I'm trying to work out if my computer has actually fallen asleep, I have set it to fall asleep, but it restarts so quickly, I cannot tell if it was actually having zzzzs or not.
What logs are there to tell me when and if my PC fell asleep?
Oh I found it, only minutes after posting this.
The last and first logs entries upon sleeping/waking up
This command (from the commandline) also lets you know what is keeping your PC awake (if anything)
