Windows 10: Windows 11 will no longer turn off monitor or put laptop to sleep

On my Lenovo P15 Gen 2 laptop running Windows 11 Pro, this problem happened yesterday. I noticed the laptop will no longer turn off the monitor or go to sleep as per the settings in the power management plan. It stays up all the time. I can manually put the laptop to sleep and wake it up. But it won't do it as it did previously. I have tried resetting the power plan and changing the settings to no avail. I have run the power troubleshooter and came up with nothing. I will try to run the System File Checker next to see if it clears it up. Beyond that, what else can I do to fix this prob

Windows no longer goes to deep sleep - turns monitors off, but fans still running

This is a mini desktop PC with Windows 11. Previously the PC has gone to sleep fine (turning fans off), but I had an issue with it turning on again randomly.

I did some troubleshooting, and the result is that it now does not even go to sleep properly anymore.

When I click Power -> Sleep, the monitors turns off, but the fans keeps going. I have not changed anything in BIOS.

• I unplugged all USB-devices.
  
• powercfg -restoredefaultschemes -> Did not help.
  
• powercfg -requests --> Only shows none.
  
• I made sure ALL devices in device manager has turned ON "Alow the computer to tum off this device to save power"
  

How can I find the reason the computer won't turn completely off?

 

I want to connect the monitor to my windows 11 laptop. I want to work only with the monitor and I tried to put the laptop to sleep but the laptop is sleeping with the monitor how can I solve?

Dual monitors not waking from sleep

Hi all,

I'm having issues where my monitors won't wake from sleep in a dual monitor setup. This only occurs after waking them from a sleep state, and they work fine when booting up my PC from scratch.

I have tested both monitors in a single monitor setup and the issue goes away completely as they wake from sleep just fine when only using a single monitor. This issue only seems to occur when using both monitors simultaneously.

I have tried the below steps to no avail to remedy the issue:

• Changed the DisplayPort cable
  
• Uninstalled graphics drivers with DDU and reinstalled them again
  
• Made sure Windows update was completely up-to-date, including any optional drivers
  
• Made sure there were no unknown devices in Device Manager
  
• Turned Link State Power Management under PCI Express in Power Plan settings to off
  
• Completely formatted my PC and reinstalled Windows 11
  

None of these steps have resolved the issue.

Any assistance provided will be much appreciated!
