Why does my device begin to boot then shut down?
I found an old Macbook Unibody A1342 in my basement and I’ve been trying to get it working. I’ve tried booting from a flashdrive but had the same problem. I don’t think it’s the display because I hear the fans stopping and there’s no OS sound. My device also does not charge to 100%, which led me to thinking it was the battery, but I can’t boot by just unhooking the battery and plugging in the charger.
