Windows 10: New PC Won't Enter Sleep Mode

I bought a new PC running Windows 11 Pro. It will not enter sleep mode when I click Sleep from the start menu. The screen turns off, but the fans and RGB lights on my PC stay on and running. Any slight movement of the mouse instantly turns to screen on with no hesitation. I have tried adjusting my Power settings, including advanced power settings. Powercfg/last wake always reports 0 which tells me the device is not entering sleep mode at all.

Windows 10 hangs in sleep mode

turning off sleep mode to force it into hibernate.



What happens with that? It would require you to tap the power switch to wake the machine from the Hibernation state.

Also see if this gives you any new ideas

my computer won`t wake up after goes to sleep

these computer won`t wake up after goes to sleep ?

 

Sleep Mode... It won't wake up!

No go still. *Frown

Thanks suraswami for the suggestion.

Ok. I reset the BIOS to defaults, and S3, and now when I tell the computer to go into standby, it appears to save everything to memory, and then power off. It's like the PC thinks sleep means hibernate.

So, OK. I tried turning off hybrid sleep, and now when I went to sleep, the PC just powered off. And when I tried powering back on, Windows said it was shutdown unexpectedly.

Now I've tried swapping out each pair of 1GB sticks (4 sticks total for 4GB) in all four slots in different configurations. On each time, it displays the same symptoms: When I try to resume, I can hear drives spin up, and the fans will roar to full speed *and stay on full speed*. The screen will remain black, the HD led will not light at all. The power LED remains flashing blue. It will stay like that indefinitely. I have to force power off by holding the power button. So, unless all four sticks of RAM happen to be bad, I doubt this is the culprit.

Any suggestions? S1 sleep mode in the BIOS works fine, although, like you mention, it's not ideal. I can hibernate the PC just fine. I'd like S3 to work, ideally.

Thanks.
