Keep your screen awake online
The fastest way to keep a screen awake is the browser tab you already have open. No settings, no installs — one tap and the display stays on until you say otherwise.
Screen can sleep
0:00
Ready when you are
Keep this tab visible — browsers pause wake locks on hidden or minimized tabs.
Why use a website instead of a setting?
Changing your operating system's sleep settings is the right call for a permanent change. But plenty of situations call for something quicker and fully reversible:
- Managed work laptops. Many companies lock power settings behind IT policies. A browser wake lock needs no admin rights and changes nothing on the machine.
- One-off moments. A presentation, a long download, a recipe — set a timer for exactly as long as you need, and everything goes back to normal automatically.
- Shared or borrowed computers. Keep the screen awake without leaving changed settings behind for the next person.
What it can and can't do
| It can | It can't |
|---|---|
| Stop the display timing out and dimming | Keep running with the laptop lid closed |
| Hold the screen while this tab is visible | Work from a hidden or minimized tab |
| Auto-release after a timer you set | Override Sleep from the OS menu or power button |
| Work with zero install or admin rights | Guarantee anything on battery-saver or near-empty battery |
Working within the rules
The one rule that matters: browsers only allow a wake lock while the page is visible. Keep this tab open where you can see it — a narrow window beside your other work is ideal. Hide it, and the lock pauses; return, and it resumes by itself.
Tips for long sessions
- Plug in. An always-on screen uses power by design; long sessions belong on the charger.
- Use a timer as a safety net. Pick 1 hour — or a custom duration — so the lock releases even if you forget.
- Prefer the OS setting for “always” changes. If your screen should never sleep, our prevent screen sleep guide shows the permanent option for your device.
