How to Keep a Chromebook Awake

How do I stop my Chromebook from sleeping without an extension?

ChromeOS has its own sleep timers built into Settings, and adjusting them is the first thing to try before adding an extension — no install required.

1. Click the status area in the bottom right and select the gear icon to open Settings.
2. Choose Device in the left sidebar.
3. Select Power.
4. Set When idle to Keep display on if your ChromeOS version offers it, or extend the sleep timer to its maximum.
5. If your Chromebook is plugged in, some versions add a separate Keep display on while charging toggle — turn that on too.

These idle timers exist by default to save battery and reduce wear, so a longer setting trades some of that back for convenience. Menu names shift a little between ChromeOS versions, so if a toggle above isn't where this describes, check your About ChromeOS page for your version and search Settings directly instead.

Why use a keep-awake extension if Settings already has this option?

A Settings change is permanent until you undo it; a keep-awake extension is a toggle you flip on for one task and off again, which matters if you only need the screen awake occasionally.

It's also the faster option on a managed school or work Chromebook, where an admin policy may lock the Power settings page entirely. An extension that requests the right permission can sometimes still work in that situation, since it's a per-user toggle rather than a device policy change — though a strict admin policy can block extensions too, so it's not guaranteed.

The other reason: a dedicated keep-awake extension usually adds a visible on/off icon in the toolbar, so you can see at a glance whether it's currently keeping your screen on, instead of having to reopen Settings to check. For a presentation or a video call where you can't risk the screen dimming, that visible confirmation matters.

How to install and use a keep-awake extension on Chromebook

Keep Awake and Stay Awake both work the same basic way: install, click the icon, and your screen stays on until you turn it back off.

1. Open the Chrome Web Store and install Keep Awake or Stay Awake.
2. Pin the extension icon to your toolbar for quick access.
3. Click the icon once to turn it on; the icon usually changes to show it's active.
4. Leave it running for as long as you need the screen or system to stay awake — a presentation, a long download, a video call.
5. Click the icon again to turn it off once you're done, so your Chromebook goes back to sleeping normally on its own timer.

There's no configuration beyond that toggle for most of these extensions — they're built to be a single button, not a settings page, which is the appeal over digging through ChromeOS Settings every time you need it.

Keeping the display awake vs. keeping the whole system awake

Keep Awake (Display | System) splits the two behaviors that other keep-awake tools bundle together, which matters more than it sounds.

Keeping the display awake stops the screen from dimming and turning off, but the Chromebook can still let background processes idle down. Keeping the system awake goes further and prevents the whole machine from suspending, which matters for tasks that need to keep running with the lid open but the screen dimmed, like a long file transfer or a background sync you don't want interrupted.

If you only care about the screen staying visible, for a presentation, say, the display-only mode uses less battery than forcing the full system to stay active the entire time.

Keeping a school or work Chromebook awake

Managed Chromebooks often have Power settings restricted or hidden by an admin policy, which is the most common reason people search for a keep-awake extension instead of just changing a setting.

Whether an extension works depends entirely on your organization's policy: some admins allow any extension from the Chrome Web Store, others allow-list a specific set, and some block installing new extensions altogether. If installation fails, that block is coming from the device policy, not the extension itself — check with your IT or classroom admin, since the fix is on their end, not yours.

For students specifically, keeping a Chromebook awake mid-presentation or during a timed assignment is the usual reason this comes up; check your school's acceptable-use policy first, since some restrict keep-awake tools for testing scenarios on purpose.

If you're just trying to keep a video playing, you may not need an extension

Chrome already prevents your screen from sleeping while a video is actively playing in a tab, so a keep-awake extension usually isn't necessary just to finish watching something.

Where it does help is switching away from that tab: once you leave the video's tab, some setups treat it as no longer active and let the screen sleep anyway. Picture-in-Picture and YouTube PiP solve that differently — they pop the video into a small floating window that keeps playing while you work in other tabs, which keeps the screen awake as a side effect without needing a dedicated keep-awake toggle at all.

Whichever you pick, none of these need broad permissions beyond controlling power state — a good sign when choosing a keep-awake extension is that it doesn't ask for access to your browsing data at all.

Troubleshooting: the extension isn't keeping my Chromebook awake

Screen still sleeps with the extension on

Confirm the toolbar icon shows it's actually active — some of these extensions reset to off after a browser restart, so a reboot can silently disable it.

Chromebook sleeps as soon as I close the lid

That's hardware-level lid-close behavior; no extension can override it, since it happens below the browser.

Extension won't install

On a managed Chromebook, this usually means your organization's device policy blocks new extension installs — contact your admin rather than retrying.

Battery drains faster with it on

Forcing the display or system to stay awake uses more power than letting ChromeOS sleep normally; turn the extension off when you don't need it instead of leaving it running by default.

Does forcing your Chromebook to stay awake hurt the battery?

Yes, noticeably, if you leave it on all the time — the screen and system are two of the biggest battery draws on any laptop, and a keep-awake extension exists specifically to stop the power-saving behavior that protects your battery.

The practical fix is treating it like a light switch: turn it on for the specific task that needs it, a presentation, a long render, a video call where the screen dimming mid-sentence would be a problem, and turn it back off immediately after, rather than leaving it running as a permanent default.

Display-only modes, see Keep Awake (Display | System) above, cost less battery than full-system awake modes, so pick the lighter option when a task only needs the screen visible, not the whole machine staying fully active.

Keep-awake extensions on Chromebook vs. Windows and Mac

The same keep-awake extensions generally work on any device running desktop Chrome, but the native alternative differs by platform.
