About Keep Screen Awake
This page stops your screen from dimming and your laptop from going to sleep while it is open. It uses the Screen Wake Lock API, the same standard browsers use to keep a recipe or a slide deck on screen, so there is nothing to install and no system setting to change.
Pick how long you need, from 15 minutes to 8 hours, a custom number of minutes, or until you stop it. A countdown runs on the page and in the tab title, a short chime plays when time is up, and the lock is released so your power settings take over again.
While you wait, a quote changes on the screen every few seconds. There are more than a hundred, from Seneca and Marie Curie to Kartini and Linus Torvalds. Switch to focus mode to fill the screen with a big clock and the current quote.
How to use Keep Screen Awake
- Choose a duration, type a custom number of minutes, or pick Until I stop it.
- Click Keep screen awake. The status turns green while the screen is held on.
- Leave this tab visible. Open focus mode if you want a full-screen clock with quotes.
- Click Stop at any time, or let the timer finish and your normal sleep settings return.
No install, no admin rights
Works on work laptops where you can't install caffeine apps or change power settings. Everything runs in the browser tab.
Timer with a chime
Presets from 15 minutes to 8 hours, any custom length up to 24 hours, or open ended. The countdown also shows in the tab title.
Over 100 quotes
Carefully attributed quotes rotate every 10, 30 or 60 seconds, in Indonesian on the Indonesian site and English elsewhere.
Releases cleanly
When the timer ends, you click Stop or close the tab, the lock is gone at once and your usual screen and sleep timeouts apply.
How keeping the screen awake works
Operating systems dim the display and then sleep after a period without keyboard or mouse input. That is fine for battery life, but it gets in the way when you are watching a long download, reading a document hands free, presenting, following a recipe or monitoring a dashboard. The usual fix is a utility such as Caffeine or Amphetamine, or a change in power settings, both of which may be blocked on a managed work laptop.
Modern browsers expose a safer middle ground called the Screen Wake Lock API. A page asks for a screen lock, and as long as that page is visible the device will not dim or sleep because of inactivity. The browser decides the rules: the lock is dropped when you switch tabs, minimize the window or lock the computer, and it can be refused when the battery is low. This tool takes the lock again automatically when you come back to the tab.
A wake lock only prevents sleep caused by inactivity. Closing the lid, pressing the power button or a forced sleep when the battery is critical still win, which is exactly what you want from a tool that runs without special permissions. Some laptops also go to sleep on lid close even when connected to an external monitor, depending on the operating system settings.
Tips for better results
- Plug in your charger for long sessions. Battery saver modes can refuse or cancel a wake lock.
- Put this tab in its own browser window if you need to keep working in other tabs.
- Use focus mode on a second monitor as a clean clock with quotes during work or study sessions.
- If the status shows paused, click back into this tab and the lock resumes on its own.
Questions and answers
Will this stop my laptop from going to sleep?
Yes, as long as this tab stays open and visible. It blocks the screen dimming and the idle sleep that follow a period without input. Closing the lid or pressing the power button still puts the laptop to sleep.
Does it work if I switch to another tab?
No. Browsers release the wake lock when the page is hidden. Keep this tab visible, for example in its own window, and the lock is taken again automatically when you return.
Which browsers are supported?
Recent versions of Chrome, Edge, Opera, Safari 16.4 or newer and Firefox 126 or newer, on desktop and mobile. If your browser is too old, the page tells you.
Does it move my mouse or press keys?
No. It does not simulate input. It uses the official wake lock feature of the browser, so nothing is clicked or typed on your behalf.
Is anything installed or sent to a server?
No. The timer, the quotes and the lock all run in your browser. Closing the tab ends everything.
