If you've chosen a Chromebook as a laptop, then you know the main benefits that it brings: namely, speed, ease of use, and affordability. Despite the simplicity of ChromeOS, however, there's more that you can do with it than you might realize. You can use it offline, and you can sync files to and from local storage, for example. The operating system is a lot more powerful and versatile than it often gets credit for.These hacks are for power users who want to level up their Chromebook capabilities, and get extra value out of their laptop, beyond the standard use cases that everyone knows about. No matter how you use ChromeOS, there should be something here to help.Use your Chromebook offline Google Drive can work offline. Credit: Lifehacker Chromebooks are often criticized for being useless without wifi, but that's not actually the case: All of the Docs, Sheets, and Slides tools can be used offline, with changes syncing back when your internet connection is restored: From Google Drive, click the gear icon (top right), then choose Settings > General and check the option under the Offline heading.You can use Gmail offline, too. You can't send or receive emails, obviously, but you can read through and organize your inbox, and draft emails ready to go once you get your internet back. From Gmail, click on the gear icon (top right), then pick See all settings > Offline. Check the Enable offline mail box and choose how much of your email you want to sync.Sync media offlineThis offline functionality extends to third-party streaming apps too, as ChromeOS supports Android apps. With apps such as Netflix and Spotify, you can sync content to your Chromebook to watch when you don't have a reliable internet connection—when you're on a long flight, for example, or traveling between countries.Talk to your Chromebook Enable dictation through the Accessibility settings. Credit: Lifehacker Typing is all well and good, but sometimes talking is faster. Launch Settings, then choose Accessibility > Keyboard and text input > Dictation to enable the feature. You can then press the Launcher (G) button and D to start dictating in any app—whether you're composing emails or writing essays.Move local files to Google DriveOne of the pros of using a Chromebook is that everything is synced online pretty much instantly, if you're using one of Google's own online apps or something similar. However, there may be local files that accumulate on the laptop, including screenshots and downloads, and sometimes you'll want to get those synced to the cloud as well.You can see these files via the Files app that comes built into ChromeOS, and upload them manually via the Google Drive web interface. There's an easier way to get them into Google Drive, though: From the Files app, select all the local files you want to upload in the pane on the right, then drag them into My Drive under Google Drive in the left-hand menu bar.Set up virtual desktopsChromebooks don't always have the biggest or highest-resolution screens, but you can give yourself more room by managing multiple virtual desktops (which ChromeOS calls "desks"). Press the "show windows" key (it's the one with little rectangles on it, usually also labeled F3) to view open desks, switch between them, and create new ones.Enable guest accessAs ChromeOS is so tightly tied to your Google account, you don't necessarily want other people borrowing your laptop and being able to get into your Google apps. The solution is guest mode: Restart your Chromebook or sign out of your current user account, then click Browse as Guest to launch a Chrome window without any Google account attached.Make full use of the clipboardChromeOS can sometimes feel limiting in that you can't quickly drag files to the desktop or to a temporary folder in the same way that you can on Windows or macOS. You might also see that as a benefit—it means less junk will be cluttering your system—but there could well be times that you just need to store something temporarily for transfer.That's where the ChromeOS clipboard comes in: It actually stores five items rather than one, so it's a useful (if rather hidden) way of moving images, text, and links between websites and apps. Use the usual Ctrl+C, Ctrl+X, and Ctrl+V shortcuts to copy, cut, and paste, then hold down the Launcher (G) button and V to see all the clipboard items.Open the ChromeOS Task Manager ChromeOS comes with its own Task Manager. Credit: Lifehacker The ChromeOS Task Manager is useful for everything from shutting down crashed apps to seeing exactly where all your RAM is going, and it can be a key tool in the power user's belt. Open it by pressing the Launcher (G) key and Esc: You'll see you can browse between individual tabs and system processes, or search for something specific on ChromeOS.Save an older laptopChromeOS isn't just for Chromebooks: You can give an older, struggling laptop a new lease of life by installing ChromeOS Flex on it (even old laptops can usually handle Chrome). Google has full instructions for what you need to do to get this working, and will guide you through the process of creating a bootable USB drive with the ChromeOS software on.Explore beta and dev channels Switching up the channel on ChromeOS. Credit: Lifehacker As with a lot of software, there are beta and dev channels of ChromeOS available as well as the stable one. If you want to get the newest Chromebook features before everyone else, and don't mind a few bugs along the way, then you can make the switch. It doesn't take long, and you can always switch back again, though a system reset is sometimes required.To change between ChromeOS channels, click on the time panel (bottom right), then click the gear icon to get to the main Settings page. Choose About ChromeOS > Additional details > Change channel, then choose whichever one you want to use. You'll keep getting over-the-air updates for your selected channel until you switch to a different one.
