Windows 10: PC won't wake from sleep properly after Windows 11 update

After installing the latest Windows 11 build, my Desktop PC does not wake from sleep properly. It either has a black screen with a cursor frozen in place or wakes in lock screen but both keyboard and mouse are frozen. This is after installation of build 22621.

Troubleshooting PCs spontaneously waking from sleep

I've also battled with sleep/wake issues over the years, and from experience have learned that trying to find, or rationalise, the root cause is a waste of time. All you need is `powercfg`.

`powercfg -devicequery wake_armed` from an Administrator PowerShell window/Command Prompt will give you a list of all devices that can possibly wake the PC. This command is interesting because very often, it will show devices that you'd never expect being able to wake your computer. I think in one instance I had the chipset device listed!

`powercfg -devicedisablewake "device_name_from_device_query"`will prevent said device from ever waking the computer. This command is 100% the only thing I have found that will resolve sleep/wake problems. Updating drivers, unplugging peripherals, switching to a cleaner power supply (UPS), changing ethernet cables... none of those have helped, yet`powercfg -devicedisablewake` has done the trick.

Note that occasionally, devices you have disabled wake for may start waking up the PC again - this happens if you plug a USB device into a different port, or occasionally when drivers are updated, because Windows sees it as a new device. In that case rerun `powercfg` to find and disable that device again.

If this does not resolve your wake issues, I would start looking at power fluctuations.

 

computer won't wake up from sleep...

Update chipset drivers. Also revert all overclock settings to default and check.

A Windows update was there too regarding the BSOD while waking up from sleep on certain HDDs. So check that as well.
