Asus K53TA Battery

The trackpad doesn't have the eye-assaulting disco effect present on some of HP's other new machines. Instead your eyes and digits are treated to a more standard black trackpad.Number crunchers will appreciate the number pad, which has been spared the cut, despite the relatively small size of the laptop. A very promising sign is that the click buttons seem to be separate from the touch-sensitive portion of the trackpad. HP has a nasty habit of incorporating buttons into its trackpads, which means you often end up nudging the cursor off course when you try to click.There's not much about the m6 that's likely to get your blood pumping, but if the decent design is matched by solid performance and battery life, this could prove a dependable laptop. Starting at just shy of £600 it's at the upper end of the mid-range scale, so we'll be looking for plenty of processing grunt and impressive battery life when it comes to the full review.After two reports of flaming laptop batteries, the Consumer Product Safety Commission announced Thursday that Hewlett-Packard is voluntarily recalling 70,000 lithium-ion batteries that shipped with several models of its HP and Compaq laptops.

The recall affects nine models of HP Pavilions, nine models of Compaq Presarios, two models of HPs, and one HP Compaq laptop model sold between August 2007 and March 2008. For the full list, see the CPSC's site.There were two separate reports of batteries that "overheated and ruptured, resulting in flames/fire that caused minor property damage" but no injuries, according to the CPSC report.HP is instructing consumers who may be part of the recall to remove the battery from their notebook and contact HP to find out if theirs is affected. HP says it will provide a free replacement battery. For more information, see HP's Battery Replacement Program site.Palo Alto, Calif.-based HP is the world's largest computer vendor, and like many of its peers in the industry has been part of several similar battery recalls. The most recent incident involved 100,000 Sony-made batteries faulted for overheating late last year. HP had sold 32,000 of the affected batteries in its laptops. But that was tiny by comparison to the massive recall caused by Sony batteries in 2006.

Pressure from Apple's MacBook Air has sent the PC industry into a spiral of thin-and-light craziness. HP's getting in on the action too, with a new skinny machine called the HP Envy Sleekbook. Powered by AMD and coming in 14 and 15.6-inch sizes, I've been hands-on with the Sleekbook ahead of its launch. Read on for my first impressions.The HP Envy Sleekbook will be available in the UK from July, with prices kicking off at £549. Expect the cost to jump up if you opt for the 15.6-inch version. The images above are of the 15.6-inch edition, but check out our hands-on with the 14-inch HP Envy Ultrabook for an idea of what the smaller version looks like.The Sleekbook is exactly like an ultrabook -- in fact this machine is visually identical to the HP Envy Ultrabook, which also comes in 14- and 15.6-inch options and was announced at the same time. But Intel owns the 'ultrabook' name, and since these PCs are powered by AMD chips, HP has cunningly gone with 'Sleekbook'.

Crafty. But the Sleekbook has a starting price £100 lower than the HP Envy Ultrabook, making this a potentially more tempting proposition.To be brutally honest, using the terms 'ultrabook' or 'sleekbook' to describe this laptop is slightly misleading, as while it's reasonably thin at 19.8mm, the Sleekbooks are nowhere near as skinny or classy as the wedge-shaped MacBook Air, or even HP's own Envy Spectre XT.Take heart though -- the Sleekbook is still reasonably slim, and for a mid-range laptop it feels decently portable. Having a mildly bulkier chassis also makes room for more ports, which are detailed further down.The rectangular styling Sleekbook looks decent enough, though the plastic chassis doesn't exactly ooze class. There's a brushed metal effect on the lid and keyboard surround, which clashes with the black gloss that surrounds the display. The screen itself packs a respectable 1,366x768 pixels.

The version in the photos above is red and black, though a silver version was also on show -- fingers crossed a selection of hues make it to the UK.Like other HP laptops, the Sleekbook has speakers provided by Beats Audio. As such, there's a small lower-case 'b' sitting on the speaker grille.The keyboard sits within a recessed part of the chassis, with a healthy space between keys that should keep typing errors to a minimum. Helpfully, it's also backlit, which means you can keep on writing once the lights go out.The trackpad has a psychedelic, swirled metal look, that I wouldn't exactly describe as demure, but at least it's different to most trackpads. Unfortunately, HP is still making the click buttons part of the touch-sensitive surface, which means you'll likely end up nudging the cursor by accident when you try to click on things. There's a hearty port selection on show here. The left side plays host to an Ethernet port, HDMI out, two USB ports and an SD card slot -- handy for yanking photos off your digital camera.Spin the laptop around and along the right you'll find two 3.5mm sockets for a microphone and headphones and another USB port, which makes three in total -- one of which is USB 3.0.

There's 500GB of storage on an HDD hard drive with 32GB of SSD cache on the 15.6-inch version, while the 14-inch model has a 320GB HDD. Hybrid mechanical and solid state hard drives will be an option, or you can upgrade to an SSD drive. Expect that to make the Sleekbook more expensive -- although it might be worth the extra pennies. Solid state drives are better because they're faster than their mechanical counterparts, and lack moving parts, so are less susceptible to knocks.The SD card slot is useful for whipping holiday snaps off your camera and onto Facebook, where your ungainly knees will attract the requisite ridicule. I'm excited to see what performance the AMD chips inside the Sleekbook can deliver -- we'll know for sure once we get this PC into our testing lab, so stay tuned.The design of the Sleekbook doesn't exactly feel all that sleek, but I'm intrigued by the price. Starting at £549, if performance and battery life are up to scratch, this could be a great value machine.

Editors' note: Luke Westaway saw the HP Envy Sleekbook at an HP event in Shanghai. His flight and accommodation were paid for by HP, but the company had no input into the content of this article.

Palo Alto, Calif.-based HP is the world's largest computer vendor, and like many of its peers in the industry has been part of several similar battery recalls. The most recent incident involved 100,000 Sony-made batteries faulted for overheating late last year. HP had sold 32,000 of the affected batteries in its laptops. But that was tiny by comparison to the massive recall caused by Sony batteries in 2006.In the case of the Lenovo IdeaTab S2, we're seeing an Android 4.0 tablet converging with the keyboard and touch pad of a conventional notebook computer. Like Asus' Eee Pad Transformer Prime, the IdeaTab S2 comes as two separate, interlocking pieces: a tablet and a keyboard dock. It's a great combo for anyone who feels that their tablet needs to do more than just Angry Birds and Web browsing and actually serve as a tool for working and communicating.The keyboard accessory also provides a number of useful extras, such as two full-size USB ports, HDMI output, SD card reader, and an internal battery pack that affords an extra 10 hours of uptime.

With a press of a button, the tablet springs out (expertly demonstrated in this video) and you find yourself holding a slim (8.69mm) tablet with a 10-inch IPS display, boasting a 1,280x800-pixel resolution. The tablet runs Android 4.0 powered by a Qualcomm 8x60A/8960 1.5 GHz Dual Krait processor and 1GB of LP-DDR2 memory.The rest of the hardware capabilities are just as you'd expect from a high-end Android tablet, including GPS, 802.11n Wi-Fi, Bluetooth 2.1 + EDR, a 1.3 megapixel front-facing camera, and an 8-megapixel camera on the back that includes autofocus and an LED flash. There's also a microSD card slot for extra storage, Micro-HDMI output, Micro-USB sync, and an optional SIM card slot.Finally, to put its own spin on Android 4.0 (for better or worse) Lenovo has skinned the UI with a unique tiled interface, allowing you to quickly access frequently used apps and widgets (such as stocks and weather).

No word yet on exact availability, but Lenovo sounded optimistic that the tablet would arrive in the second quarter of 2012 with a base price of $399.While some of Apple's new laptops are built with internal batteries to increase power capabilities, other systems still have easily removable batteries. In similar systems, the batteries are interchangeable, and while it may be obvious that you can swap batteries among these systems, some people may also have concerns about doing this. Some of these might include whether or not the system would read battery status properly and if charge values would be similar across multiple machines."Since I own two batteries for my Intel Core Duo MacBook Pro I was wondering... where is the battery condition information stored, in the battery or the computer? The reason I ask has to do with conditioning/calibrating the batteries. If I successfully calibrate one battery and then do the same for the second, can I swap batteries and be confident the calibration will be accurate for whichever battery I am using at the time?" Battery calibration adjusts the battery itself, and not the computer's reading of the battery. A full calibration pushes the battery to its limits and resets the output levels that the battery tells the computer is 100 percent of its capabilities. As batteries age, they lose their ability to hold a full charge, so what is considered "full" for a given battery needs to be reset periodically.
