PC wouldn't sleep
If your PC won't stay asleep it's often because a device is configured to bring it out of standby when triggered.





  • Identify the culprit by pressing the Windows key and [R],
  • type "cmd" and
  • press [Enter].
Now press the Windows key and [R] again, but this time type "devmgmt.msc" to open Device Manager. Find any devices listed earlier,

  • Type the following line and press [Enter]: powercfg –devicequery wake_armed
  • Then double-click them and look for an Advanced or Power Management tab.
  • Check if the device is allowed to bring the PC out of standby – if it is, untick all the boxes that wake it.
  • Click OK,
  • Close Device Manager and test it worked;
  • Repeat the process if necessary.
