I just removed the battery from my MacBook Pro, and it will not turn on when plugged in. The battery removal was necessary; it was very swollen. I have the original charger, and I have plugged the MacBook in as if I was charging it. However, it will not show any signs of turning on, besides the green LED on the charger. Does anyone have any recommendations as to how I can fix this issue?
