Hi! I have a problem with my magsafe. It was working like a charm until today. I was working on my mbp and then I hear a loud pop from the power brick and now it's not working anymore. When I shake it something inside is broken... I haven't dropped it or anything so i have no idea what the problem is. It wasn't a power surge... Everything else in my home works perfectly and the circuit breakers are ok.... Do you think Apple will replace it? Any body have any experience with the issue?
