Yeah, I haven't either, that's why I said "I'd love to see you try". You'd think the system would be smart enough to realize that it's literally never been awake at 3:30am.

I experience that constantly on any laptop I use because I pretty much never turn them off - they go to sleep mode when not used. Every now and then I find the laptop running with a clean desktop after logging in - because it decided to reboot and install updates somewhen during the night.

I've been an enemy of automated updates ever since, many years ago, I went to the kitchen to boil the water for a tea, and there suddenly I heard the PC speaker beeping - oh, Windows decided to count down from "5 minutes" and reboot.

If the computer is sleeping it can wake up. Not sure about hibernate.
