Why won't my MacBook turn on?

Alright so, when I click the power button, the charger like flicks to green then turns off but the fan continues to run high. No light on the keyboard or screen come on. Any ideas?

Hi Meech,

Try performing an SMC reset on your MacBook Air. Follow these instructions;

  1. On your built-in keyboard, press and hold all of these keys:
    • Shift  on the left side of your keyboard
    • Control  on the left side of your keyboard
    • Option (Alt)  on the left side of your keyboard
  2. While holding all three keys, press and hold the power button as well.
  3. Keep holding all four keys for 10 seconds.
  4. Release all keys, then press the power button to turn on your Mac.

Your mac should then boot up correctly!
