"MacBook air won't boot"に関する回答I've had this problem with PC laptops that have built up static electricity and I've had to discharge them by removing the battery and pressing the power button for 10-15 seconds to discharge any build up. The best I can come up with for a Macbook Air is to reset the SMC (System Management Controller) since the battery is not easily removed. This is also listed on Apple's support site for possibly helping with your issue: 1. Turn off MacBook Air. 2. Connect the power adapter and plug it in. 3. On the LEFT side of the keyboard), hold down Shift, Option and Control. 4. With the other keys STILL HELD DOWN, press and hold the power button. 5. Wait 5 seconds, then release all keys. 6. Push power button to turn your MacBook Air back on. Please let me know if this helped.
