    Sounds like you need a #1SMC Reset

     

    1. SMC reset

     

    >>Instructions to reset SMC

     

    Disconnect other non-Apple and external hardware except (if applicable) a mouse and keyboard until your finished repairing your machine.

     

    Problems solved: Fans blowing with no activity, machine is not booting, power button pressed and nothing happens, problems with indicators, Magsafe has wrong lights, battery is not charging, monitor and graphics issues etc.  If the battery is not charged (from like letting it sleep too long), let the Mac charge up awhile afterwards.

     

    Will not hurt the machine resetting if it's not broken.

     

    Other related hardware problems (optional):

     

    Check battery status: Hold option/alt key down while clicking on the battery icon in the menu bar, top right corner.

     

    Magsafe: Use the correct/matching power supply charger with your Mac, not a less powered one from another Mac.

     

    Apple: Laptop won't power up   Apple: Computer won't power up  Troubleshooting optical drive
