Fixed my laptop not going into standby


A while ago my laptop wouldn’t properly go into standby mode anymore; the screen turns black but the whole laptop would go into overdrive with only a hard reboot as solution to bring it back up.

Apparently this is because of a feature called Modern Standby that’s enforced since a more recent Windows 10 update. You can check with “powercfg -a” in a command prompt to see which sleep states are available with S0 being the Modern Standby and S3 being the classic standby.

C:\Users\steve>powercfg -a
    
The following sleep states are available on this system: Standby (S0 Low Power Idle)

If you’re having the same issue and it mentions S0, it might be worth a shot to try the following registry key:

  • regedit to HKLM\System\CurrentControlSet\Control\Power
  • add a DWORD PlatformAoAcOverride with value 0

Or this command in an elevated command prompt:

reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0

Do a reboot afterwards and check with “powercfg -a” which state is available, and also check if it solves your problem, it worked for me!
