You can reset your system management controller:

This is how to reset SMC on most modern Mac laptops, none of which have a removable battery:
  1. Shutdown your MacBook Air / MacBook Pro
  2. Connect the power adapter to the Mac
  3. On the MacBook / Pro’s keyboard, hold down the Shift+Control+Option keys and the Power button at the same time
  4. Release all keys and the power button at the same time – the little light on the MagSafe adapter may change colors briefly to indicate the SMC has reset
  5. Boot your Mac as usual
