On top of that, use common sense when it comes to being wary of downloads and suspicious-looking email links. Again, keeping the number of unnecessary applications and browser extensions down to a minimum improves security, as it limits how many potential points of attack youâ€™re vulnerable to.You might not think that external dust and grime affects the inner workings of your laptop too much, but small bits of dirt and liquid can get between cracks and crevices and cause hardware problems down the line. The screen is another component you should keep clean to ensure as long a life as possible.

The very latest and slimmest laptops are fan-free, but irrespective of how many fans your computer has, anything that blocks air circulation can cause problems for your device. You should make sure thereâ€™s plenty of room around your laptop while youâ€™re using it.A lint-free cloth, isopropyl alcohol and distilled water are usually the tools recommended for the job (avoid tap water and standard household cleaning products), and a can of compressed air can come in very handy too for clearing blockages and blasting detritus away from the keyboard and your laptopâ€™s ports.

The more ambitious among you might want to open up the laptop casing for an even deeper clean, but proceed at your own risk and make sure you know what youâ€™re doingâ€”there are plenty of thorough cleaning guides around on the web that you can follow.The MacBook is getting an update, Apple announced on Tuesday. Here's what you need to know:

The biggest changes to the 2016 MacBook are that it includes a new Intel processor, and it now comes in a "rose gold" color.
The laptop starts at $1,299 for a configuration with a 2.2 GHz chip and 256 GB of storage. You can also opt for a higher-end model with a faster chip and 512 GB of storage for $1599.
The MacBook is Apple's thinnest laptop â€” less powerful than the MacBook Pro, but thinner, lighter, and more expensive than the MacBook Air.
Apple's MacBook only comes with one port: A single USB-C port that is used not only for charging the notebook, but also for data transfer or adding a second monitor.
The new MacBook will use a "sixth-generation" Intel Core M processor, which can deliver "turbo boost" speeds up to 3.1 GHz. The chips that Apple is using will also sport improved graphics performance.
Most importantly, the new chips will enable the 2016 MacBook to squeeze out 10 hours of wireless web-browsing time, or 11 hours of movie playback.
You can buy the 2016 MacBook on Apple.com on Tuesday, and it will hit retail stores on Wednesday.
The superslim 12-inch MacBook is beefing up on the inside. Apple is updating its thinnest and lightest laptop with a 6th generation Core M processor, faster flash storage and an additional hour of battery life. The company is also adding a rose gold color option. The price remains at a premium $1,299, and you still get only a single USB-C port.

The base model features a 1.1-GHz Core m3 CPU, 8GB of memory and 256GB of faster flash storage, while $1,599 gets you a Core m5 chip with the same RAM but a larger 512GB of flash storage.Apple says the new Intel HD graphics 515 offers up to 25 percent more graphics performance, while the PCIe-based flash storage speeds up tasks like opening files and launching apps.The most welcome upgrade is the 10 claimed hours of battery life. In our review of the previous 12-inch MacBook, Apple's ultraportable lasted 8 hours and 43 minutes, or a little less than the 9-hour claim.

What Apple hasn't changed is the port selection. You still get a lone USB-C connector, which means if you want to plug in a power cable and connect another device at the same time, such as your iPhone, an external display or a peripheral, you're going to need a dongle or USB-C docking station.
The MacBook continues to offer a Force Touch trackpad, which uses feedback to simulate a physical click, and a rich 2304 x 1440 display that puts the MacBook Air to shame. (At least Apple has decided to make 8GB of RAM on the Air line standard as of today.)

For better or for worse, the MacBook is the ultimate laptop for minimalists, but now it has maximum power and endurance. Let us know in the comments if you would buy one for yourself.

Chromebooks -- notebooks that run Google's Chrome OS -- get a bad rap because many look cheap, feel disposable and lack speed. The Acer Chromebook 14 has none of these problems, as its brushed metal lid and aluminum chassis give it a sleek design and great build quality. The 14-inch notebook's strengths aren't shell-deep, as it packs enough punch for productive multitasking. The notebook is only held back by its uncomfortable keyboard and dull display. While the Acer Chromebook 14 isn't the best of its breed, it's still worth consideration.
Weighing 3.42 pounds and measuring 0.67 inches thick, the Acer Chromebook 14 is a bit thinner and about as heavy as the HP Chromebook 14 (3.48 pounds). The Dell Chromebook 13 (3.23 pounds) and Toshiba Chromebook 2 CB35 (2.97 pounds) are understandably lighter because they have smaller screens. While carrying the Acer in my backpack on my commute, it didn't add too much heft or take up a ton of space.
The Acer Chromebook 14's 0.9-megapixel webcam shot pixelated photos of me in our office that appeared to have been set in a pointillist filter. While the camera did a good job of reproducing the red of the wall behind me, it captured little to no detail, with most of my hair registering as a brown swoosh.

Display
The Acer Chromebook 14's display has a sharp resolution of 1920 x 1080 pixels, but it's on the dull side. When I streamed the 1080p trailer for Captain America: Civil War on the screen, Captain America's helmet looked more black than blue and Spider-Man's red costume didn't pop. However, I appreciated that the cloud of smoke around Bucky rendered without pixelation, a problem I've seen on a lot of screens that aren't as sharp.
According to our colorimeter, the Acer Chromebook 14's display can produce only 62 percent of the sRGB spectrum. That's lower than the HP Chromebook 14 (65 percent), Dell Chromebook 13 (96 percent), Toshiba Chromebook 2 CB35 (110 percent) and the average thin-and-light notebook (82 percent).

The Acer Chromebook 14 is relatively good at displaying accurate color, as it earned a score of 0.99 on our Delta-E test (zero is perfect). That beats the Dell Chromebook 13 (1.4) and the category average (2.4), but the HP Chromebook 14 (0.5) and Toshiba Chromebook 2 CB35 (0.9) earned better marks.
The Acer Chromebook's panel emits up to 215 nits (a measure of brightness), which is near the HP Chromebook 14 (212 nits), but dimmer than the Dell Chromebook 13 (270 nits), Toshiba Chromebook 2 CB35 (378 nits) and the category average (251 nits). Don't expect wide viewing angles, as I saw color darken significantly at 45 degrees.

If you need your laptop to double as a stereo, the Acer Chromebook 14 blasts plenty of volume, with no distortion. The notebook filled a large conference room with an excellent reproduction of James Blake's "Timeless," rendering clear guitar strings, strong bass and the sweet high notes of the track's synths.

Keyboard and Touchpad
Typing on the Acer Chromebook 14 felt like drumming my fingers against my wooden desk. Acer gave the notebook keys with only 1.14 millimeters of travel, which is too shallow and leads to bottoming out (the act of slamming one's digits against the deck). We prefer keyboards with between 1.5 and 2 mm of travel. When I tried the Acer Chromebook 14 out on the 10fastfingers.com typing test, these shallow keys limited me to 72 words per minute, a dip from my 80 wpm average.
The Acer Chromebook 14's 4.1 x 3-inch, buttonless touchpad accurately tracked my input as my fingers navigated around the desktop, and there was a solid feel to each click. The notebook smoothly responded to my two-finger scrolling, and it correctly registered my three-finger navigational swipes.
Acer gave the Chromebook 14 a 1.6-GHz Intel Celeron N3160 CPU, 4GB of RAM and a 32GB eMMC drive, which provide enough pep for multitasking. When I split my screen between a dozen tabs and a streaming 1080p YouTube video and opened Google Keep and Cut The Rope, the system stayed speedy. I saw no lag as I typed in a Google Doc, moved from tab to tab and switched between apps.

The Acer Chromebook 14 did OK on Google's Octane 2.0 performance test, which gave it a score of 7,840. The Celeron N2940-powered HP Chromebook 14 notched a comparable 7,869. However, the e Celeron 3205U-powered Dell Chromebook 13 (14,453) and Celeron 3215U-powered Toshiba Chromebook 2 (17,044) earned better scores.The Acer Chromebook 14 fared worse on the Browsermark test for overall performance, hitting 2,273. That's a lower score than what the HP (2,300), Dell (4,199) and the Toshiba (4,576) received.Acer's Chromebook 14 earned a score of 46.95 on the JetStream 1.1 test, which measures JavaScript performance. That beats the HP Chromebook 14 (46.1), but it's lower than what the Dell (86.3) and the Toshiba (99.2) notched.

Graphics
I had no trouble playing casual games like Cut The Rope and streaming 1080p video from YouTube on the Acer Chromebook 14, but again, synthetic tests favor its competitors. This system earned a score of only 4,080 on the Oort Online test, which measures the browser's ability to display CGI environments. That's below the Dell Chromebook 13 (5,050) and the Toshiba Chromebook 2 (5,060) earned, but better than the HP Chromebook 14 (1,480).

The Acer Chromebook 14 demonstrated acceptable performance on the WebGL Aquarium graphics simulation, which tests 3D rendering. The notebook mustered 47 frames per second with 250 and 500 fish in the tank, while the Dell and Toshiba both sped along at 60 fps with as many as 1,000 fish.

Heat
The Acer Chromebook 14 is one cool customer. After the laptop streamed 15 minutes of full-screen, HD video, our heat gun registered comfortable temperatures on its touchpad (74.5 degrees Fahrenheit), keyboard (78.5 degrees) and underside (80 degrees). All were less than our 95-degree comfort threshold.

Battery Life
You can leave your charging cable at home when you take the Acer Chromebook 14 to school or work. The notebook lasted 9 hours and 25 minutes on the Laptop Mag battery test, which is longer than the average thin-and-light notebook (7:56) and the HP Chromebook 14 (6:42). The Dell Chromebook 13 (13:25) and Toshiba Chromebook 2 CB35 (10:05) make it even longer on a single charge.
The Acer Chromebook 14 includes a one-year limited hardware warranty. Check out our Tech Support Showdown and Best and Worst Brands report to see how Acer fared.
