Asus k50in Battery

ThinkPads seem to be undergoing a design evolution that's slowly seeping into the whole product line. The Edge series was the start of the ThinkPad redesign, introducing a new, modern raised island-style keyboard and larger touch pad, along with a sleeker chassis. While recent laptops including the ThinkPad X1 have also appropriated this new look, we find the Edge series comes off slightly more relaxed.Earlier in 2011, we reviewed the IdeaPad U260, a stylish Lenovo consumer-oriented laptop with slick looks and a 12.5-inch screen, but an underwhelming battery. The ThinkPad Edge E220s offers a newer, faster CPU, a better battery, and nearly the same size and feel.The ThinkPad Edge E220s is covered top to bottom with a rubberized finish that's soft to the touch, similar to that of the IdeaPad U260 and ThinkPad X1. While the E220s looks like it is black at first glance, under the right light it looks like a very, very dark green. It's a different tone than the keyboard, which is true black. A chromed plastic edge lines the top lid and the keyboard deck, highlighting the curved lines around the front lip.

Inside, the keyboard-to-palm-rest proportion seems perfect: a full raised keyboard isn't quite edge-to-edge, but doesn't waste space, while the palm rests flank a medium-size square multitouch click pad. The glossy 12.5-inch display is covered with edge-to-edge glass, and it looks sharp: it's a clean overall effect. However, the Edge has a little more flex and plastic in its chassis than the tanklike roll-cage construction of the ThinkPad X1. It's a different product--the X1 is more expensive and a larger laptop--but it bears mentioning. The Edge E220s is a perfect marriage of size and design for its weight class; this is the sort of laptop we'd prefer to carry in our bag on a daily basis.We're big fans of the ThinkPad Edge keyboard design, and the E220s' keyboard feels as good as we remember. Lenovo's variation on the raised keyboard uses slightly concave keys, which offer a more centered feel when typing fast. The ThinkPad X1 had a similar keyboard that felt a bit crisper, but we found typing on the Edge E220s to be a breeze. Instead of a backlit keyboard, the E220s has a small overhead LED light that shines down from the upper lid (which some ThinkPads have had for years) to illuminate the keyboard and surrounding area. It's actually a very smart idea for plane travel--it's cozy, like a book light for ThinkPads.

Similarly, the improved click-pad design on this ThinkPad Edge solves the reduced finger-space problem introduced by the red rubber trackpoint and its included discrete buttons. The red nub, a perennial ThinkPad offering, isn't something we use, but some business travelers swear by it. That red nub sits between the G, H, and B keys on the keyboard, but the addition of three accompanying physical buttons below the space bar used to crowd the track pad when it, too, used discrete buttons. Now, the free space feels better proportioned. The smooth click-pad surface responds well and has cleanly clicking zones on the bottom, although it collects fingerprint smudges.A fingerprint reader on the right palm rest can be set to any finger for biometric log-ins without passwords. The rest of the interior of the Edge E220s is button-free, with the exception of the power button on the upper right. Media controls such as volume and screen brightness are executed with the function button strip on the keyboard, and are function-reversed, and you can simply press the volume key directly.

The glossy 16:9-ratio 12.5-inch screen on the ThinkPad Edge E220s has a pretty standard-for-laptops resolution of 1,366x768 pixels, which looks sharper on the slightly smaller screen than it does on a 13-inch laptop. Screen brightness is above average, although the viewing angles degenerate quickly when the screen is tilted too far. Then again, the Edge E220s's top lid only opens up about 135 degrees instead of the near-180 tilting on some ThinkPads. Basically, this means you'll likely be viewing the E220s' screen head-on most of the time, anyway.The stereo speakers situated in a grilled bar above the keyboard are enhanced with Dolby sound. This makes a difference when listening to movies and music: while it's not enthusiast-level, this is one of the best-sounding tiny ThinkPads we've encountered. Volume levels get loud, and we made do with just half-volume most of the time. Being a "premium" level ThinkPad Edge, the E220s not surprisingly comes with an HD Web cam that's better than you'd normally find on a 12-inch-class laptop. The maximum 1,280x720-pixel-resolution camera has good contrast and light sensitivity, and Lenovo's Web conferencing audio settings have pro features such as keyboard noise suppression.

Networking Ethernet, 802.11n Wi-Fi, Bluetooth, optional WiMax/mobile broadband Ethernet, 802.11n Wi-Fi, Bluetooth, optional mobile broadband The selection of ports on the ThinkPad Edge E220s is more than suitable for its size--in fact, it matches what you'd find on most 13-inch and larger laptops. Three USB 2.0 ports--one of which is an eSATA combo--are efficiently placed along the sides, along with VGA and HDMI. USB 3.0 isn't present, but most people don't even use it yet. Bluetooth (a $20 extra) and the presence of Intel Wireless Display (a feature on a great number of Intel-powered 2011 laptops that requires a sold-separately receiver box for your TV) offer additional connectivity options. A rear SIM card slot is easily accessible for 3G broadband-enabled configurations. WiMax is available as an option for an extra $55.Our configuration of the Edge E220s came with a Core i5-2537M CPU, 4GB of RAM, and a 320GB, 7200rpm hard drive, which currently costs $819 on Lenovo's Web site. The E220s starts at $749, with a Core i5 processor, 2GB of RAM, and a 250GB, 5400rpm hard drive. Windows 7 Professional costs an extra $50 to preinstall; upgrading from 2GB to 4GB of RAM costs $80; upgrading from a 250GB 5,400rpm hard drive to 320GB and 7,200rpm costs $70; or, a 128GB SSD option costs $350.

With a 14-inch screen, the Acer Aspire TimelineX 4820T seems like a good compromise between an ultra-portable and a desktop-replacement laptop. It's currently available for around £450 from Laptops Direct and other vendors, but is it the ideal laptop for busy souls who cart their computer around everywhere they go?Before we find out, note that the exact model number of our review sample is AS4820T-373G32Mnks or, alternatively, LX.PSN02.207.Measuring 342mm wide, the 4820T feels more portable than larger, 15-inch machines, yet also more comfortable to use than smaller, 13-inch ultra-portables. Weighing in at 2.2kg, it isn't the lightest laptop around, though.The 4820T's design isn't exactly mind-blowing, but the combination of the black brushed-metal effect on the lid and the sober grey that adorns the wrist rest makes for a machine that looks very business-like. The laptop's good build quality also inspires confidence that it should stand up to the knocks and scrapes of daily use.The 4820T's display has a glossy coating, but it isn't as reflective as some we've come across, so working under bright overhead lights isn't really a problem, as long as you position the screen correctly. The display's resolution of 1,366x768 pixels is pretty standard for a laptop in this price range, and the viewing angles on both the horizontal and vertical axes are pretty good. The screen could be brighter, though -- something that would also help colours to shine through more.

The keyboard uses flat keys perched on top of narrow stems, so they have the appearance of floating above the laptop's chassis. Acer has used a similar design to great effect on other keyboards, but this one flexes slightly, so it doesn't feel quite as solid and responsive to type on. Nevertheless, the wide trackpad is excellent and the long, narrow button beneath it is also top-notch. The HDMI port makes it easy to hook the laptop up to a hi-def TV. Ports aren't exactly abundant. For example, there's no eSATA port or PC Card slot. This isn't unusual at this price point, though, and you still get three USB ports, which you can use for connecting up peripherals like external hard drives.We also like the fact that the laptop includes an HDMI port alongside the VGA out. An HDMI port makes it much easier to connect the laptop to a high-definition TV, as both audio and video are carried across a single lead.

The machine supports both 802.11n Wi-Fi and Gigabit Ethernet, but not, sadly, Bluetooth. Most people probably won't be all that bothered about this, though. If you really want to add this functionality, you can now get tiny plug-in USB Bluetooth adaptors that sit almost flush with the chassis, for around £5 online. My MacBook Air has been down to about 2 hours of battery life and I finally looked into what the problem might be. At the same my friend who had the same issue took her MBA to the Apple Store and the guy there "fixed" hers. He didn't explain what he did but after some digging we figured out that he reset the System Management Controller.After doing a full backup I reset mine and now the machine says I have 3 hours 40 minutes of battery life available, though I do have wifi turned off, which seems to really eat up the charge.The System Management Controller is an integrated circuit (computer chip) that is on the logic board of the computer. As the name implies, it is responsible for power management of the computer. It controls backlighting, hard disk spin down, sleep and wake, some charging aspects, trackpad control, and some input/output as it relates to the computer sleeping.

Over time, the settings in the System Management Controller may become unusable, which can result in operational anomalies with the computer. Examples include not turning on, not waking from sleep, not charging the battery, or not recognizing the AC Adapter, among others. On another note I have seen this machine do some weird things with the memory usage. There have been several times when I quit all my apps and the MBA is still using 90% of the memory. We don't expect every new gadget to completely change the face of technology, but we do like to see at least some progress when we unwrap the latest parcel from the postman. Progress in the world of netbooks seems sluggish these days, so the Acer Aspire One 522 is very welcome. This 10.1-inch machine offers a better-than-usual screen, an HDMI port and a dual-core AMD processor -- all for £250 or thereabouts.The 522's design is very pleasant, if unremarkable. Except for a blue LED that surrounds the power switch, the netbook looks charmingly understated. It comes in either black or green. Our green version looked rather classy, thanks to the glossy finish on the lid and the metallic effect on the wrist rest.

The screen is surrounded by a glossy black plastic bezel, and the keyboard stretches right up to the edges of the chassis. We were impressed by how light this netbook is. Our model tipped the scales at a modest 1.2kg, including its three-cell lithium-ion battery. A version with a six-cell battery is also available, weighing 1.3kg.You won't have any trouble squeezing this netbook into a satchel, backpack or handbag, thanks to its slender dimensions. It measures 259 by 26 by 185mm. Peering at it from the side, the 522 indeed looks quite slim.A netbook lives and dies by its keyboard. After all, what's the point in buying a netbook if you're going to end up making so many typing mistakes that you'll feel like snapping it over your knee? Happily, the 522's keyboard is rather good. We didn't notice the keyboard wobbling as we rattled off sentences, and indeed the whole chassis feels reassuringly solid.There are a few issues, though. The enter and delete keys are really small, and that's bound to get irritating. There's also a small gap between each key, so you'll need to take care not to scatter crumbs over the keyboard, or they may vanish inside the 522 forever.
