Toshiba PA3728U-1BRS Battery

"Our battery produces about half the voltage of a typical lithium battery,â€ said Stanford professor Hongjie Dai in a press release. "Improving the cathode material could eventually increase the voltage and energy density. Otherwise, our battery has everything else youâ€™d dream that a battery should have: inexpensive electrodes, good safety, high-speed charging, flexibility and long cycle life. I see this as a new battery in its early days. Itâ€™s quite exciting.â€Dai is right, this is "quite exciting", but will it actually be the future of battery technology?Battery breakthroughs take time to trickle down into manufacturing, and with rapid advancements in current battery technology, these discoveries could easily be eclipsed. Earlier this year we heard that vacuum-cleaner company Dyson had invested $15 million into a solid-state battery company Sakti3, which is already making strides in the technology.

Apple may be using liquid electrolytes for its incredibly thin and light MacBook, in doing so it's managed to create a laptop with impressive battery life for its size. If research into liquid-free polymer lithium-ion batteries makes strides, the risks associated with lithium-ion batteries will melt away.MacBook polymer lithium-ion battery
We also know that the University of Manchester has invested heavily in graphene technologies. Graphene battery technology could be smaller, lighter and more durable than its lithium-ion counterparts, while also being larger in capacity.So while this aluminium-ion battery may be a breakthrough, it seems like it will be no more than a stopgap. Lithium-ion technologies are advancing rapidly, and graphene research is also improving at breakneck pace.

Most tellingly of all, Tesla and SpaceX founder Elon Musk isn't convinced by Stanford's breakthrough. On Twitter he let his feelings be known â€“ although it may be worth taking with a pinch of salt, due to his plans for revolutionising lithium-ion battery technology for his electric car brand.The Slatebook 14, the full specs of which were leaked back in April, is a 16mm thick notebook with a 14in, 1080p Full HD touchscreen and integral keyboard.It also features an Nvidia Tegra 4 mobile processor, and integrated GeForce GPU and, HP claims, has up to nine hours of battery life.It's not the first HP laptop to run Android. The Slatebook x2 hybrid was released last year, but had a lower resolution 10.1in screen.The Slatebook 14 also has a USB 3 port in addition to the USB 2 that was available on the Slatebook x2, and runs on Android 4.3 (Jellybean), rather than 4.2.2.Despite Apple's recent acquisition of Beats, the Slatebook 14 still features Beats audio - indeed HP has pledged to continue using the technology into 2015.

The company also revealed the HP Envy x360, a Windows 8.1 laptop that can flip between a tablet and a notebook thanks to its 360 degrees hinge.As with the Slatebook 14, it builds upon the previous Envy x2 model, which was also released last year.Like the Slatebook 14, it has a bigger screen than the Envy x2 - 15.6in compared to 11.6in - which is Full HD, compared to the Envy x2's 1,366 x 768 resolution.The Envy x360 also features an Intel Core processor, rather than its predecessor's Intel Atom.The Envy x360 will be available in the UK in August with a starting price of £649. The Slatebook will be available in the UK in late July, and has a starting price of £329.It was Windows 8 that finally killed the netbook. After several years of success, the disappearance of Windows 7 Starter Edition resulted in the supply of miniature, ultra-cheap Windows portables suddenly drying up, a gap Google was happy to fill with its Chromebook concept. Undeterred, Microsoft has fought back with a surge of low-cost compact tablets and hybrids, and now the Toshiba Satellite CL10-B is the first in a new line of cloud-focused Windows laptops.

In many ways, the Toshiba Satellite CL10-B is the spitting image of a Chromebook. Itâ€™s finished in a combination of matte and gloss grey plastics, and for a £200 laptop, itâ€™s surprisingly smart and attractive. It weighs a dainty 1.1kg, and the compact 11.6in chassis means itâ€™s the perfect size for popping in a bag and carrying around every day. It even feels like it will survive a good few years: build quality is excellent, and the sturdy-feeling base, strong-feeling hinge and overall solidity are reassuring.The other key similarity to a Chromebook isnâ€™t readily apparent, but Toshiba has kept costs down by opting for a tiny 32GB of eMMC storage, a decision that leaves only 14GB free after the operating system and recovery partition have taken their share. This may sound like a deal-breaker, but just like every Chromebook, the Satellite CL10-B also comes bundled with 100GB of storage courtesy of a two-year Microsoft OneDrive subscription. After the two years are up, youâ€™ll need to pay £1.99 per month to keep that level of storage or it will drop to 15GB; alternatively you can choose to upgrade to the 200GB or 1TB plans for £3.99 and £5.99 respectively.

Unlike some of the low-cost Windows devices weâ€™ve seen, such as the Asus Transformer Book T100, the Toshiba isnâ€™t bundled with a free copy of Microsoft Office. But since every OneDrive account (yes, even unpaid ones) includes access to Microsoftâ€™s Office Online suite, you wonâ€™t have to shell out for an office suite to create or edit documents in Word, Excel, OneNote and PowerPoint â€“ as long as youâ€™re within reach of a Wi-Fi network, that is. Of course, you can always stick with Google Docs if you prefer.Itâ€™s here that the Chromebook similarities end. This laptop isnâ€™t running a cut-down, cloud-only version of Windows. Instead, the operating system of choice is Windows 8.1 with Bing, the low-cost OEM version of Microsoftâ€™s OS. But for the fact that Bing is selected as the default search engine in Internet Explorer, and that Microsoft is virtually handing it out free to manufacturers, it lacks none of the features of proper Windows 8.1: itâ€™s a fully featured 64-bit desktop OS.

Fire up the CL10-B and, while first impressions arenâ€™t amazing, it does begin to grow on you. The Scrabble-tile keyboard lacks feel, with keys that have barely any travel at all, but in practice itâ€™s easy to get used to. We quickly forgot about the feel and found ourselves tapping away at full-speed without any problems. The touchpad, too, is unexceptional, but it works. Our only complaint was that we found it a little too easy to activate Windowsâ€™ edge-swipes by accident.Toshiba Satellite CL10-B review: performance and battery life Toshiba hasnâ€™t cut many corners on the hardware inside, either. It has an Intel Celeron N2840 and a dual-core CPU that runs at 2.16GHz and, while the 2GB of RAM isnâ€™t upgradeable, the Bay Trail CPU and nippy eMMC drive keep Windows feeling surprisingly spritely for such a low-end machine.

In our Real World Benchmarks, the Toshiba achieved a modest 0.36 overall. It doesnâ€™t feel particularly slow in practice, and this is due to the Toshiba eMMC drive â€“ in the AS SSD benchmark, it achieved decent sequential read and write speeds of 169MB/sec and 58MB/sec respectively. Bear in mind, though, that the minimal amount of RAM and modest CPU arenâ€™t sufficient for any serious multitasking or heavyweight applications. Things start to lag a little when you push it too hard.The flipside, however, is that battery life is excellent. A 28Wh, 3,684mAh battery is sealed behind the CL10-Bâ€™s base panel and, with Wi-Fi disabled and the screen brightness dimmed to 75cd/m2, it kept the Satellite CL10-B going for 9hrs 2mins. The bad news is that the battery isnâ€™t easy to get at, although itâ€™s technically replaceable if you remove ten screws and prise off the plastic underside â€“ it should be possible to get replacements from Toshiba a few years down the line if you need to.

In other areas, the Satellite CL10-B throws up few surprises. The 11.6in display has a bog-standard 1,366 x 768 resolution and, while the TN panel has typically narrow vertical viewing angles, image quality is acceptable. The range and accuracy of onscreen colours isnâ€™t wonderful â€“ it covers a mere 62.8% of the sRGB colour gamut for starters â€“ but brightness reaches a very respectable 273cd/m2, and the contrast ratio of 363:1 is better than most budget laptops.The features list is understandably frugal, but most of the essentials are there. Wireless connectivity stretches to single-band 802.11n and Bluetooth 4, and Toshiba has squeezed in full-sized HDMI, USB 3 and an SD card reader on the left-hand flank, plus a USB 2 port and 3.5mm headset jack on the right. Thereâ€™s also a 0.9-megapixel webcam that, while fairly scratchy and pixellated, is plenty good enough for video chats and so forth.http://www.batteries-pc.com/fujitsu.html

Ultimately, the Toshiba Satellite CL10-B finds itself going toe to toe with a talented team of Chromebooks, several of which offer better-quality screens or snazzier designs. Where the Toshiba trumps them all, though, is versatility. As Windows 8 removes the need to rely on web apps and a decent Wi-Fi connection, the Satellite CL10-B will be a more appealing buy than a Chromebook for many people. For only £200, this little ultraportable is well worth considering.Alienware has come a long way since it first landed back in 1996. Long gone are the days of luminous-green laptops and desktop PCs adorned with giant alien skulls; thankfully, the Alienware family has evolved into a far more tasteful breed, and the Alienware 17 is the latest evidence of that progression.If youâ€™re going to spend the best part of £2,000 on a gaming laptop, then you want it to look good, and here the Alienware 17 delivers. It oozes heavyweight class, with its body finished in a premium-looking palette of soft-touch matte black and gunmetal grey.
