Toshiba Satellite C855-S5206 Review

Toshiba Satellite C855-S5206

The Toshiba Satellite C855-S5206 is yet another configuration from the laptop maker’s C855 cheap full-size 15.6″ series.

Sporting the 2nd Generation Intel Core i3-2370M “Sandy Bridge” dual-core processor, 4GB of RAM, and a 500GB hard drive, the Satellite C855-S5206 is a mid-range system with the last year’s CPU and the latest design. The CPU’s performance is on the middle of the road between the Intel Pentium B-series, such as B950 and B960, and the 2nd Gen i5 family, meaning that the laptop is good for everyday productivity and media consumption.

Delving further inside, the C855-S5206 packs a DVD burner, USB 3.0 technology, HDMI, stereo speakers, and a 6-cell lithium-ion Toshiba pa3534u-1bas battery with unknown battery life. The display is the classical 1366×768 15.6-incher and it’s powered by the Intel HD 3000 graphics processor, located on the i3 chip.

The C855 has an unassertive and practical look with plastic surfaces and a chiclet keyboard. This series comes in various colors. This model is completely black or “Satin Black”, officially.

Overall, the Toshiba Satellite C855-S5206 is an average laptop for day-to-day operations. It brings no surprises, but also no disappointments. What’s really important for its target market is the price and in this segment the machine is a superb one, with a price tag of $400.

Review Dell Precision M4600: Mobile Workstation Muscle

Review Summary:

The Dell Precision M4600 is one of the most powerful 15-inch mobile workstations available. Just be ready for high costs if you customize it.


  • Great 1080p IPS display option
  • Plenty of ports
  • Extreme performance


  • Poor laptop battery life
  • Thick and heavy
  • Weak backlit keyboard
  • Expensive if heavily customized

Dell Precision M4600 Full Review: Mobile Workstation Muscle

A “mobile workstation” isn’t the same as a typical business notebook and the 15-inch Dell Precision M4600 isn’t the same as a typical mobile workstation. This impressively durable powerhouse is available with just about every high-end component you can imagine … but is it worth spending more than $4,000 on a mobile workstation? Keep reading to find out.

Build and Design

The Precision M4600 certainly looks like the old, boxy Dell business notebooks from the previous decade, but there’s something to be said for the idea that form follows function. The thick chassis is made of a combination of aluminum and magnesium alloy in order to give this mobile workstation some added durability.

only AU $63.77

Granted, most of the graphic artists and engineers using mobile workstations are keeping them at a desk, but if you need to travel with your PC then all that thick metal will keep those high-priced components safe.

The screen lid is pretty rigid and provides enough protection to prevent the screen from distorting when you press on the back of the display. We wouldn’t recommend standing on the lid, but it should survive an accidental drop without any trouble. The screen hinges are very strong with enough tension to require two hands to open the lid. The remainder of the notebook is similarly tough with no obvious signs of chassis flex under pressure and no “squeaks or creaks” when you try to twist the notebook in your hands. In short, this is a very solid mobile workstation.

The bottom of the M4600 is pretty well sealed at first glance. You’ll have to remove the Dell Inspiron 1520 Laptop Battery from the bottom of the notebook to reveal the three screws that have to be removed in order to access the various internal components. The M4600 uses two large cooling fans to help keep the system cool but there are actually four air intakes to make sure there’s plenty of air flow for high-power processors and graphics.

Ports and Features

A mobile workstation is very much focused on business and it’s pretty common for people to need to connect a mobile workstation to a wide variety of external storage devices and displays. To that end, Dell provides five USB ports (two USB 2.0, two USB 3.0 and an eSATA/USB 2.0 combo port), FireWire, and even an ExpressCard slot for expanding your port options. In addition, you get three video out ports (VGA, HDMI and DisplayPort). Sure, the M4600 is pretty thick, but you get a great deal of connectivity in return.

WiFi Napping – An Adorable Way To Double Mobile Phone Battery Life

A Duke University student named Justin Manweiler has created a way to extend the battery life of mobile devices by making changes to WiFi technology. He calls it “SleepWell.”

The more wireless devices there are in a space, the higher the drain is on each one’s mobile phone battery as they access the internet. Downloading a movie in a city uses more battery power than downloading a movie in a rural area over a public WiFi network.

Manweiler’s system embraces this — when your WiFi-enabled device is in standby and it detects other WiFi devices that are actively using the network, it puts its connection to sleep. This saves battery life both for your own device and for the one using the connection.

Nokia unveils Symbian Belle-powered smart phones

Nokia has showcased an update for its Symbian platform, along with three soon-to-land handsets running the operating system.

Dubbed Symbian Belle, the revamped OS boosts the number of homescreens available on a phone from three to six to allow users more space to store apps, as well as providing more scope to customise their layouts with new, different sized live widgets.

Nokia has also added an Android-style pull down menu and taskbar to access notifications from any of the home screens. And perhaps most excitingly, it has brought Near Field Communications (NFC) tech to the phones for the first time to enable Nokia phone owners to use their handsets to pay for low ticket items by swiping them over a reader.

Contacts, videos and images can also now be shared with other NFC-enabled devices too and there’s the option to unlock new content in games by touching two Symbian Belle devices together.

Heading Nokia’s Symbian Belle charge are three handsets, dubbed the 600, 700 and 701.

Billed as Nokia’s smallest-ever smartphone with dimensions of 110 x 50.7 x 9.7mm, the 700 teams a 1GHz processor with a 3.2 inch AMOLED screen ClearBlack display, expandable memory of up to 32GB via microSD card support and a five-megapixel camera.

Toshiba pa3399u-2bas battery – Brand New 4400mAh Only AU $61.68

Toshiba pa3331u-1bas battery – Brand New 4400mAh Only AU $59.71

Despite the similarity of their titles, the 701 is a real step up. Features include an eight-megapixel camera, secondary snapper for video calls and a 3.5-inch touchscreen that Nokia claims is the “brightest-ever mobile phone display”.

And completing the triumvirate is the 600. Designed for music fans, this is Nokia’s loudest phone so far and offers the option to stream music wirelessly to NFC-enabled accessories. It’s also home to a five-megapixel camera and a 1GHz processor and will be available at a lower price point to the 700 and 701.

Battery extenders for HTC, Samsung, Blackberry smart phones

Battery cases are no longer the exclusive domain of iPhones, as Android-based phones ramp up in popularity.

One of the most annoying aspects of travelling is running out of battery on your smartphone just when you really need it — when checking emails just after getting off a long flight, or trying to access maps in a foreign city.

iPhone users have had a good range of options to bump up their battery life, but there haven’t been any for people getting inadequate battery life from handsets like the HTC Desire HD, Samsung Galaxy S2, Google Nexus S or BlackBerry.

A new range of smartphone battery skins from XPAL is now addressing that gap in the marketplace.

XPAL says it is tackling the challenge of making battery cases for a broader range of handsets head-on, even though Android/BlackBerry/Windows Phone 7 handsets often have a shelf life of less than six months.

Acer as07b72 battery – Brand New 5200mAh Only AU $70.29

Acer travelmate 4230 series battery – Brand New 4400mAh Only AU $68.16

Currently, XPAL has cases available for:

  • HTC HD7
  • HTC HD2
  • Samsung Galaxy i9000 / i9003
  • HTC Desire HD
  • Samsung i9020T
  • Google Nexus S
  • BlackBerry 8520
  • BlackBerry 8530
  • BlackBerry 9700
  • BlackBerry 9780
  • HTC Sensation
  • Samsung Galaxy S2 (available end of August)

Above: a PowerSkin on an HTC Desire HD.

The PowerSkins all have a capacity of between 1200mAh and 1620mAh, depending on the phone model, which means that they deliver roughly the battery life of the handset’s inbuilt battery again.

Because charging the handset’s inbuilt battery too often can wear it out prematurely, PowerSkins also come with an on/off switch so you can decide when to start giving your handset additional juice — the best strategy is usually to only do so when the handset’s inbuilt laptop battery is about to run out.

Full review MSI GT60 gaming laptop

Call it the attack of the awesome ivy. MSI’s GT60 gaming notebook is one of the first notebooks to hit the market with Intel’s third-generation Ivy Bridge processor. Combine that with a vibrant 1080p display, good audio quality and a powerful Nvidia GPU and you’ve got a recipe for hours of questing, grinding and saving the day at a rather affordable price.


MSI GT60Click to EnlargeThe GT60 isn’t as pretty as say, the Alienware M17x, but it’s still a handsome piece of machinery. While we loved the lid’s center panel of black brushed aluminum with a backlit MSI logo, we’re not fans of the wide strips of plastic lining the sides and bottom. However, the side panels’ distinct slope created some interesting angles throughout the design we couldn’t help but admire.

The notebook’s interior mimics the lid, featuring plastic side panels with a brushed black aluminum palm rest. However, our eyes were consistently drawn to the top of the keyboard deck and the glossy black plastic function key bar. Reminiscent of a Transformer headpiece, the angular bar ensconces a pair of speakers and the large chrome power button in the middle. It also holds touch controls for Wi-Fi, touchpad and Turbo.

We don’t foresee many people moving the 7.8-pound MSI GT60 anywhere further than another room in their house. However, the notebook’s 14.9 x 10.2 x 1.8-inch frame can fit into a large backpack or messenger back.


MSI GT60Click to EnlargeThe MSI GT60’s 15.6-inch 1920 x 1080p full HD display delivered mesmerizing color and crisp detail, whether we were reading text, watching video or playing games. At 268 lux, the GT60 outshines the 220 lux desktop replacement category average.

We really appreciate the matte display on this rig, which eliminated the chance of any errant reflections spoiling our view. Viewing angles were nice and wide, maintaining color accuracy from just about every sitting position we tried.

Speaking of reflections, details in the 1080p YouTube trailer of “MIB 3” were so sharp we could clearly make out many of the reflections in the characters’ chrome weaponry. We enjoyed the bleached white sterility of the MIB office. We noticed small instances of fuzziness in a couple of background scenes, but they were few and far between.

During the opening scenes of “Portal 2,” we were enthralled with the ruined sterility of the Aperture Labs as GlaDos came back on line. There was a beautiful juxtaposition of lush green jungle vines woven between the sterile white surfaces of the test rooms and the cold gray steel of the girters and studs holding the lab together. When we finally got our hands on the portal gun and began wielding the titular blue and orange portals, they were nice and bright, offering a much-needed contrast against the stark white backgrounds.


MSI GT60Click to EnlargePowered by Dynaudio Premium speakers, a subwoofer and the THX Studio Pro control panel (pictured), we enjoyed a great sound experience. Although the GT60’s audio defintitely benefits from the THX control panel, we couldn’t tweak as many things as we would have liked. We could only move a slider on settings such as Surround, Crystalizer and Smart Speaker. It would have been nice to adjust settings for Music, Movies and Gaming similar to what HP’s Beats Audio control panel offers.

Still, trumpets on Jay-Z’s “Roc Boyz (And The Winner Is&#x2026;)” were loud and triumphant, meshing easily with the rapper’s braggadocios tenor. However, the bass was lost somewhere in between.

The system redeemed itself as we played through “Portal 2,” where we were rewarded with the delicate clinks of empty bullet casings hitting tiled floors from adorable, but deadly turrets. Fighting enemies in “Batman: Arkham City,” yielded satisfying fwaps, ughs and whooshes. Dive bombing from tall buildings provided a satisfying rush of air and a hearty crunch as we used some unsuspecting bad guy to cushion our landing.


MSI GT60Click to EnlargeSimilar to Alienware notebooks, the MSI GT60 features an island-style keyboard with a full number pad with customizable colored backlighting. We enjoyed configuring our keyboard to our color-coded liking using MSI’s Keyboard LED Manager. While we would have loved the ability to blend colors similar to Alienware’s Command Center utility, we created a pretty bad-ass looking keyboard. The 10 keyboard statuses (including Standard, Idle, Gaming, Normal, Breathing) added a welcome level depth and customization.

The black flat keys were a little on the small side, especially the Backspace and Right Shift keys. Still, we enjoyed ample feedback and achieved 55 words per minute with a 1 percent error rate on the Ten Thumbs Typing Test. That’s slightly higher than our desktop average.


msi gt60 trackpadClick to EnlargeThe glossy polygonal border surrounding the 3 x 1.8 inch brushed aluminum touchpad make it appear smaller than it actually is (pictured). We had no problem sliding our fingers across the stimulating striated surface.

When typing, it’s important to keep your hands curled–one person in our office found that is his hand brushed against it while typing, the pointer moved, causing the cursor to jump. We were also slightly dismayed by the lack of multitouch functionality such as pinch-to-zoom; it’s not crucial for gaming, but would be nice to include. We’re also usually not fans of the single mouse bar, but the GT60’s chrome bar was responsive provided nice, firm feedback.


After 15 minutes of running a Hulu video at fullscreen, the touchpad, space between the G & H keys, and underside of the notebook measured a relatively cool 78, 87 and 81 degrees Fahrenheit. In fact, we were able to use the notebook in our laptop for more than an hour with no discomfort.

Things became slightly warmer after playing “Batman: Arkham Asylum” for 15 minutes. We measured the touchpad at 84 degrees with the space between the G & H keys and the underside measuring 93 and 86 degrees, respectively. These measurements are still below our 95-degree threshold for an uncomfortable notebook.


msi gt60 portsClick to EnlargeA lone USB 2.0 port resides on the notebook’s left side along with jacks for heaphones, a mic, audio in and audio out accompanied by a tray-loading DVD burner. Three USB 3.0 ports and a 7-in-1 card reader can be found on the right. Ports for HDMI, eSATA, VGA and Gigabit Ethernet jack sit along the notebook’s rear(pictured).


webcamClick to EnlargeImages from the MSI GT60’s 720p webcam were fairly sharp under florescent lighting using CyberLink YouCam. We could see the stitching in our sweater along with the logo. There was a small amount of oversaturation, but our skin tone and gray sweater looked pretty accurate (pictured).


Talk about super-powered. The MSI GT60 features a third-generation (Ivy Bridge) 2.3-GHz Intel Core i7-3610QM processor with 12GB of RAM, dual 500GB 7,200-rpm hard drives and an Nvidia GeForce GTX 670M GPU with 3GB of VRAM. We had an absolute blast cleaning up the mean streets of Gotham in “Batman: Arkham City.” As we played, we had 10 open tabs in both Google Chrome and Internet Explorer while running a full virus scan. The Dark Knight went about his crime-fighting duties without any noticeable latency.

The GT60 delivered impressive scores on our synthetic tests. The rig notched 3,336 in PCMark 07, a bit above the 3,163 desktop replacement category average. The ASUS G75VW-DS71 and its third-generation 2.3-GHz Core i7-3610QM quad-core processor scored a lower 3,041.

Booting the 64-bit version of Windows 7 Premium only took the GT60 53 seconds, thanks to the dual 500GB 7,200-rpm hard drives. That’s enough to beat the 0:60 category average and the G75VW-DS71’s time of 0:66.

The GT60’s dual drives duplicated 4.97GB of mixed media files in 1 minute and 8 seconds, a blazing fast transfer rate of 74.8 MBps, far above the 37.4 MBps category average. The G75VW-DS71 (30 MBps) was left in the dust.

During the OpenOffice Test, the GT60 matched 20,000 names to their corresponding addresses in 4 minutes and 26 seconds. That’s slightly below the 4:24 desktop replacement average.

Graphics and Gaming

Playing games on the MSI GT60 is an absolute joy. We couldn’t keep the smile off our faces during “Batman: Arkham City” as we cleared out a room of 10 or more thugs. We made easy work of them with fluid roundhouse kicks, batarangs and backhands, with our ebony cape billowing menacingly all the while. The views of the dilapidated prison were grim, yet breathtaking complete with neon signs glowing weakly against the unshakable gloom of the night sky.

The GT60 delivered synthetic benchmarks that were almost as awesome as battling the undead juggernaut Solomon Grundy. The notebook’s Nvidia GeForce GTX 670M GPU with 3GB of VRAM delivered an epic 19,359 on the 3DMark06 benchmark. That’s 6,408 points above the 12,951 desktop replacement average. The ASUS G75VW-DS71 and its GeForce GTX 660M GPUs with 2GB of GDDR5 VRAM scored a respectable 16,028.

When we ran the “World of Warcraft” benchmark, the GT60 notched a face-melting frame rate of 190 fps on Good at 1920 x 1080p. That was more than enough to best the G75VW’s score of 158 fps and the category average of 142 fps. When we cranked the test up to maximum, the GT60’s score dropped to 106 fps.

We also ran a few benchmarks with the graphically taxing “Batman: Arkham City.” With DX11 on, 4X MSAA, Graphics Very High and the resolution at 1366 x 768 pixels, the MSI GT60 scored an impressive 47 fps while the G75VW notched 31fps on the same settings. When we switched to 1920 x 1080p, the GT60’s frame rate dropped to 28 fps, slightly below playable.

Traversing the sprawling campus of Aperture Labs was challenging, but it was never an ugly experience on the GT60. Shooting the portal gun was nice and slick. Our favorite part was hurtling towards the ground before placing a portal that would catapult us to another part of the test. The illusion of speed was both exhilarating and dizzying.


msi gt60 battery calibrationClick to EnlargeMSI doesn’t bog the GT60 down with needless software, installing a skeleton crew of utilities and software. There’s MSI SuperCharger that automatically detects and charges attached mobile devices. We also liked S-Bar, a panel of shortcuts for programs, Windows accessories, and function keys.

Additional MSI-branded programs include MSI VGA Overclock, Battery Calibration (pictured) and BurnRecovery.

Fellow gamers will appreciate the addition of Qualcomm Atheros Killer Network Manager. The software identifies important activities such as gaming, video and audio network data, ensuring that the receive priority for high-speed connectivity.

Other third-party software includes Windows Live, Microsoft Office Starter, Google Chrome, Adobe Reader X, Norton Online Backup and a 30-day free trial of Trend Micro Titanium Internet Security 2012.

The MSI GT60 comes with a 2-year Limited Warranty.


Our $1,559 review unit of the GT60 features a 2.3-GHz Intel Core i7-3610QM processor with 12GB of RAM, dual 500GB 7,200-rpm hard drives and an Nvidia GeForce GTX 670M GPU with 3GB of VRAM.

The $1,399 base model (GT683-841US) offers a 2.2-GHz Intel Core i7-2670QM CPU, 12GB of RAM, a 750GB 7,200-rpm hard drive and Nvidia GeForce GTX 560M with 1.5GB of RAM. There’s also the $1,499 GT683DX-840US, which comes equipped with a faster Nvidia GeForce GTX 570M GPU with 1.5GB of RAM.

Battery Life

During the Dell inspiron 1545 battery Test (continuous Web surfing over Wi-Fi), the GT60 lasted 4 hours and 37 minutes. That’s 1 hour and 2 minutes longer than the 3:35 desktop replacement category average. The ASUS G75VW-DS71 only lasted 3:11.


MSI GT60Click to EnlargeMSI managed to pack a ton of power into a relatively portable and affordable platform. For $1,599, gamers walk away with a notebook that’s equipped with Intel’s quad-core Ivy Bridge processor, a seriously powerful Nvidia GPU and a design that can keep its cool during a heavy gaming session. Gamers should also consider the Alienware M14x. Although it has a smaller 14-inch screen, the $1,499 M14x offers an Intel Ivy Bridge CPU, 12GB of RAM, a 750GB 7,200-rpm hard drive and a 2GB Nvidia GeForce GT 650M with Optimus. Overall, the MSI GT60 is an excellent choice for hardcore gamers or consumers searching for a notebook that can handle the most demanding tasks.


Top 10 things you need to know about Windows Phone 7.1 Mango

A quick and easy guide to everything that’s good about Microsoft’s Mango update.

Microsoft’s Mango update for Windows Phone, also known as Windows Phone 7.1, has been mooted for months. But the Big M has finally handed over full details of what we can expect from the next-gen version of the ace mobile operating system. Dive in now and read our Top 10 things you need to know about Windows Phone 7.1 Mango.

1 It’ll be available for all current Windows Phones

Perhaps the best news of all. Microsoft isn’t cutting off any older Windows Phones, meaning the likes of the HTC Mozart and Samsung Omnia 7 will be getting the update. This should give it good ammunition to fling at Apple and Google, both of whom have copped flack for not upgrading legacy devices.

2 Bing search has been given an overhaul

This is a seriously impressive update, with visual, audio and voice search. Visual search lets you snap pics of products and barcodes, before delivering local pricing and availability. A new Local Scout feature will track your location and give you results fine tuned to where you are.

3 Twitter and LinkedIn are coming

twitter logo

One of the big misses with Windows Phone 7’s contacts app was the lack of Twitter integration. Happily, this is being added, along with LinkedIn, so you’ll be able to see the latest updates from contacts on these social networks in one place.

4 New partners are on board for 7.1

acer large

Nokia is obviously the big new addition to the Windows Phone family. But Microsoft has confirmed that Acer, ZTE and Fujtisu are also joining the party. That means it should be able to expand hugely in Asia, as well as offer more choice on top of phones from the likes of HTC, LG and Samsung.

5 It won’t be out until autumn


The bad news: Mango is being held back for a few months. That could work in Microsoft’s favour in terms of getting apps ready for it, but may also hamstring it what with the expected September release of iOS 5 and the Q4 release of Android Ice Cream Sandwich.

6 Conversation threads integrate IM, text and Facebook chats

Facebook logo large

Cross platform integration has been one of Windows Phone’s strong points. Mango adds a new conversations feature so you can natter with any given friend no matter what service they’re using. That means if they stop using text and switch to IM, you’ll still be able to see your previous conversation.

7 Multitasking is here at last

This has been known for months, but one of Windows Phone 7’s biggest misses is finally on its way. Multitasking should hopefully mean more devs are willing to bring their apps to WP 7.1.

8 Live Tiles have been bolstered with more live app info

Windows Phone 7 Mango

Arguably the best feature of WP7 was its Live Tiles’ ability to show real time information without having to dive into apps. The National Rail app was a great example. Microsoft says it’s bolstering this, with the chance to get more essential news delivered to the homescreen.

9 Contact group tiles promised

With Mango, you’ll be able to pull together groups of contacts, pin them to the homescreen and then email, SMS or call them at the press of a button. This will help push WP 7.1 is a decent workplace solution, as well as a winning consumer OS.

10 Devs can get working on it straight away

Devs have been told they can get going on updating their current apps and working on new ones straight away. Microsoft has already released the software development kit, so app fanatics can bring new Live Tile layers and improved features to their add-ons from the get go.

Lithium-Ion Batteries Market Set for Boom Courtesy of Hybrid and Electric Vehicles

Driven by plunging prices and accelerating demand from the electric and hybrid automobile market, lithium-ion will emerge as the world’s leading rechargeable battery technology and achieve 350 percent revenue growth from 2010 to 2020, according to a new IHS iSuppli Rechargeable Batteries Special Report from information and analysis provider IHS (NYSE: IHS).

Global lithium-ion battery revenue is expected to expand to $53.7 billion in 2020, up from $11.8 billion in 2010, as presented in the figure below. Revenue will rise to $31.4 billion in 2015, allowing lithium-ion to surpass the current dominant rechargeable battery technology, lead acid.While lithium-ion will find wide usage in mobile electronics products such as cellphones and notebook PCs, usage in cars will fuel the bulk of sales growth.

“Lithium-ion at present is much more expensive than alternative technologies, costing two to three times as much as sodium-sulfur, lead-acid and nickel-metal-hydride rechargeable batteries,” said Satoru Oyama, principal analyst of Japan electronics research for IHS. “However, lithium-ion pricing will decline much more rapidly than the other technologies, coming close to cost parity in 2015, and then becoming the least expensive type of rechargeable battery in 2020. Combined with the inherent advantages of the technology, the increasingly competitive cost of lithium-ion will cause car makers to employ it as their battery technology of choice in future electric and hybrid vehicles.”

Lithium: Just What the Doctor Ordered for Automotive

Lithium-ion delivers several enhancements compared to other rechargeable battery technologies.

These advantages include more flexible form factors and lighter weight. Furthermore, lithium-ion devices have no memory effect, meaning they maintain their full capacity even after a partial recharge. Finally, lithium-ion laptop batteries are considered to be more environmentally safe than other technologies.

These features make lithium-ion particularly attractive for electric vehicles, hybrid electric vehicles and plug-in hybrid electric vehicles.

Because of this, the automotive segment will be the leading market for lithium-ion batteries by 2015, surpassing the current top application, notebook PCs.

Lithium’s Elements of Success in Electric and Hybrid Cars

The dominant battery technology used in hybrid cars now is nickel-metal-hydride. More than 1 million hybrids with nickel-metal-hydride batteries were shipped in 2010, led by the Toyota Prius.

However, shipments of nickel-metal-hydride batteries to the hybrid market will not grow in the future as the use of lithium-ion begins to take off.

One concern regarding the use of first-generation lithium-ion batteries in cars is safety. There can be a risk of fire using existing lithium-ion battery materials due to the high temperatures involved. There have been documented incidents of lithium-ion battery fires in smaller devices, such as PCs and mobile phones.

To achieve acceptable safety levels for hybrid and electric vehicle batteries, lithium-ion battery makers must take steps to prevent internal short circuits which can cause external damage. These steps include improving control of power generation during discharges and enhancing the management of rapid charging.

While automotive will be the dominant market for lithium-ion batteries, notebook PCs and cellphones will remain major markets for the technology, accounting for $12.3 billion in revenue in 2010, up from $7.8 billion in 2010.

Other major uses for lithium-ion batteries include use in solar power systems, smart electricity grids and electric tools.

Is the battery defective? If the computer turns on with the second laptop power adaptor, you know this is not the cause of the problem. Replace the Dell Latitude D500 Series Battery and see if the problem is resolved.

Is it a software-related issue? If a replaced battery does not solve your problem, the next notebook battery troubleshooting tip is to explore the possibility that the software is malfunctioning. If the Dell Inspiron 2200 Laptop Battery status is not being displayed correctly, the software could be causing the problem rather than the TOSHIBA Satellite A200-180  Battery.

Is there a “hiccup” in the system? To power reset the system, or ensure that the motherboard is denied all power, unplug the machine and remove the TOSHIBA PA3284U-1BAS Battery. Hold down the power button for a full minute. Next, reattach the battery and AC adapter and attempt to restart the computer again.

Does the laptop need to be recalibrated? When a new laptop battery is installed, it may fail to charge to a full 100% anymore. If your TOSHIBA PA3356U-1BAS Batterystops charging itself at about 97%, you need this laptop battery troubleshooting tip. Begin the recalibration process by preventing the computer from going to sleep when the battery is low. If your operating system is XP, go to the Control Panel > Performance and Maintenance > Power Options and set the power scheme to “Always On.”

  • Where it says “Alarms,” uncheck the boxes by “Critical battery alarm” and “Low battery alarm.”
  • Where it says “Hibernate,” uncheck the box by “Enable hibernation.”
  • When finished, click “Apply.”

Now the computer can fully drain the battery and when you charge it again, it should reach 100%. It may take two or three times to completely reach 100%.
