Windows 11 Screensaver / Display Sleep functions not working

I followed your advice and disabled all my startup apps and my screensaver started working. I turned them on one by one and tested the screensaver after turning each one of them on and discovered it was the NZXT Cam software for my AIO that was causing it. Tried updating it and even tried a beta version and none of them worked, they kept the screensaver from coming on each time. This is a windows 11 issue, cause, the software worked fine in windows 10. Just wanted to thank you for the instructions, I've been trying to fix this for weeks now to no avail unitl now, so, thank you!

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.

This is what worked for me. Microsoft wireless keyboard. Using Windows Update, installed the optional drivers, which included the Microsoft HID class drivers. Voila!

I should have reported this back sooner, but it completely slipped my mind.

Do you have any RGB lights on your system and, if so, how do you control them? I had this exact same issue occur and what I found was that a piece of software, controlling the RGB lights on my system, was preventing the system from going into sleep. What I had to do was to completely uninstal the controller software, set up the screen saver / timeout parameters, and then reinstall the controller software.

The way I discovered the issue was by using msconfig to disable all startup apps (except Microsoft/Windows ones) and then restart them one by one until the issue reveals its ugly head. Unfortunately, this can be a long and tedious task, but if you're lucky, as I was, you'll find the offending app quite quickly. There shouldn't be a need to system restart after starting each app, unless they are a service or require a service to run; I would leave these apps until the end, as long as you know which ones they are.

Remember. Once you have disabled them all, AND RESTARTED YOUR SYSTEM, you need to reset the screen saver timers (I would set it to1 minute during the testing phase) and only then start each disabled program/app in turn.

I hope this helps.

Go into registry and uncheck screen saver manually so it doesn't check itself in the energy saving settings. If it is checked in those settings, screen saver will not work on Windows 11 as it is a update and it checks the screen saver button as part of saving energy mode, so just uncheck it in the registry if if won't let you in settings, then your screen saver will work.

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?

Forgive me for being sinical, but Windows 11 came with a lot of problems. Some of mine have been impossible to solve.
