"Power issue with macbook pro: Hello, I have a MacBook Pro 2013 13 inch (A1502) which is having an issue with the power. Whenever it runs out of battery it won’t turn on again for several days at a time. This time there hasn’t been any sign of life for over a week. […]Which makes me think it’s not just an issue with the battery. However, the power cable will display a green light when the battery is connected and an orange light when the battery is disconnected, so there is something happening there. Does anyone have any ideas about how to diagnose the problem?"
