MacBook Air won’t turn on but charges
My girlfriends macbook broke and the 3rd party apple techs said it was the mother board. I did some investigation myself and saw no power coming in through the charger, so I bought a part online and replaced it. So far so good. It wouldn’t even light the charger up before, and now the charger lights up green then orange like it should. The first time I did it, the Macbook immediately turned on and I heard the boot up music. Now it won’t turn on. It’s still charging.
What can I do?
