Reboot reseting the PRAM & SMC, (Hold down: Command, Option, P, R all at the same time, and press Power button. Keep holding down the buttons until Mac restarts 2x and you hear the second startup chime.) If that doesn't work power it down, remove power and the battery for 8hrs, reinstall and try again.
