Windows's own options, and when to use this instead
Windows has its own sleep/lock timing under Settings → System → Power & sleep, and Microsoft ships a dedicated tool for this exact problem: PowerToys Awake, which can keep the machine (and optionally the display) on indefinitely or for a set time, from a system tray icon.
If you can install software and have admin rights, PowerToys Awake is a solid, more persistent option — it keeps working even if you close the browser. This tool exists for the opposite situation: a locked-down work laptop where you can't install anything, or you just don't want to touch system settings for a one-off task. Open the tab, click start, close it when you're done — nothing to undo afterward.
Chrome and Edge both support the underlying Screen Wake Lock API natively on Windows, so this works the same in either browser with no extension required.
FAQ
- Does this change my Windows power plan?
- No — it doesn't touch any Windows setting. It only holds a signal while this tab is open, and releases it the moment you close the tab or stop it.
- Will it work if I lock the screen manually (Win+L)?
- No — a manual lock always wins, as it should. This only prevents the automatic idle-timeout lock, never a deliberate lock.
