Well, I was just on the computer for 2 hours and I just put the computer in suspend mode. When I usually wait for it to go into it automatically. (wait for display to turn fully off) It didn't and I turned off the laptop and turned it back on. Then the ubuntu splash screen came up. Said something about one of my files or disk named /tmp. It gave me some options (something like this) skip, something about unmounting it, or find problems.
I clicked find problems/fix. It had a screen with 95% of 100%. It went up to 97% then the computer shut off and restarted without a problem.
Does anybody know what happened or what I did to make it do that?
