Sleep Mode is one of the most valuable features of the Windows 11 operating system. It puts your device in a low-power state and lets you get back exactly where you left off.

It’s a great way to save on electricity without turning off your system and avoids the hassle of having to open all of your apps again.

It’s best used when you’re away from your computer for a short while. The Sleep mode, like hibernation, ensures that your power supply unit doesn’t overheat from extended use.

Users have reported that sleep mode is not working on their Windows 11 devices.

In this guide, we will show you the best ways to fix issues with this superb feature on Windows 11.

Why does my Windows 11 not sleep?

If Windows 11 is not entering Sleep, it might be because of outdated display drivers. You can fix this by updating them manually or with a dedicated tool.

Wrong power settings can also cause this issue. You only need to adjust it here, and things should be back to normal.

What are the differences between Sleep and Hibernation mode?

Windows 11 also has a hibernation mode that is similar to Sleep mode but has a distinct difference.

Whereas Sleep mode puts a computer in a low power state, hibernation mode has the computer take in a minimal amount of power while saving all the current settings on the hard drive. After that, it enters a state of being almost entirely off.

Hibernation mode takes a bit longer to turn on when the computer exits this state. You use this mode when you aren’t using your laptop for an extended period but don’t want to lose anything.

Check our excellent guide for a more detailed comparison between hibernation and Sleep mode.

How to fix Sleep Mode not working on Windows 11?

1. Set Sleep mode time manually

  1. Open the Windows Start menu by clicking the Start menu icon in the taskbar.
  2. Search for the Settings icon and click on it.
  3. Click on the System tab.
  4. In the System section, scroll down to the Power tab.
  5. In the next window, click on the Screen and sleep option.
  6. Customize the specific time the computer will be put to sleep.
  7. After the time has been set, close the window.

If the Sleep mode is not working automatically on Windows 11, it might be because the time settings are too long. By setting the timer yourself, you should be able to fix the issue.

2. Edit power plan settings

  1. Click on the magnifying glass icon on the taskbar to bring up the search bar.
  2. Type Control Panel in the search bar.
  3. Open the first entry you see.
  4. In the Control Panel window, click the Hardware and Sound option.

  7. Configure the settings to the desired time the computer will go to Sleep. As seen in this example, the display will turn off after 5 minutes, and the computer will sleep for 10 minutes.

If the processor fans are still running after activating the Sleep mode on Windows 11, it might be down to your power settings. This fix should restore normalcy in this case.
