The charger light comes on periodically and charges but now it won’t. I had to move it around and by luck it would get it just right to charge. Do the magnetic pins wear down in the charger or the laptop?
It could be the pins on your charger if it it the original. I have the same issue with my older MacBook Pro(2009). You could try replacing the DC in board, or using a newer charger if it really bothers you.
the pins don’t wear down, but the springs. as you have to move the coil around, it could also be a break in the cable itself, usually the plus cable. try a different charger, check for differences. post.
