Many times, we need to put our Windows computer into Sleep Mode, so that we can instantly wake and use it when we need it, without losing the time required for booting it. But sometimes, Windows will not Sleep. If Windows 11/10 refuses to sleep or won’t go into sleep mode, this post will show you how to fix the Sleep Mode not working problem.

You may experience one of the following scenarios:

PC wakes immediately after you put it to sleep.

Check if you have a sensitive mouse
Configure or Reset Power Plans to default
Rollback or Update drivers

If your mouse is sensitive, then a vibration could also wake up your PC. It would then be best to Off your mouse after you put your PC to Sleep.

Alternatively, you may open Device Manager > Expand Mice and other pointing devices > Right-click on the mouse > Properties > Power Management tab and uncheck Allow this device to wake the computer > Click OK.
