First i would have to ask if you can turn on you MacBook while is pulled in, if so the charger itself is fine. The problem would be in the battery. If it will not power up while pulled in you would need to test it with a volt meter to see if it supplying power or not. If it is supplying power then the problem lies in the computer and there are many guides to help you repair it.
