IBM ThinkPad R40 Battery

Rumbling inside the G750JZ is some of the most high-end core hardware weâ€™ve seen in a laptop. Thereâ€™s a 2.4GHz Core i7-4860HQ supported by 16GB DDR3 RAM and accompanied by a 1.5TB hard disk and 256GB SanDisk SSD. As we expected from such an impressive hardware array, the Asus laptop had no problem zipping through our suite of Real World Benchmarks, and it smashed its way through with a potent Overall score of 0.98.Predictably, the G750JZ also proved itself to be a gaming powerhouse; armed with its Nvidia GeForce GTX 880M dedicated GPU equipped with 8GB of GDDR5 RAM, the demands of Full HD gaming barely saw it break a sweat. In our Crysis benchmark, with graphical detail set to its very highest setting, the Asus whipped through the benchmark at an average of 58fps. Suffice it to say, thereâ€™s plenty of power in reserve ready and waiting for the toughest gaming titles.

With that amount of heavy-duty hardware running, we were expecting to run into problems with overheating and poor battery life, but we neednâ€™t have worried. The intake and exhaust fans do a good job of keeping the system at a manageable temperature: thrashed by stress-testing programs such as Prime95 and FurMark, the cooling system kept the CPU at 80ËšC and the GPU topped at a positively 82ËšC. The removable 5,900mAh battery was no underachiever, either, and with the display dimmed down to 75cd/mÂ², the Asus lasted 7hrs 46mins in our light-use battery test.The only disappointment in the Asusâ€™ benchmark figures is due to its SSD. We were a little surprised at how poorly it performed in the AS SSD benchmark, with sequential read and write scores of 283MB/sec and 216MB/sec respectively. Weâ€™d expect almost double that from the best SSDs weâ€™ve seen, and weâ€™d expect the figure to triple in the case of Appleâ€™s PCI Express-based SSDs. However, in real-world use the Asusâ€™ combination of solid-state and mechanical drives works with aplomb; we timed the G750JZ performing a cold boot to the Start menu in just over six seconds. And since itâ€™s possible to access the Asusâ€™ pair of 2.5in drive bays by unscrewing a panel on the underside, itâ€™s always possible to upgrade to a faster pair of drives in the future.

Asus has also made sure that the G750JZ is equipped with oodles of connectivity. The most notable inclusion is the single Thunderbolt 1 port â€“ the G750JZ is the first non-Apple laptop weâ€™ve seen to include the standard. There are also four USB 3 ports, an SD card reader, HDMI and D-SUB outputs, and Gigabit Ethernet. We were also pleased to note that, along with Bluetooth 4, the Acer laptop touts dual-band 802.11ac Wi-Fi. However, the G750JZ does have one major Achilles heel: Asus has plumped for a lower-quality display than we were expecting. The 17.3in 1,920 x 1,080 TN panel gave a reasonable performance when tested by an X-Rite colorimeter: the LED backlight topped out at 277cd/mÂ² and contrast ratio measured 595:1. Gamers will appreciate the screenâ€™s matte anti-glare coating, too.

Closer inspection revealed more serious issues. Vertical viewing angles are narrow; the Asusâ€™ panel crushes the darkest greys into black; and our test images were cast with anaemic, unnatural-looking colours. Further testing with our X-Rite colorimeter pinpointed the issue: the panelâ€™s average colour accuracy reached a highly unimpressive 5.55, a result that indicates most onscreen colours are some way away from their intended shade. For the most part, we were extremely impressed with the Asus ROG G750JZ. Itâ€™s by no means cheap, but it sports some of the finest mobile components money can buy, and for considerably less than similarly specified machines from rival brands such as Alienware. That said, we simply canâ€™t excuse such a mediocre display on an £1,800 laptop. With a better display, the Asus ROG G750JZ would be a tour de force, but as it stands, weâ€™d sacrifice all-out power and plump for the MSI GE70 2PE Apache Pro â€“ itâ€™s by far the better all-round machine.

Using Leap Motion to navigate Windows 8 was a frustrating experience for our reviewer, and there are other downsides: according to The Verge, Leap Motion significantly reduces the Envy's battery life.The Leap Motion controller itself costs £63 exc VAT at retail, so isn't likely to have bumped up the price of the laptop too much, with comparable versions of the Envy 17 coming in at the £999 mark.Aside from the controller, it also features a 17.3in Full HD touchscreen display, 4th-generation Intel Core i7 chip, 8GB of RAM, a 1TB HDD and optional Nvidia graphics.HP also unveiled the passively cooled Spectre x2 hyrid Ultrabook. The Spectre x2 has a detachable display to be used as a tablet, and as it doesn't require a fan, it has "no noisy hardware or unsightly vents", HP said.The HP Spectre x2 features a 13.3in, 1080p display, and runs Intel's 4th-generation Core i5 chip. It will arrive in the UK in November for £999.

Asus has been producing its Transformer Android hybrids for years, but the TF103C breaks new ground for the company. Where previous efforts have been pitched at the premium end of the tablet market, to compete with Apple's iPad and models such as the Sony Xperia Z2 Tablet, this latest effort is firmly targeted at the lower end of the scale, where products like the Nexus 7 hold sway. The Transformer Pad is no 7in titch, however. It's a full-sized 10.1in slate that turns into a compact laptop with the addition of a keyboard dock. And it costs a mere £199, with the dock adding £40. That makes it a bit of a bargain.Despite the low price, the TF103C doesn't feel cheaply made. The tablet is solid, with a rubbery plastic coating on the rear giving it a grippy feel under the finger, and firm power and volume buttons on the top and left edges lending it a sense of dependability.The keyboard dock â€“ an essential purchase we think â€“ is endowed with similar qualities. It's made from tough plastics, and both the keyboard and touchpad work without fuss. The keyboard in particular is a triumph, with a sensible layout and keys that have plenty of travel and give positive feedback.

What you're not getting here is the lightest or slimmest tablet around â€“ the tablet weighs 556g and measures 10mm thick, and the dock takes that up to 1.1kg and 23mm â€“ but it's hardly going to kill you to carry it around in a bag. There are benefits to lugging the keyboard around, too, since it adds a full-size USB socket to the tablet's microSDXC slot. Unlike the firm's other Transformer Pad devices, however, there's no second battery built into the base.You knew it was coming: to keep such a tight lid on the price there have to be compromises, and the screen is the first victim here. The TF103C comes not with a 1080p screen, but a 1,280 x 800 one, a resolution we thought we'd waved goodbye to on all but the cheapest tablets. Images inevitably have a more pixelated look to them than, say, the Sony Xperia Z2 Tablet, and text doesn't have that print-on-paper sharpness we've come to expect from the best tablets.On the flip-side, that pixelated image looks bright and bold. The display reaches a maximum brightness of 407cd/m2 and a contrast ratio of 1,018:1, both of which are excellent figures, and to add to its achievements the glass also has a fingerprint-resistant coating. We found it still picked up the odd greasy dab, but the coating makes it easy to clean with a soft cloth or a quick wipe of a shirt tail.

It's tougher to overlook the poor cameras. Both the rear 2-megapixel camera and the front-facing 1.2-megapixel webcam are dreadful in every sense of the word. Photographs lack detail; videos are captured at 720p, but are horribly noisy even in brightest of light.Asus has gone all Intel with its latest clutch of budget Android tablets, and this hybrid is no different. At the helm is one of the latest Bay Trail processors - a 1.33GHz quad-core Intel Atom Z3745, accompanied by 1GB of RAM and 8GB or 16GB eMMC storage â€“ and its performance is spritely. In the SunSpider JavaScript benchmark, a time of 610ms marks out the TF103C as one of the fastest tablets on the market, not far behind the much more expensive iPad Air and Samsung Galaxy Note Pro 12.2. Its results in Geekbench 3 are equally impresive, with scores of 757 and 2,334 in the single- and multi-core tests and a frame rate of 28fps in the demanding GFXBench T-Rex HD gaming test. It's as quick as any tablet we've tested.

We had absolutely no complaints about performance in general use, either: the TF103C coped with everything from web browsing, through word processing to gaming and barely broke sweat. It runs Android 4.4, so you have the latest software to play with, too.Inevitably, Asus has tinkered with the UI, but it isn't too intrusive. The main thing you'll notice is a rejigging of the pull-down notifications menu, which looks a lot like that found on the Samsung Galaxy S5 smartphone â€“ complete with pale green pastel colours and circular shortcut buttons. Otherwise, the tweaks are confined to a selection of preloaded Asus apps. Battery life is this tablet's one weakness. In our looping video battery test it lasted 8hrs 21mins, which is below average for this class of tablet. It should get you through over a day of use, though.Until now, if we had been asked to recommend a budget tablet, we'd have plumped for the Nexus 7 straight away, but the Asus Transformer Pad TF103C has given us another option. For fans of large-screened tablets who might want to do a touch of work on the move, its performance, display quality and usable keyboard make it a worthy alternative.http://www.batteries-pc.com/samsung.html

Asus knows how to build a brilliant cut-price laptop â€“ take a look at its 11.6in VivoBook X200CA and 10.1in Transformer Book T100 if you donâ€™t believe us. But its X552CL takes on the challenge of putting together a more powerful 15.6in system while still managing to keep down the cost. With a Core i5 processor, Nvidia graphics and a sensible range of features for £400, it looks like Asus may have nailed the formula. See also: what's the best laptop you can buy in 2015?This isnâ€™t a laptop to set the pulse racing: the X552CLâ€™s exterior is cast entirely in sombre, matte-black plastic. The only note of visual interest is a textured chain-link finish that stretches across the lid and wristrest, and a fake, brushed-metal effect on the keyboard panel. Itâ€™s inoffensive, though, and while the 2.27kg chassis doesnâ€™t ooze the rock-solid charm of pricier models, it feels well put together, with the base remaining firm despite its slim profile. If thereâ€™s a weak point, itâ€™s the plastic-covered lid, which flexes more than weâ€™d like: if youâ€™re tempted to carry the X552CL on your travels, consider investing in a padded laptop bag.
