If you have the pentalobe screwdriver to remove the bottom cover, disconnect the battery, wait about 30 minutes, connect the charger and see if the Macbook powers up on its own without pressing the power button.

Are the charger and battery working? if I remember correctly the air will not start without a battery.

The Air powers up by itself when the battery is disconnected and charger is connected?

Turn the Air on its side and look to see if the fan starts and stops or it starts off at full speed and then slows down.
