I've seen similar questions already posted, but I had to ask since they're kinda outdated.
In the evening I'd put my PC to hibernation. Browser and XAMPP are on. And around 3:15-3:45 at night it would turn on by itself (and wake me up). Not every night, but often. I turned of Wake on LAN (at least I think so) as suggested on other threads, but it
still turns on. It's most probably network related, for last two nights I've put it on hibernation and unplugged the network cable and it didn't turn on.
I think this started with 1909 update, but I couldn't be 100% certain, I didn't use hibernation much until a month ago.
Any ideas?
EDIT: I've found a bunch of possible solutions on different forums, check my reply below. It worked for me.
