I just recently upgraded my 2010 macbook pro RAM. I went from 4gb to 6gb and now my backlit keyboard is no longer working. I have tried messing with the keyboard settings as well as the F5 and F6 buttons. The keyboard does not even come on in low lit conditions. Why is my backlit keyboard no longer working?
