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 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

powerskins battery extenders batteries company.com  300x167 Battery extenders for HTC, Samsung, Blackberry smart phonesBattery 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 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

msi laptop battery Full review MSI GT60 gaming laptopCall 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.

Design

MSI%20GT60 g5 Full review MSI GT60 gaming laptopClick 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.

Display

MSI%20KLM Full review MSI GT60 gaming laptopClick 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.

Audio

THX%20Sound%20Pro Full review MSI GT60 gaming laptopClick 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…)” 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.

Keyboard

MSI%20GT60 g1 Full review MSI GT60 gaming laptopClick 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.

Touchpad

MSI%20GT60 g17 Full review MSI GT60 gaming laptopClick 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.

Heat

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.

Ports

MSI%20GT60 g13 Full review MSI GT60 gaming laptopClick 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).

Webcam

webcam Full review MSI GT60 gaming laptopClick 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).

Performance

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.

Software

MSI%20Battery%20Calibration Full review MSI GT60 gaming laptopClick 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.

Configurations

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.

Verdict

MSI%20GT60 g7 Full review MSI GT60 gaming laptopClick 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.

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

batteries1 Lithium Ion Batteries Market Set for Boom Courtesy of Hybrid and Electric VehiclesDriven 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.r banner2 Lithium Ion Batteries Market Set for Boom Courtesy of Hybrid and Electric VehiclesWhile 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.

Battery Breakthrough Could Revolutionize Mobile Computing

Battery Breakthrough Could Revolutionize Mobile Computing batteries company.com  Battery Breakthrough Could Revolutionize Mobile ComputingResearchers at Stanford University have just made a major breakthroughthat may impact the technology industry for years to come: they’ve built a better battery. The project, an attempt to use lithium-sulfur in place of the lithium-ion technology that is used in batteries today, has been in development since 2007. Recently, the scientists’ efforts were rewarded when they created a battery that lasts four times as long as its lithium-ion counterparts while also having the benefit of being “significantly safer” than today’s batteries which occasionally explode after short-circuiting.

Although still a ways off from commercial viability (and availability), the lithium-sulfur batteries promise advances like 80% more capacity, 10 times the power density and, theoretically, the ability to last four times as long as modern batteries.

The new battery technology represents the final step in our quest for always-on connectivity to the mobile web. We already have Wi-Fi hotspots, 3G and 4G networks for Internet everywhere and a host of mobile gadgets from netbooks to iPads and mobile phones to notebook computers. But what we haven’t had yet is a way to keep our gadgets powered up for more than a day or so without a charge. That may be soon about to change.

An Always-On Mobile Web

With these sorts of improvements, lithium-sulfur batteries could lead the way in the next phase of the mobile revolution. They could allow us to fully enjoy the web from anywhere in the world, without having to worry about dying batteries, access to power outlets or having to carry around replacement battery when planning long-lasting mobile computing sessions.

battery%20tech Battery Breakthrough Could Revolutionize Mobile Computing

Far more than just a convenience, better battery technology would impact how our mobile devices are designed and how they behave. For example, Apple currently imposes numerous restrictions on members of their mobile device lineup for the sake of battery performance. On Apple iPhones, iPod Touches and the forthcoming iPad, applications aren’t permitted to run in the background and Adobe Flash technology has been banned altogether, supposedly for its CPU usage which rapidly drains battery juice. Other mobile smartphone makers, while not necessarily as restrictive as Apple, still have to weigh the benefits of providing these same types of features with the performance hit their gadgets will take if they do so. And as anyone who regularly fires up their smartphone web browser knows, too much Internet surfing during the day means a phone that dies out before nightfall.

bn nook logo oct09 Battery Breakthrough Could Revolutionize Mobile ComputingAnother example of the technology’s potential impact: e-Readers. Today, if you want to pack your Kindle or Nook device to take with you on vacation, you still have to go through the thought process: how long will I be gone? Will my battery last? Should I pack the cord? Now imagine that you could just throw your e-Reader into your bag without a second thought, just as if you were packing the paperback novel or newspaper these sorts of gadgets aim to replace. Would that encourage more people to make the switch from the analog formats to digital?

The Impacts of Better Laptop Batteries

What if, in the future, concerns like these were no longer a worry? What if phones, netbooks, e-Readers and other mobile devices could be used for days on end without the need for a charge? That would radically impact the way we think about and use our mobile devices.

There are a million other use cases that could benefit from this technology change, too, including sensor networks, computing from remote areas, faster news dissemination from areas impacted by disasters (either natural or man-made) where power outages have occurred, gadgets for hikers, campers and other explorers who spend weeks away from civilization and, therefore, away from electricity, mobile location-based services that run in the background on smartphones and other personal mobile gadgets and – OK, we’ll admit it – the ability to Twitter all day long without a recharge.

For the nitty gritty technical details about this new battery technology, MIT’s Technology Review explains everything from the cathodes to the conductivity as well as the challenges still ahead for this breakthrough technology. Most notably, the scientists still need to figure out how to maintain capacity. After five discharge/recharge cycles, the batteries lost one-third of their initial storage capacity and after 40 to 50 cycles, they ceased to function altogether. However, if the researchers can overcome that final hurdle and a few others, the new technology could one day become commercially viable. It’s too soon to know if that will actually occur, but as gadget lovers ourselves, we’re hopeful.

Sony new Vaio SA and SB-series with docking stations and battery slices

Sony is equipping its new Vaio SA-series and SB-series with docking stations and battery slices. The laptop battery life is going to double, and the annoying plugging in of power cables will be a thing of the past.
Sony laptop battery Sony new Vaio SA and SB series with docking stations and battery slicesSony Vaio VPC-SB1Z9EB with Battery Slice VGP-BPSC24 on the Docking Station VGP-PRS20

Who hasn’t stared jealously at the extensive docking and battery options available for the business class models from HP, Lenovo or Dell? Now Vaio users can profit from these features too. The mainstream consumer series, Vaio SA and SB, come with docking stations and battery slices, granting the user the ultimate battery life experience.

Docking Station VGP-PRS20

The docking station, VGP-PRS20 (about 129 Euros), uses a power adapter cable which is similar to that of the notebook (mixing the two up won’t cause any problems). As the user will have two power cables which serve the same purpose, he/she can leave the cable of the docking station plugged in during a trip for simplicity sake. The docking station can be used to recharge batteries (including the battery slice) and the slider on the right side allows the user to switch to “Extended Laptop Battery” mode.

The docking port offers HDMI, VGA, 4 USB ports (no USB 3.0; those are only available on the notebooks themselves) and 2 x RJ45 (LAN) ports. As soon as the Vaio is placed on the docking port, the HDMI, VGA and RJ45 ports of the laptop can no longer be used, and to prevent anyone from doing so, the docking station has two plastic flaps on the side which block these ports effectively.

The placement of the device does not involve the use of any latches or locks. This means: place the laptop on the two protruding bumps and you’re done. The subnotebook will not slip due to two securing hooks (silver) which stick out of the base unit and secure the model so that it doesn’t fall.

Battery Slice VGP-BPSC24

The VGP-BPSC24 battery slice is a flat battery (Li-Polymer, 6 cell), which fits under the base unit of the Vaio SA- and SB series models. It has a capacity of 4.400 mAh or 49 Wh (11.1V). The notebooks have have a connector on the bottom which allows them to attach themselves to the slice battery. However, this connector is not the same as the one found on the docking port. This additional battery slice VGP-BPSC24 costs around 130 Euros and weighs 520 grams.

During notebook use, the laptop batteries are designed in such a way that the slice battery will be used first. The slice battery can be charged via the notebook or  through a small charging dongle (while the battery is not connected), so theoretically, the 13.3 inch device can run the entire day without internet.

The black battery slice looks good when attached to the notebook, even though its colour only fits to that of the black Vaio SB. The latch has two metal hooks on the locking side. The holes for these hooks, on the other side, are made of synthetic material. To prevent an accidental unlocking, the security mechanism is two-fold (lock and release). The perpendicular hole in the middle of the slice battery is for the docking station (without this hole, the slice HP COMPAQ Business Notebook NC6400 Battery would raise the laptop enough to free the non-functioning ports).

Laptop Computer Battery Run time

For our test we used the series model VPC-SB1S1E/W with an i5-2410M processor. This model comes with a 50 Wh battery (4.540 mAh). We dimmed the brightness to roughly 100 cd/m² during our test. The CPU load was low while surfing on the web (no videos, only websites). One downside is that the charging of the duo packet (notebook battery + battery slice) takes a while: 5:46 hours.

WLAN-Test @50 Wh Standard: 314 minutes (5:14h)

WLAN-Test @50 Wh + 49 Wh: 648 minutes (10:48h)

Thanks to the docking station and battery slice, the user is spared the chaos of  cables all over the place, and the mobility is doubled. These two additional features are fully compatible with each other, which means that the Vaio notebook can still sit on the docking station, even if the slice battery is attached. These features are sure to immensely increase the comfort of the user, as both the Vaio SA (not available yet) and the Vaio SB can connect within one second to these peripheral devices.

How To Maximize Battery Life Of HTC Thunderbolt

thunderbolt battery life batteries company.com  How To Maximize Battery Life Of HTC ThunderboltEven though the HTC Thunderbolt didn’t make our longest-lasting smartphones list, that doesn’t mean owners have to settle for short battery life. It is possible to squeeze all-day power out of the phone. We’ve found a slew of simple things you can do to get more hours off the charger without making your phone pointless as a mobile computing device (that don’t involve a bulky battery).

Remember, the HTC EVO 4G had some longevity issues, too, and we suggested you check out these tips over at Good and Evo (25+ at last count) to make it last longer. Several of these apply to the Thunderbolt as well. The forum-goers over at Android Central have a monster thread about the topic. And, of course, we have our own (general) battery tips for Android phones. After mining these tips for my own Thunderbolt, I’ve been able to get 12 – 16 hours on a regular basis.

Here are the tips:

  • I lowered my default screen brightness to 25%. Your needs may vary, especially if you spend more time outdoors.
  • I leave my WiFi radio on constantly. This doesn’t drain much battery when it’s not within range of a network it knows and isn’t constantly searching for networks to connect to because I disabled WiFi notifications. This keeps the phone from updating me every time a network comes in range, which is every 3 feet in NYC. By leaving the WiFi on, I don’t have to remember to connect to a network when I’m at home or work or other places I frequent. This saves a lot of battery power.
  • I also changed the WiFi sleep policy to Never so that the phone uses WiFi (when connected) even if the screen is off.
  • I disabled Always On mobile data. All of my services still sync just fine. Background Data is still on.
  • I disabled data roaming. Most of the time I’m in a normal service area.
  • I usually turn off my screen when I don’t need it out of habit, so my screen timeout time is long — 5 minutes. However, if you tend to just leave your phone off to the side when you’re done, set this lower.
  • I’ve turned off auto-sync for services I don’t use (News, Stocks) and upped the sync interval for apps and services I don’t check very often. Be sure to go into individual apps that sync data to do this as well.
  • Every now and then I poke my head into Settings > About Phone > Battery > Battery Level to see what’s using the most power. Sometimes it’s a system setting or component, but sometimes it’s an app updating too frequently. Then I can adjust.
  • The only home screen widget I use is the HTC clock/weather app. I deleted FriendStream first thing.
  • I disabled “Movie Updates” in the BlockBuster app.

I didn’t condition or bump charge my battery, though that’s a step I might take in the future depending on how badly this battery degrades over time.

Anyway, this is just 10 things out of around 30 tips all told. I’m not sacrificing any functionality I desire, I’m getting all the data I need/want in a timely manner, and I have all-day battery life. Win. Check the sources for more tips to see which ones you can deploy to add some life to your Thunderbolt. And if you have any new battery usage tips, let us know in the comments!

Apple MacBook laptop batteries susceptible to hack attacks

Kristal Apple MacBook laptop batteries susceptible to hack attacksNow that Apple has endowed the Mac operating system with state-of-the-art security protections, a researcher has devised new attacks that target the machine’s battery.

Charlie Miller, well known for his numerous attacks on iPhones and Macs, may not have achieved his ultimate objective of making a Mac spontaneously combust, but he has figured out how to permanently disable the battery. And in time, he said, it also may be possible to remotely hijack a machine by manipulating the firmware on one of the stored power supply’s chips.

“What I found was you can make any change you want to the software that runs on the laptop battery,” Miller, who is principal research consultant at security firm Accuvant and the other coauthor of The Mac Hacker’s Handbook, told The Reg. “I also saw that you can mess up the chip so it won’t function anymore. You can’t recover from that. You couldn’t even take it to the genius bar.”

The flaw making all of this possible is the result of Apple’s decision to ship MacBook batteries without changing the passwords needed to run updates or make low-level changes to their embedded controllers. By reverse-engineering past updates, he had no trouble deducing the pass codes.

With these, Miller was able to make changes to the battery firmware that bricked the Apple a1175 battery. The hack doesn’t sound all that interesting until you consider that any changes will survive a complete reinstallation of the MacBook’s operating system. Miller theorized that if there’s a way to cause the firmware to exploit a vulnerability in Mac OS X, his laptop battery pack hack could open the door to system compromises that persist even after disinfection of reinstallation.

Miller will be presenting his findings at next month’s Black Hat security conference in Las Vegas. At his talk, he will also release a software tool that patches the vulnerability by changing the default passwords that ship with 15 inch macbook pro battery.
