Prevent Mouse and Network Adapter From Waking Your PC

Some users have found that this issue arises as a result of their mouse and/or network adapter. These can interfere with sleep mode to constantly keep your computer on. It gives your computer no release, no peace. To stop this:

  • Go to your Control Panel and open your Device Manager. You can also access this by typing Device manager into Windows search.
  • Go to Mice and other pointing devices.
  • Right-click your mouse and select Properties.
  • Go to the Power Management tab. Look to see if the check box next to Allow this device to wake the computer is ticked. If it is, untick it, and press OK.
  • Rinse and repeat for your network adapter.

Disable Fast Startup

While in theory, this helps your PC to boot up faster after a shutdown, it can inadvertently mess with sleep mode. So disabling this feature may remedy the situation.

  • Open your Control Panel and go to Power Options.
  • Select Choose what the power buttons do on the menu on the left.
  • Click on Change settings that are currently unavailable.
  • Uncheck the box marked Turn on fast startup (recommended).

  • Right-click the Start button and select Windows Terminal.
  • In the console, type Powercfg /Requests and hit Enter.
  • From the subsequent list of results that display, close any apps or programs that are stopping your PC from sleeping.
