Last night my roommate was using his 15" MBP when, oddly enough, he smelled something burning. Minutes later he noticed (fortunately before touching it) that the rubber casing on his power supply had burned through and the wire was exposed. This obviously isn't normal. He was plugged into a surge protector, his battery was charging normally, and he wasn't doing anything abnormal - just browsing the web. Nothing had shorted out. He called apple today and was told that this was not their responsibility and insinuated that it was the result of his own "abuse" of the power supply. Personally I think Apple is full of it on this one. It's not normal for a power supply to melt in the middle of normal use. I need your advice. Have any of you experienced or heard of anything like this before? Any ideas on how to deal with Apple? Thanks for your help.
