with and without the dead Pavilion DV8000 battery installed. You can use a free download of Cinebench R10 to benchmark your Apple system. Be sure to close all applications and disable Airport and Bluetooth before you run the test. And please let us know your results as a comment below.
