I got last years late MacBook revision. In August I started experiencing problems with the charger. Sometimes it wouldn't charge, and would take a few wiggles to get it to work. Finally, it wouldn't charge it all together. I took it to the Apple store and they said nothing was wrong with my computer, but the charger. I got a new charger and everything has been fine...until now. I've been experiencing the same thing once again So what do I do? My MacBook is out of warranty, but I'm afraid the charger will die for good. Do you think it's a problem with the hardware?
