6/5/2017 - Asus A52F Battery

The trackpad is sensationally sensitive, impressively large (127mm on the diagonal) and all your favourite multi-touch functions are of course possible. We think this trackpad is actually the Air's greatest asset -- we've never seen a laptop with a better trackpad, and it makes Web browsing and cruising around the Air's OS a real pleasure.The display is pretty impeccable, though at this kind of price you'd expect near-perfection. This 13.3-inch panel has a maximum resolution of 1,440x900 pixels, and it's extremely bright, clear and colourful. Rest assured, from family photos to HD movies, everything rendered on this display is liable to come out looking rather splendid.So what we have is a beautifully designed, highly usable and attractive machine. But let's be honest, those things were never the contentious issues. Let's get under the hood of the Air and see if we like what we find.Taking centre stage, we have a dual-core Intel Core 2 Duo processor clocked at 1.86GHz, with 2GB of DDR3 RAM and an Nvidia GeForce 320M graphics card waiting in the wings. That isn't particularly flashy hardware, so how does it actually perform?

Looking for a laptop to use on the move, but want one that's available in more than just business black? Sony may have the answer with its thin and light Vaio VPCY21S1E, which comes in a range of colours including blue, pink and silver. It won't break the bank, either, at just £650.Sony can usually be counted on to add a touch of style to its laptops, and that's certainly the case here. This is a beautiful machine that's not only small and light, but also manages to feel impressively sturdy for an ultra-portable. We had the blue version, which actually looked more teal-coloured to our eyes, but it certainly makes a refreshing change from the glossy black or grey finish you get on most of today's laptops. There are some neat design touches, too, including the slightly cut-away corners at the front and the chunky circular screen hinges. All the recent Sony laptops we've seen feature keyboards with an isolated design, and this model continues the trend. The layout is excellent and the slightly smaller function keys are the only compromise that has been made in terms of size. The keys have a good amount of travel, too. This, combined with the generous space between each key, makes it very easy to touch-type at speed without accidentally hammering adjacent keys.

We also like the roomy touchpad -- its matte finish allows your finger to easily glide across the surface. The two elongated trackpad buttons are also pleasingly responsive. As with many of today's laptops, the trackpad supports multi-touch, so you can use gestures like pinch-to-zoom in applications such as Windows Photo Viewer.Blimey, it's another netbook. While one more miniature laptop to add to the ever-increasing pile might not seem very exciting, if you like the idea of ultra-portable computing, you probably want to stay on top of what's new. Take a gander at our latest competitor, the Acer Aspire One D260-2Dkk -- yours for around £250.In terms of design, you'll find a subtle square pattern on the D260's black gloss lid. This extends to the interior, too, covering the chassis and surrounding the keyboard. We think it looks pretty cool, and a little Tron-esque, but if you like bright colours, there's not much here for you.

The D260 certainly has a slender silhouette. It weighs just 1.25kg, which is certainly on the lighter side. Concentrate really hard and you can almost conjure up a mental picture of the D260 when we tell you it measures in at 259 by 185 by 24mm. It's plenty skinny, and definitely slim enough to hurl into your satchel or handbag if you're dashing out. An interesting angular pattern covers the lid and interior of this netbook.The display is a 10.1-inch affair, with a resolution of 1,024x600 pixels. We've seen the odd netbook with a higher resolution than that, but to be honest this is pretty much par for the course. At least this display is bold and bright, with sufficiently vivid colours.Where netbooks usually fall down is usability, packing cramped keyboards and uncomfortable trackpads into a tiny chassis. Often they're so frustrating to use, we want to fire them out of a trebuchet into a stony castle wall. We're glad to report that the D260 doesn't suffer too badly from these common afflictions.

The keyboard extends right up to the edge of the chassis, and the whole thing is sensibly laid out. We typed on this keyboard for an extended period of time and found that, although each key offers little travel, this was actually a pretty comfy keyboard to use, with nothing driving us particularly crazy.Apple has refreshed the top-end Pro models in its MacBook range of laptops. A wider range of processor options is now available, as well as battery-saving graphics-switching options and an HDMI-friendly DisplayPort update.The 15-inch MacBook Pro can now be bought with 2.4GHz or 2.53GHz Intel Core i5 processors for £1,500 or £1,650 respectively. The model with a 2.66GHz Core i7 chip costs £1,800.The 17-inch model also offers a 2.53GHz Core i5 chip, for £1,900. Models of both sizes now include Nvidia GeForce GT 330M graphics with 256MB or 512MB of RAM.

Graphics-intensive programs like Aperture or games will run up to 80 per cent faster, Apple claims. Your battery won't be constantly caned either, thanks to a new automatic graphics-switching technology. This uses multiplexer hardware to turn the discrete graphics chip off when it's not needed. If you're out and about and need to squeeze every drop of juice out of the battery, you can opt to stick with just the integrated Intel graphics processor instead of switching to the power-sucking dedicated chip.Unlike Nvidia's similar Optimus technology, multiplexer hardware can result in a screen flicker when switching between the integrated and dedicated graphics processors. We'll try out the new models to see if Apple has solved that problem just as soon as we get our hands on them.The 13-inch MacBook Pro has increased its battery life to ten hours and added an Nvidia GeForce 320M graphics processor, alongside the existing 2.4GHz or 2.66GHz Core 2 Duo chips. It starts at £1,000 for 250GB of memory, or £1,250 for 320GB.

Trackpads now support inertial scrolling, which allows you to flick the pad to send the page scrolling, as on the iPhone. The mini DisplayPort also supports audio output, meaning you can plug your new MacBook Pro into a high-definition television with just the one HDMI adaptor, instead of needing a separate cable for sound.Will these updates convince you hardcore gamers to get yourself a Mac? Let us know your thoughts in the comments section below.

Bargain.While it's not technically an ultrabook, the m6 is no monster. It sports a reasonably slim chassis and feels light enough to carry around all day without too much strain. The look of this laptop is similar to the recently-unveiled HP Envy Ultrabooks and Sleekbooks, but there are some minor differences.Netbooks may have lost some of their sheen given the rise of tablets, but that hasn't stopped Sony throwing a new mini laptop into the ring, the Vaio VPCYB2M1E. This 11.6-inch cutie is certainly portable and it packs decent specs by netbook standards. At £430, it's not cheap, though.

The Y series is Sony's elite netbook, spitting on the lower-end Vaio M series VPCM13M1E. We're not too keen on the M series refresh this year, but the Y series promises to be a much stronger performer, pushing the boundaries of what can be described as a netbook.The 11.6-inch screen makes it a very small little chap, measuring only 290mm wide. This means it's small enough to fit into even the most modest backpack, while still leaving room for sandwiches, a Frisbee and an air horn (is it just us?).The lid proudly displays the Vaio branding, but little else -- the minimalist Vaio aesthetic has been retained, making this an attractive piece of kit. The chassis is made from sturdy plastic, which is good news for a machine that's designed for intense mobile use.The 11.6-inch display has a maximum resolution of 1,366x768 pixels, so it's able to display Web pages without any problems. It's pretty bright too and handles colours well. Reflections didn't seem like much of an issue during our brief hands-on session, but, if you regularly use the machine outside in bright sunshine, you might find yourself staring back at your own face more than you'd normally like.

Thanks to our trusty 50p piece, you can see the machine's backpack-friendly size. The isolated keys on the keyboard are pleasant to use and it's good to see Sony using all the space at the sides of the chassis to make the keyboard as large as possible. It's not a backlit keyboard, so sitting in bed at night browsing your friend's Facebook pages is going to be tricky without the lights on. Alas, the trackpad is on the small side -- you may find you have finger ache after a long scrolling session.Port options are pretty standard. There are three USB 2.0 ports; Memory Stick Duo and SD card slots; Ethernet, VGA and HDMI sockets; and headphone and mic jacks. There are internal speakers too, but we don't expect they'll be very powerful. We'll see how they sound when the Y series lands in our office.Typically, netbooks have just about enough computing power to load Windows calculator. The Y series has somewhat more junk in the trunk, though, which is why Sony is keen to tell everyone that it isn't really a netbook. It is, though, Sony -- it's just a powerful one.At the heart of this little machine is a dual-core, 1.6GHz AMD E-350 processor, coupled with 4GB RAM. That's a considerable increase over the M series' components -- a single-core, 1.83GHz Intel Atom N470 processor and only 1GB of RAM. We therefore expect the Y series to post considerably better scores in our series of benchmark tests.

This time our iPhone 4 provides scale. It looks like we've received a Twitter message! With those specs, you can easily expect the Y series to handle all manner of office tasks and maybe turn its hand to some light photo editing and video streaming. Although you wouldn't need to stream at 1080p on such a small screen, the HDMI output will allow you to stream video to a TV, so we'd like the machine to be powerful enough to play video at this quality.Don't expect the VPCYB2M1E to be much of a gaming machine -- it doesn't have a dedicated graphics chip. Most netbooks are typically designed purely for Web browsing and document editing on the go anyway, so we can't be too disappointed.Sony claims the Y series netbook can achieve up to 6.5 hours of battery life, which is a reasonable figure. We'll see how Sony's claim holds up when a review sample lands in the office and we can punish the battery to breaking point.
