My wife and I always leave our MBP plugged up when we are near a charger. This morning the MBP had been plugged up all night, but the battery was dead. I noticed the light was out on the charger so I went to take it out, but when I touched it it turned red indicating that it was now charging. It turns out it is very finicky and randomly stops charging. Anybody else had problems with their charger? It will be Thursday before I have a chance to get to the Apple store.
