Monitor is black and won't turn on.
I have a MacBook Pro and last night it was not working properly. I may have had too much open and the circle was turning endlessly, so I shut it off. Now I can't get it to go on and the monitor part is black. It briefly turns off when I push the power button but then it turns off. I tried to go into Safe Mode but it isn't doing anything.
My Mac was bought in Dec. 2012, so it's not old. Is it under warranty?
