Dell Precision M60 Battery

You could also stick some malware on the microprocessor that would infect the computer time and time again. "You could put a whole hard drive in, reinstall the software, flash the BIOS, and every time it would reattack and screw you over. There would be no way to eradicate or detect it other than removing the battery."Miller also reckons it might be possible to remotely explode a laptop battery, though he hasn't tried that personally. "I work out of my home, so I wasn't super inclined to cause an explosion there," he said.What a cowaReasonable enough. Miller will be demonstrating how to hack a battery microprocessor at the Black Hat conference in Las Vegas next month, and he'll also be releasing a tool for MacBook users called 'Caulkgun' that will change battery firmware codes to something more complex than the default password, protecting them from attack.What are your thoughts? Let your fingers do the typey-talking in the comments section below, or on our Facebook page.Battery life is our most precious resource when we're out with a laptop all day without a powerpoint to save us. If you know it's going to be a long time between drinks for your laptop, the number-one thing that you can do to get minutes and even hours further in your day is to turn down the screen brightness!

When you're just typing up some notes or doing some basic work on the web, you hardly need the screen on at all. If you make a habit of giving yourself only just as much brightness as you need, you'll soon be achieving those 6+ hours of battery life that the laptop company promised you on the box.Remember Netbooks and ultraportable laptops? Those 10- and 11-inchers were all the rage a few years ago, but thanks to the rise of larger-screened ultrabooks and smaller-screened tablets, they've been disappearing from the computer landscape.One significant 11-incher still remains: the 11-inch MacBook Air. When it first debuted in late 2010, it was the answer to the Netbook Generation. Now it stands alone, not only as a speedy ultraportable, but as one of the few 11-inch ultrabook-class laptops around. The closest Windows equivalent we've reviewed recently, the Dell XPS 13, is larger and heavier. Last year's 11-inch Air was a beautifully compact and surprisingly powerful machine, nearly as quick as a 13-inch Air, but with sacrificed battery life due to its tiny size.

This year's model is faster, packing a third-gen Intel Core i5 processor that's nearly indistinguishable from the one in the larger 13-inch MacBook Air. USB 3.0 ports have been added, and battery life is better, finally clearing 5 hours and then some on our tests. The other problem had to do with price: last year's attractive $999 entry-level MacBook Air came with a diminutive 64GB solid-state drive (SSD) and only 2GB of RAM (which couldn't be upgraded). The package you really had to upgrade to was the one with a 128GB SSD and 4GB of RAM, which cost $1,199.This year, the entry-level 2012 11-inch Air is still $999 -- the least expensive MacBook in Apple's lineup -- but still only has a 64GB SSD (though 4GB of RAM this time). The good news is that the configuration you'll want, with a 128GB SSD, costs $1,099, $100 less than last year's step-up. (If I were to be really nitpicky, I'd say that that $100 bump-up only buys you more SSD space as opposed to last year getting the SSD and RAM, but the total cost for components is $100 less either way). A thousand dollars is a lot to pay for such a tiny laptop, but this Air's shocking portability and comfortable keyboard will win travelers over, with performance that's pretty much as good as that of the fuller Air. You're giving up about 2 hours of battery life and an SD card slot for the privilege compared with the 13-inch. Then again, some might enjoy saving an extra $100 off a similar 13-inch configuration. Either way, the 11-inch seems better as a luxurious secondary computer than a primary one.

Unlike Microsoft and its Windows 8 strategy, Apple has pursued two nonoverlapping paths for mobile computing in the iPad and the MacBook Air. The Air is a full OS X laptop, but it feels iPad-size when closed. Its dimensions, while longer and thicker, aren't far off. From the front, the 0.11-inch edge looks iPad-thin; it's 0.68 inch thin on the back. At 2.38 pounds, it's a little under a pound heavier than the third-generation Retina Display iPad.The new 11-inch Air is identical to last year's in size, shape, and design, and hasn't changed at all since its introduction in late 2010. It still looks cutting-edge; the all-metal aluminum construction gives it a seriously solid feel despite its blade-thin profile, and the whole package feels thin and light even to someone used to working with very small laptops (such as myself). Yet, even though the Air is small, it manages to avoid compromising the keyboard and trackpad -- they're full-size -- or even screen resolution, which is a standard 1,366x768 pixels. You can see upon lifting the Air's lid that the 11.6-inch screen has a significant aluminum bezel around it, enough space, it feels like, for a 12-inch screen. The reason for the extra bezel is clear when you look below: the large, wide keyboard is basically identical in size to the 13-inch Air's, fitted snugly edge to edge. The Dell XPS 13, a 13-inch ultrabook shrunk into a 12-inch footprint, is still larger and heavier at 3 pounds versus the 11-inch Air's 2.38, and thicker all around.

The backlit keyboard has the same shallower raised keys as the 13-inch Air, but the typing experience, once you get used to it, feels excellent. The multitouch glass clickpad below is still the best in its class, perfectly responsive and tuned to Apple's operating system and software. The pad's surface area is smaller than on a 13-inch Pro or Air, but there's plenty of room for basic navigation -- although four-finger pinch gestures can get a bit cramped.The only cosmetic change to the Air's exterior is a new MagSafe 2 connector that fits with a new charging cable that juts out rather than riding snugly along the Air's side. The connector port isn't compatible with older MagSafe cables.Episode 37of the Digital City, where we discuss the new Apple iPhone 3Gs and the Palm Pre; the best of E3, according to Nielson; a record legal judgment against online music sharing; and why you can't trust anyone's laptop battery life tests, except ours.You'll notice that we're also part of the new CNET Live slate of programs, and you can catch the Digital City every Friday at 3pm EST at cnet.com/live, or just catch up on it later right here on our blog.

Watch or listen to the show for details on how to enter...]The top spot is a bit of a surprise, going to the Acer Chromebook R13, a budget-friendly but long-lasting Chrome OS laptop. The top Windows system is Microsoft's 2016 refresh of the Surface Book, which benefits from having a battery in its tablet screen and a second battery in its keyboard base.Apple's MacBooks are typically thought of as having excellent battery life, though the 2016 Pro models sometimes require an extra bit of coaxing to overcome uneven battery performance. The highest-ranking MacBook right now is the version of the 13-inch MacBook Pro without Apple's new Touchbar, at no. 3. (The 2015 MacBook Air lasts even longer, but it's an aging model with a lower resolution screen.)Microsoft's Surface tablet PCs have come a long way since their 2012 launch, but the concept behind the design remains unchanged: A tablet that can convincingly double as a laptop.

Both the hardware and the Windows OS had to mature, and it finally hit its stride with 2015's Surface Pro 4. It instantly became the ideal that other PC makers should follow -- and they did, as Lenovo, Samsung, Acer and others released their own versions of Microsoft's 2-in-1 device.Like the Surface, these 2-in-1s are Windows 10 tablet PCs with detachable keyboards, giving you a more laptop-like experience, whereas hybrids like Lenovo's Yoga 910 or Dell's XPS 13 2-in-1 are laptops that have screens that fold back 360 degrees so they can be used as a tablet. Tablet PCs typically have fewer ports than their laptop counterparts and don't last as long on battery power, but they're also slimmer, lighter and have active pen support, giving you a more natural feel than you'd get from a passive stylus.While we're expecting the Surface Pro 5's arrival this spring, there are several alternatives worth checking out right now. And since many were released after the Surface Pro 4, you'll find updated features like USB-C ports and active pens with greater levels of pressure sensitivity.

The Miix comes very close to the Surface Pro 4 in performance, battery life and features, but it costs much less. They nearly look identical, too, and Lenovo includes its keyboard (though its Active Pen isn't). It's got a 12.2-inch 1,920x1,200-pixel display compared to the Pro 4's 12.3-inch 2,736x1,824-pixel resolution display, and it lacks a microSD card slot, but the Miix does have a USB-C port instead of Microsoft's proprietary Connect connector. Pricing starts at $600.It's pricey, but for digital artists Wacom's MobileStudio Pro is the ultimate mobile solution. The tablet has an exceptionally good feel and 8,192 levels of pressure sensitivity with its new Pro Pen 2. Connect any Bluetooth keyboard to it and use it as a Windows 10 laptop, or like the Cintiq line from which it evolved, you can connect it to another computer -- Windows or Mac -- and use it as an interactive pen display and graphics tablet. Pricing starts at $2,000.The Switch's design, keyboard and performance are impressive and it runs quiet, thanks to a fanless design (something the Lenovo Miix can't match). And while its screen resolution was lower than the Surface Pro 4's 4K display, it was still nice to use. The only disappointment was its optional pen, so unless that's crucial, you might want to investigate this Acer a little more. Pricing starts at $700.

The TabPro S is thinner than others here, making it feel more like an iPad. It also has great battery life at more than 7 hours, and a brilliant AMOLED display that makes using it a pleasure. What's a little less pleasurable is its slightly underpowered Intel Core M processor. Also, the bundled keyboard cover's keys are a set too close together for comfortable typing. Plus, without a built-in kickstand, you're limited to the two positions the cover provides. The overall value here is excellent, though. Pricing starts at $700.Aimed at business users, the X1 lacks the more stylish design of Lenovo's Miix hybrid, but it gains something else entirely: modularity. A proprietary port for the keyboard attachment can also connect to add-on modules to increase your ports and battery life, add a small projector, or attach an Intel RealSense camera for depth sensing and 3D scans. Pricing starts around $1,000.Like Samsung's TabPro S, the Matebook is designed more like an iPad than other Windows 10 tablets. It has an excellent screen and nice-sounding speakers (for a tablet, at least) and a responsive fingerprint sensor that made logging into Windows a snap. Unfortunately, the keyboard and pen aren't included, so unless you can find it at a significantly better price than the Samsung, you might just as well get that instead of the Matebook. Pricing starts at $500.
