Windows 10: How to check what cause my PC to Shutdowns after Sleep?

It is happening most of the time. When I try to wake up the PC in 2-3secs it shutdowns. How to check the cause for it?There are old posts that don't help at all - like the Power Troubleshoot one and others.Windows 10 Pro

:)

 

My pc takes for ever to shut down when i restart

Suggest cleaning up your startup list .There may be many services / Apps you can remove on startup which is not needed on boot or during shutdown.
Before you shutdown the Pc check what is running in Task Manager as a program or service in not killing the process on shutdown

Would suggest cleaning up running apps and services -Autoruns, StartupMonitor,HighjackThis,
Malware Scan - Malwarebytes,ADWcleaner, Combofix

Windows Will Not Sleep or Shutdown from Start Menu

Hello! I can't get my PC to go to Sleep, or Shutdown using any of the typically proper methods. When I try to shutdown the PC it starts to shutdown, screen goes black and then wakes back up to the login screen.

I have gone through and disabled all of the devices that might other wise prevent this from happening. I have done the following to try and remedy the issue.

• Check the powercfg -devicequery wake_armed
  • This returns a NONE after disabling devices from Device Management
• Ran powercfg -lastwake
  • Wake History Count - 0
• Opened my Power Options > Multimedia Settings > When sharing media > Setting: Allow the computer to sleep

I have recently completed a clean windows install. One of the changes that I have noticed was that my BIOS now runs in UEFI mode, not Legacy. I'm not sure that this matters or not, but in my BIOS menu, the Boot Manager only list the Windows Boot Manger, not a list of devices.

Thank you any guidance would be appreciated, I would love to be able to Sleep and Shutdown my computer properly again.
