Monitor keeps waking up every few minutes due to "Kernel-Power" event with "Reason Unknown"


I use the keyboard to wake up the computer. You can always use the power switch as well if it's sleeping a quick stab of the power button will wake it.

Ah, ok. My Microsoft compact keyboard doesn't seem possible to wake the computer, even if it has the right setting in device manager.

There's always the power button, I don't know of any machine that doesn't work on. :-)

For me, earlier, it seems to be the windows 11 notifications. I turned it off and it worked. Now it seems to be more less. I got this sometimes it seems with the same message in event log. The monitor wakes up and nothing more happens. I'll try to get all event logs next time it happens.

Maybe something else that wakes the monitor?

I had been experiencing this same issue, with the same mobo/CPU as the OP. All sleep/low-power settings disabled, monitors would turn back on every 2-4 minutes constantly. Thank you for the tip about the notifications - ultimately, I had to toggle off the top "Notifications" slider at Settings > System > Notifications to completely shut them off and then restart. That finally seems to have done the trick - monitors stay off as expected until activity resumes.

Can't find the TID in Process Monitor. Possible to dig any deeper?

Another strange thing that started to happening is when I have the computer in sleep mode - the light on the motherboard goes on. I have turned it off earlier and tried again. There is a bios update, I'll give it a try.
