Sleep mode saves your open work in memory and puts the PC into a low-power state, so it wakes up in seconds exactly where you left off. If Sleep is missing from the Power menu, or your PC never sleeps on its own, Windows 10 has a few settings to check. This guide covers adding Sleep to the Power menu, setting automatic sleep, power button and lid actions, and fixes when sleep isn’t available.
Quick Answer
To put the PC to sleep, click Start > Power > Sleep. If Sleep is missing, open Control Panel > Power Options > Choose what the power buttons do, click Change settings that are currently unavailable, check Sleep, and click Save changes. Set automatic sleep in Settings > System > Power & sleep.
Put Your PC to Sleep
- Start menu: click Start > Power > Sleep.
- Keyboard: press Windows + X, then U, then S.
- Laptops: close the lid (if set to Sleep), or press the power button (if set to Sleep).
Add Sleep to the Power Menu

Set Power Button and Lid Actions
In the same Choose what the power buttons do page, set When I press the power button and When I close the lid to Sleep for battery and plugged-in modes.
Sleep Option Missing or Not Working?
- Check available sleep states: in Command Prompt, run powercfg /a. It lists which sleep states your PC supports and why others aren’t available.
- Update the graphics driver: a basic display driver (after a fresh install) often disables sleep. Install your GPU or PC maker’s driver.
- Something keeps the PC awake: run powercfg /requests as administrator to see which app or device is blocking sleep.
- PC wakes up by itself: run powercfg /lastwake, and in Device Manager, uncheck Allow this device to wake the computer for the mouse or network adapter if needed.
- Work PC: power settings may be locked by policy.
Sleep vs. Hibernate vs. Shut Down
