Magsafe connector Scalding hot when charging
MagSafe connector heats up really bad, why is that?
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.

mine was too. too touch to even touch. so i disconnected it. cleaned the connectors with an old toothbrush and noticed that one of the connectors was already depressed slightly. i pushed on it and it didn't click back into position so i tapped the magsafe on the table to try and push it out. and saw that it did. dirt and grime could be the culprit. re attached it. now it's charging again...its heating up the same but not as it did before. seems like i have to buy a new magsafe then.
I too have the problem of getting Magsafe connector hot. My observation and analysis are:
DC-in Board pins 2&4 (2nd from either side) are black. Magsafe connector 2&4 pins are pressed down and not fully popped out. hence these pins while touching DC-in Board connector, do not make full contact. They are making loose contact which in turn makes arcing/sparking which generates heat to make Magsafe hot. It is a typical phenomenon you see on household electric plugs getting fused and burnt. Once I cleaned both sides with alcohol and system worked good for some time.
Other thing is once batteries get old, they need more current to charge. Moreover if you are using your MBP and charging it simultaneously, it will require extra current. That much extra current when flows through connector it is bound to get heated up.
In my opinion if the Magsafe pins are not depressed, fully popped out and make firm contact with DC-in Board, the problem is 90% solved.

I too had this. While checking email Noticed that charging was slow, felt charge port and it was very hot. I lightly pushed in the plug connector wiggled caddy corner as to assure connection and allow connection points to sorta clean themselves and every thing returned back to normal. I will clean the contacts when I get a chance.
