Hey there, My macbook pro won't turn on. It ran out of battery the other day, and ever since, it won't turn on, plugged in to the wall, and have tried pulling the battery and seeing if it will boot off a wall charge. The light on the cord turns orange when I plug it in, but never goes green. Any suggestions? ps. I have used multiple chargers on it so I know its not the charger thats the problem.
