Over the last couple of days I noticed the MagSafe connector was getting quite warm and the led in it was flashing between green, amber, and nothing at all. Today, I saw my battery was not charged 100% and it should have been having been plugged in all night long. I reached for the MagSafe, and it was too hot to hold, when I moved the cable, the green led came on, followed by the amber, then off again. I unplugged it, removed it and investigated. The rubber covering over the cable right at the join of the MagSafe had melted exposing electrical wiring.
Considering those things cost around $100, I now only 'need' $200 worth of defects to make the AppleCare extended warranty pay for itself...
Thankfully, the helpful Apple staff said they would send me a new one within 24 hours. I am at home sick with the flu and have to use this sick time constructively... Catching up on all those old tv series I have missed over the years and sleeping... Love that HBO but running those video files sure go through the battery power fast... have to keep borrowing my nieghbour's power supply.
