I woke up this morning and my computer was dead so I plugged in the cord and still nothing. The light was green on the piece that connects to the computer but I also noticed when i took the plug out of the computer (while still connected to the wall outlet) it stayed lit green. Usually that isn't the case so I'm not sure what that means. I have an external battery charger which was able to charge the battery and the macbook is running on just battery right now. Is this a problem anyone is aware of with the Chargers? Will apple replace under applecare?
