Open it up and disconnect the battery from the logic board.  Removed the Mag-Safe adapter.  Press and hold the power button for 5 seconds.  Reconnect the battery.  As soon as you reconnect the mag-safe you should get a spontaneous reboot.  This failing, I need a detailed history of any problems you've had with the machine.  Did you get a full install of ElCapitan?  Has it been working?  Been getting any spinning beach balls while trying to do things?  Any liquid or impact damage?  Do you have a paid for anti-virus protection program running.  When you press the power button do you get anything, lights sounds?
