Here at my LAS (local Apple store) with my White Macbook charger that has a minor nick in it (that I didn't do nor do I know how it was done). If you plug it in and move the cord slightly, the exposed wires will spark. I've also had numerous other charging issues with this charger before. The computer and charger are still under the one year warranty with about 1 and a half months left and no AC. This charger is not abused nor is the computer. My LAS has quite a record of me coming in complaining about the charger not charging but once it sits unplugged from the computer and the wall for about 10 minutes, it works fine. In addition to that, I've had plenty of other issues with this charger and all have been within the one year warranty period. I have an appointment for Thursday but I thought I would come by this evening since I started sparking this afternoon. I was told that since the cord/charger didn't actually catch on fire, they can't do anything about it even though the thing almost caught my kitchen table and table cloth on fire. Should I demand a replacement from the manager or should I just fork over the $80 for a new charger? Thanks.
