Why does my machine sometimes instantly come on from sleep? (lemmy.world)

About 50% of the time, if I choose sleep, it turns back on as soon as it shuts down. This can happen a couple times in a row. Other times, it sleeps normally and only comes back on with keyboard input. I’ve looked at running processes and there doesn’t seem to be anything I dual happening at the times it starts back up. Any ideas?

Run "sudo dmesg -w", put it to sleep and then look what the kernel tells you why he could not sleep.

Cool, I’ll try that!
