What Keep Awake does

How to keep your screen awake
Everything happens in the browser. Choose the option that fits how you are working when you want to keep your screen awake, keep your monitor awake, or prevent screen sleep for a set amount of time.

Frequently asked questions
Common questions about how to keep a screen awake, prevent screen sleep, and use a browser wake lock.
Can this keep my computer awake and prevent screen sleep?
It requests a screen wake lock through the browser to help keep the display awake. Exact behavior can vary by browser, operating system, device power settings, battery state, and page visibility.
Why use the mini pop-out to keep the monitor awake?
The small pop-out makes it easier to keep the wake lock window visible while using other applications or browser windows, which can be useful when you want to keep your monitor awake without leaving the full tool page in front.
What does “Pin on Top” do?
On supported browsers, Document Picture-in-Picture can keep the compact control above other windows. The normal pop-out remains available when that feature is unsupported.
Does this tool upload my files or screen contents?
No. The wake-lock function itself does not require your files, camera, microphone, or screen contents.
What happens if I close the page?
The wake lock owned by that page or pop-out ends, so it can no longer keep the display awake and your normal device power settings take over.
Why might the wake lock turn off by itself?
Browsers and operating systems can release a wake lock when visibility or power state changes. The mini window attempts to reacquire the lock when appropriate so the browser keep awake tool can continue helping prevent screen sleep.
