My custom-build desktop had an issue with the previous AM4 motherboard I had where if you told Windows to hibernate, the entire machine would shut down as normal, but then a few seconds later it'd wake back up by itself and unhibernate. I had to turn off the PSU power switch during those few moments to keep it in hibernate mode. New mobo and that's gone now. BIOS updates never helped. Really odd.
- iamtedd 2y agoProbably no help to you now, but if someone has a Windows machine that keeps waking up by itself, you can see what triggered the wake by running powercfg /lastwake in a command window as admin.
- burnte 2y agoTrue, and that helps if it won't go to sleep. This was some weird bug in either the board or the bios.
