사용자에게 답변하기: Why did my internal keyboard and mouse suddenly stopped working?15" MBP E button stoped working whila playing a game. I use it for movement and all of the sudden my character starting running sideways as if I were pressing it. I tabbed out and back in. Character stopped moving but at the cost of E button not working. I was thinking of overheating the battery but I use a cooling fan (external) which helps a bit. Temperatures does not seem to be that high, around 60 degree C. Ideas?
