Windows 10: My Windows 11 machine is unable to get into sleep mode Intermittently

My Windows 11 machine cannot get into sleep mode. I found the display goes off and the CPU remains On CPU light remains On. When I try to wake up, the machine display doesn't come back. It says no display. I have to power-drain the unit and restart it. I am not sure what is it that prevents it from getting to sleep. Its almost a brand new Windows 11 setup and the only software I have installed is Adobe Suite. Please suggest how to troubleshoot this issue.Hardware/Software Configuration----------------------------------------I am using Intel NUC PC. Windows 11 - With all software updates - O

Hi Abhishek,

Thank you for posting on Microsoft community.

• Since from when are you facing this issue?
• Did you make any changes prior to the issue?
• Are you able to shut down or restart the machine?

I would suggest you to force shutdown the computer and start the computer and check what happens.

If you are able to login to normal mode then follow the below steps to restore the power setting/plan to default.

  Control Panel.
• Click on the Power Options icon.

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!
