So today I was on my late 2010 MacBook pro 15 inch and the charger was charging it perfectly fine. Then I decided to go do something else for a while and when I came back the green light on the charger was off and nothing would bring it back. My computer doesn't even notice that it is pluged in. I have tried everything from cleaning both the charger and the spot it goes into but none of that worked. So now I don't know what to do.
