A few weeks ago, I can't remember exactly when it occurred (May have been after installing W11) my screensaver and display sleep functions just completely stopped working. I have tried every trick in the book. I have updated my BIOS and chipset drivers. Powercfg -requests shows an audio stream running from realtek, I tried overriding it but didn't solve anything. I confirmed every power option setting is correctly enabled. Basically I've spent extensive time googling and troubleshooting this to no avail.
The one thing that did fix it was running the DISM restore commands in CMD Prompt, however, it only works temporarily for the initial reboot after running that command, and then it stops working again if I reboot a 2nd time.
What can I do to fix this problem?
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
So read through the 12 pages of comments.
What I found that works is running a window (cmd) as admin and screensaver works. If I run it as user it doesn't work.
So I tested this theory with Chrome and same thing. Look like it is a permission issue.

Do you mean leaving your PC idle with a non-admin cmd window open causes your screen saver to stop working? Implying that apps running without admin privileges could block the scrensaver...huh
I finally fixed my issue and now both the screensaver and sleep functions are working again. I was scouring the web and the solution that worked for me was to:
- Press Win + R to open the Run dialog.
- Type cmd in the box and press Ctrl + Shift + Enter to launch Command Prompt with admin rights.
- Input the following command and press Enter. powercfg -lastwake.
Then I looked at the list of devices and went into DEVICE MANAGER (type Device Manager into the command prompt) and went to each item on the -lastwake list. I then right clicked on each thing, clicked PROPERTIES then clicked on the right tab POWER MANAGEMENT and unticked ALLOW THIS DEVICE TO WAKE THE COMPUTER. I had about 15 things on the list. I did the above for everything but the keyboard. So to wake the computer I just whack the space bar.
I'm not sure which item was causing the problem as I turned them all off at the same time but it had got to a point where I'd activate SLEEP and the PC would wake itself up again in seconds.
I did the above in June and now at the very end of August I'm still all good so for me this was a permanent fix.
I hope it helps someone else.
My wake history count is 0, so this isn't the source of the problem for me.
I don't know why it worked that one time...It hasn't worked ever since.

I had the same experience as DavidHasko. I'm running Windows 11 Pro 22H2 pre-installed on a mini-PC.
I had no problems with the screen and computer not turning off and going to sleep when I used a Logitech keyboard and mouse with a Unifying receiver.
I decided to swap the Logitech keyboard/mouse with an older Microsoft wireless multimedia keyboard/mouse that uses a USB wireless optical desktop receiver 2.1. The MS keyboard/mouse/USB receiver worked fine on a Windows 10 computer. However, when used with my Windows 11 PC, the computer stopped going into screensaver mode and sleeping.
I was about to buy another Logitech keyboard/mouse when I looked under Settings > Windows Update > Driver Updates and saw a few optional updates (This is with the MS keyboard/mouse/receiver plugged in). I updated all of them and saw afterward it installed a couple of Microsoft HIDClass device drivers and a Microsoft Mouse and Keyboard Detection Driver (USB). After the update, the screensaver and sleep mode started working with the MS keyboard/mouse/receiver as they did with the Logitech keyboard/mouse.
