All, The Power adapter on my MacBook Pro is about to drive me up the WALL. Sadly, however, my warranty expired in July, and I am much too cheap to have purchased an extended warranty. I understand that Apple is now replacing some out of warranty MacBook Pro power adapters with fraying issues. Well, mine isn't fraying, but nothing else about it seems to work properly. A short list of the problems: 1) Computer frequently reports "Not Charging" while power supply is connected (although the computer actually appears to be charging at the normal rate...) 2) LED light comes on only sporadically. 3) Laptop frequently simply stops charging and reverts to battery. Only constant jiggling with the cable at both the power supply end and the laptop end fixes this. 4) Power supply will, for extended periods, simply refuse to work. No amount of jiggling fixes this. I don't have any exposed wire, but the unit is obviously bad. It's an old, larger, rectangular power supply. It's out of warranty now, and the nearest Apple Store is an hour's drive away. It's worth the drive if they'll replace it for free, though. What do you think? Should I take it up, or just buy a new one? Anyone have any experience with this?
