Won't power on, replaced DC-In boardI had the same problem with the scalding hot MagSafe, but I must've killed something in my Mac, because now it won't turn...
"Magsafe connector Scalding hot when charging"に関する回答I ended up replacing my Magsafe DC-in board port. It wasn’t as difficult of a process as I thought and I’m using my Mac again to respond to this thread. I ended up replacing the Magsafe connector as well. I had scalded that so bad and burnt up that I was scared to use it without replacing the connector. I ultimately just spliced the new connector wire to my old one, so now my cable is nearly twice as long.
