I've taken the computer into Apple 2 times now and my warranty JUST expired.. The magsafe adapter broke so Apple replaced it with a new charging brick. It's really inconsistent but sometimes it wont charge (the light wont even illuminate.). It's not shorted out and when I took it to Apple, it worked fine... It's working most of the time but it keeps messing up. What do I do? I don't want Apple or Windows opinions, just a cause and a fix or maybe someone that has had the same issue.. Thanks
