Windows 10: Screen fuzzy after wakening from sleep mode, then config errors on restart

My Lenovo T14 laptop using updated Windows 11 has developed problem when starting back up from sleep mode. Intermittently, the awakened screen is fuzzy. When I restart, I see an error message: Configuration error. Restart. On a second restart, everything seems normal again. I can't tell where the problem is, based on troubleshooters and reading MS help files. Clearly, this is some sort of software error, but what kind and where I find it, no information.Any ideas?

Pc restart after exiting sleep mode

well if it works within 5min, sounds like it could be losing power

'restarts after exiting sleep mode' do you mean it acts like a fresh cold boot? or you see the windows logging off screens, then it restarts?

i never use sleep or hibernate, risk of losing the session & waste of hard drive space

 

Windows 10 - Problem waking up from sleep mode

This worked for me on a Lenovo Horizon2 27 all-in-one PC that was able to sleep manually but could not be wakened once sleeping after upgrading to Windows 10 Home.

I ran the powercfg /energy and examined the report as GoWMike describes. It showed no driver errors but suggested that there is a problem with the system's "High Performance" power setting that may prevent normal waking from manually induced sleep.

I used powercfg /list to show available modes, copied the GUID for Balanced mode, and then used this with the powercfg /activate command to change the plan.

I also used powercfg /devicequery wake_from_any

to get a list of device names for components capable of waking the system from sleep, and then I used

powercfg /deviceenablewake <devicename>

to make certain that the touchscreen and power button are armed to wake the machine.

After restarting, sleep and wake then functioned properly again.

 

Getting to sign on screen from sleep mode

Hi Kirk,

For us to isolate your concern, we would like to ask you a few questions:

• What were you doing on your device before performing sleep mode?
  
• Can you verify if you're just only seeing a blank screen after putting your PC in sleep mode?
  
• Did you encounter any error messages?
• Can you tell us the troubleshooting steps that you've performed?
  

Looking forward to your response.
