Windows no longer goes to deep sleep - turns monitors off, but fans still running

This is a mini desktop PC with Windows 11. Previously the PC has gone to sleep fine (turning fans off), but I had an issue with it turning on again randomly.

I did some troubleshooting, and the result is that it now does not even go to sleep properly anymore.

When I click Power -> Sleep, the monitors turns off, but the fans keeps going. I have not changed anything in BIOS.

• I unplugged all USB-devices.
  
• powercfg -restoredefaultschemes -> Did not help.
  
• powercfg -requests --> Only shows none.
  
• I made sure ALL devices in device manager has turned ON "Alow the computer to tum off this device to save power"
  

How can I find the reason the computer won't turn completely off?

 

Monitor will not sleep on shutdown


Hi,
I just changed from DVI to HDMI and now when I shutdown my computer my monitor will not enter sleep mode, and will display 'Cable Not Connected' as shown in the image attached. Any help would be appreciated, thanks.

 

Deep sleep problems in windows 10 update 1709

Hello Andre;

This work around did not resolve the issue either nor change any characteristics of the problem. The computer still goes into deep sleep after about 12 to 15 minutes into a game requiring a hard reset each time. And this sometimes results in a corrupted
saved game file as well,.

To quickly recap. I can have my desktop computer on 24 hours a day, go online for work or play, Skype for hours, run applications like Office, Windows media player etc with no problems. Soon as I run a virus free computer game from my hard drive, such
as HOG's, Fallout4 , Outlast, Ages of Empire etc, it goes into deep sleep.

So I removed my Gforce GT430 video card, reinstalled it and re-installed all updated drivers for it, and still no change.

I am thinking of uninstalling the latest windows update 1709. Also I don't no why the computer goes into sleep mode even when all settings say "never" sleep, never hibernate hibernate, never shutdown etc. There is something else overriding this.

Thank you for all your suggestions so far. i don't want to give up on this.

Brian
