Usually, a battery issue will not cause a no power up issues. Batteries in MacBook Air’s rarely swell or short. When you plug it in, I want you to look at the charger light. Does it light up? Unplug it, and hold down power for 10 sec. Put your ear up to the vent and plug it in again. Do you hear the fan spin up?
