Dont Sleep is a lightweight program for Windows developed to block system sleep, shutdown, restart, hibernation or log-off actions.
Prevention
This small tool prevents PCs from entering sleep mode, hibernating, shutting down or restarting unexpectedly. Users can make sure that critical downloads, backups or data transfers are not interrupted by system power-saving actions. It is possible to override Windows 11 and lower power settings without requiring system-level changes.
There is a built-in timer that helps to stop blocking after a set duration or schedule activation during specific times of the day. The scheduler makes it easy to automate protection for routine overnight tasks or long render sessions. You can also toggle behavior based on CPU or battery activity.
Optional choices
There are options to block access to certain system functions like logoff or standby. You can also temporarily disable the power button or system idle actions. The settings are adjustable on-the-fly, giving you total control over how and when the computer behaves, especially useful in kiosks, presentations or unattended operations.
Features
- runs silently in the background with quick access;
- no setup is necessary, however the executable file itself is not safe to be installed;
- possible to adjust behavior according to overall charging or battery consumption;
- free to download and use;
- compatible with modern Windows versions.
