Keep Awake Chrome extension

Keep Awake overrides your computer's power-saving settings so the screen doesn't dim or the system doesn't sleep while it's active. It's best for tasks like presentations, downloads, or long-running processes where you don't want an interruption. The catch: it's a simple toggle with no scheduling or per-site rules.

What Keep Awake does

Keep Awake overrides your operating system's power-saving settings so your screen doesn't dim or lock and your computer doesn't go to sleep while the extension is toggled on. This is useful for presentations, watching long content, or letting a download or process finish uninterrupted.

Is Keep Awake free?

Yes, Keep Awake is free to install and use from the Chrome Web Store. It has no listed paid tier; it functions as a single-purpose power-management toggle.

Is Keep Awake safe?

To override sleep and screen-dimming behavior, the extension needs system-level power permissions, which is inherent to what it does. It doesn't need access to your browsing content or history to function.

How to Keep a Chromebook Awake

Keep Awake: FAQs

Does the Keep Awake extension have a paid version?

No paid tier is listed. It is free on the Chrome Web Store and works as a single-purpose toggle.

What permission lets Keep Awake block my computer from sleeping?

It uses system-level power access so it can override sleep and screen dimming. It does not need your browsing content or history to do that.

How do I switch Keep Awake on and off?

Pin the icon, click it to start the override, and click it again when you no longer need it. There is nothing to configure first.

How much faster will my laptop battery drain with Keep Awake on?

There is no exact figure. Blocking sleep uses more power than normal, so plug in for long sessions and switch it off when the task is done.

Can Keep Awake shut itself off after a set time?

No. It is a manual toggle with no timer or schedule, so you have to click the icon to turn it off.

Keep Awake or my operating system's power settings: which is simpler?

Keep Awake is a one-click toggle that saves you digging through OS settings each time. Changing the OS setting is better if you want a permanent rule rather than a temporary override.

Does Keep Awake keep just the screen on, or the whole system?

It overrides system-level power-saving settings, which covers both screen dimming and system sleep.

Why does Keep Awake ask for system-level access?

Overriding sleep and power saving is a system function, so a normal page permission is not enough. That access is the core of what the extension does.

Do I need to sign in to use Keep Awake?

No. It works immediately after installation without sign-up.

Do I need to keep a Keep Awake window or popup open for it to work?

No. Once you click the toolbar icon to turn Keep Awake on, it keeps overriding your system's sleep settings in the background. You don't need any window open, and clicking the icon again turns it off.
