MacBook Pro not turning on, please help!!

I have no clue what is wrong with it. I shut the screen so I could move the computer to my room, then bam. Nothing. It's like it's dead. I didn't do anything to update it or add anything to it. It is a MacBook Pro 15in from 2011. The battery buttons on the side don't do anything. When I plug the adaptor in it doesn't do anything. I tried to do the command option control and power button, nothing. I tried the power button plus shift whatever p and r, nothing happened. My life is on the computer, I need it to work. Please help!!
