I am using Windows 10. I always leave my PC on sleep when I am not around and wake it up by pressing any key. This has worked fine until 1803, but in every subsequent Windows update after I put my computer to sleep and wake it up, the screen stays black. I can hear all the fans working and all the peripherals light up, but the screen stays in sleep mode.

Now I have been forced to upgrade to the latest update and I still have this issue. I thought that maybe it was because of the motherboard so I updated Bios. I have ASRock 870 Extreme3 R2.0

What could be the possible reason? Where should I start looking?

This problem has many causes. Below are listed some of them with suggestions.

  • Run the Power troubleshooter

  • Restore Power Plan Default Settings : In Power Options, click Change plan settings, then "Restore default settings for this plan"

  • Turn of Hibernation using a Command Prompt (cmd) run as Administrator:

    powercfg /h off
    
  • Update graphics card driver (download only from the manufacturer)

  • Update BIOS (very carefully, download only from the computer/motherboard manufacturer)

  • Search the BIOS for a function called "BIOS PSP Support" (if exists in your BIOS) and enable it

  • A claimed solution was to use regedit to navigate to the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration, where the resolution is entered wrongly in six entries that need to be corrected. Reboot is recommended, as well as creating a System Restore point before modifying the registry.

  • Although disabling hibernation certainly has a couple of benefits and I always do it on my own PC, I'm pretty sure it wouldn't solve a problem with resuming from sleep. Nov 23, 2019 at 13:07
