Did you try to reset the SMC (System Management Control)?

The SMC manages low-level settings, like thermal issues, CUP usage fans, and battery management.
  1. Shut down your Mac.
  2. On your built-in keyboard, press and hold all of these keys: Control, Alt & Shift
  3. While holding all three keys, press and hold the power button as well.
  4. Keep holding all four keys for 10 seconds.
  5. Release all keys, then press the power button to turn on your Mac.
