My Windows 11 (Pro 64 bit) custom-built computer has begun to wake from sleep immediately. The sleep function effectively does not work any more. I can post my computer components/specs if that would help.
The first thing I did was run the Power Troubleshooter, and it made some changes.
When I investigated further I got the information below.
To summarize, Microsoft's High Definition Audio Controller is waking the computer, and there are no wake timers set.
And a day later, when I rechecked, the Microsoft High Definition Audio Controller has disappeared from my Device Manager, but is still causing the computer to wake!
Does anyone have any ideas as to how I can solve this problem?
