Computer was on log in screen, I left the room and came back and computer was off and won't turn back on please help.
I turned on the computer, the log in screen came up. I left the room for around 10 minutes. I came back and it was off. I have electricity working but my computer won't turn on. Is there a way to reboot the computer? I have a mid 2011 iMac osx 10.7.5
iMac, Mac OS X (10.7.5)
