My Retina MacbookPro will not charge unless it is COMPLETELY dead. Meaning I have to wait a couple days after it reaches 0% battery, then once I plug it in, it will charge. Otherwise it will not charge at all, it won't even turn on if I plug the charger in and it's only been dead for a few minutes. Please help! I can't take the computer to the Apple Store till next weekend due to time constraints.
