Windows 10: Window 11 cannot enter sleep mode

Hi,I have Windows 11 installed on my PC, which has started to immediately wake up from sleep after being put to sleep. How do I fix?

Windows 11 Desktop Won't Enter Sleep Mode

I upgraded to Windows 11 last fall (November) and for the most part everything has been working ok. Within the last month, I've had an issue where my desktop will not enter sleep mode. If I select sleep, my keyboard and mouse will shut off but my desktop will idle with the fan periodically cycling for about ten minutes before the desktop shuts off altogether. The only way I can turn my PC back on is by using the power button, which reboots the device.

There are two other issues that have started around the same time, which may or may not be related to the above:

• when I connect to my second monitor, a number of icon images on the start bar on the second monitor won't display
  
• a few times while using Google Chrome, my PC slows down considerably, the memory used by Chrome maxes out in Task Manager (and stays maxed out even when I shut Chrome off), and I am unable to see anything I type in any application I have open (not just Chrome) unless I alt-tab between applications - I have to restart for my PC to become usable
  

I've tried a number of suggestions related to fixing the sleep mode issue but none have worked for me so far. Here's what I've tried:

• Run the power troubleshooter
  
• Disabled my network adapter from waking the computer
  
• Using powercfg to disable processes that disrupt sleep mode
  
• Disabled fast startup
  
• Tried a clean boot and had the same issue
  
• Updated the latest drivers, Windows 11 updates, and BIOS version
  
• Disabled hybrid mode
  
• Scanned for viruses
  
• Ran system file checker and DISM tool
  
• Deleted the hiberfil.sys file
  

I have a X470 Aorus Ultra Gaming motherboard and AMD Ryzen 5 2600X CPU. Any thoughts or suggestions on other things to try would be much appreciated!

Windows 8.1 does not enter Sleep mode

Since a few weeks my computer incorrectly enters Sleep mode from Start->Power menu.

A few weeks ago, in Sleep mode:

1. The power led was blinking
2. Monitor went black
3. After moving mouse monitor turned on and I needed to enter Windows password

Now in Sleep mode:

1. The power led is on all the time
2. Monitor goes black
3. After moving mouse I am back in Windows, not prompted for password

This is a fragment from my motherboard manual:

PLED (System Power LED):
Connect to the power status indicator on the chassis front panel. The LED is on when the system is operating. The LED keeps blinking when the system is in S3 sleep state. The LED is off when the system is in S4 sleep state or powered off (S5).

This means that after pressing Sleep, Windows is not entering S3 sleep state (as it used before), because the led is not blinking.

This problem is not influenced by choosing (in Advanced Power Options) to allow
hybrid mode on or off nor by choosing to allow wake timers on or off. I tested all combinations and it's still not entering Sleep.

If after two hours of doing nothing on the computer I choose the Sleep mode and then after a minute move the mouse, then in the Event Viewer, in the summary of administrative events there is only one event in the "Last hour" column:
Microsoft-Windows-Kernel-Power with eventID 59 and it says that computer entered away mode.

In my Bios there are some settings which may influence the power behavior. They didn't change since long time and I think they are ok:





Is there any way to help figure out why the computer doesn't enter S3 mode anymore? And how to fix it?
