How to Keep Your Screen Awake

  1. Click "Start Keeping Awake"; the browser requests a screen wake lock from the system.
  2. Pick a duration: 30 minutes, 1 hour, 4 hours, or unlimited.
  3. Click "Stop" when finished; closing the tab also releases it immediately.

FAQ

Does the screen stay awake after closing the tab?
No. The wake lock is released automatically when the page closes; browsers never keep it in the background.
What happens if I switch tabs or minimize the window?
The browser temporarily releases the wake lock; it is re-acquired automatically when you return to this page — no extra click needed.
Why not just change the system power settings?
Nothing in your system configuration changes. Turn it on and off at will — ideal for presentations or borrowed devices. After stopping, the system sleeps as usual.
Does it consume extra power?
It only prevents the idle screen-off; screen power draw is unchanged and there is no background activity.
Which browsers are supported?
Chrome, Edge and other Chromium-based browsers plus Safari 17+ are supported. Firefox does not support it yet; the page will show a notice.
