Last week, my wife noticed her Macbook Air wasn't charging. We found a small fray in the cable near the brick, and I immediately covered it with electrical tape. A few minutes later, she noticed it was also frayed near the Magsafe connector, so I covered that with tape as well. As the days went on, it was harder and harder for her to charge her Macbook. I found that if I twisted or bent the area near the brick, I could make it work. A day later I was doing just that when I was burned. That spot was really hot and had melted through the electrical tape. I've attached pictures. Last night it shocked my wife when she was trying to get it to work. I've read this is a fairly common issue with these chargers. I plan to go to my local Apple Store today and complain, but as her computer is two years old, I don't think they will capitulate and give me a new one. Who can I complain to about this? Wasn't Apple sued for a similar issue with the old Magsafes? I'm really frustrated and don't want to pay $80 more for an inferior product.
