try resetting the power management unit on system , see if helps. shut down system. unplug adapter, take out battery , hold down power button ten seconds. put battery in , power up. if still having issue, try resetting pram, shutting down system, holding down buttons p, r, apple (command), , option. while holding down these keys turn unit on. don't release keys until hear 2 startup chimes.
