Magsafe connector Scalding hot when charging
I too have the problem of the 85W Magsafe 1 connector getting scaldingly hot charging the MBP either when its on and open or when its closed and hibernating. The connector is cool when charging powered down. To eliminate Magsafe problem, I test with new original piece - same results. Battery is new.
Of the 5 pins inside the (Old) Magsafe connector and the DC-in Board (where the Magsafe magnetically connects to the MBP) the 1st and last pins are black, and not shiny brass. I sometimes have to jiggle the connector before the green and orange lights come one. I will try cleaning the contacts with isopropyle alchohol and report if the discolouration cleans off.
Could the problem be with the Magsafe DC-in board? How can I tell for sure? What will happen if I just continue to use the new Magsafe with the old board and ignore the hot hot connector?
Thanks for the support.
