Burnt MagSafe pin, not charging

[eperezf]

Hi,

I have an early 2011 15' MBP with the original charger. It was working fine until it suddenly stopped charging. I tried different outlets and rotating the magsafe connector but there was no LED or charging.

I saw the connection between the MagSafe an the MBP and there was a burn pin that didn't go back to the original position. Also, the same place was burnt on the socket side. Now the mac will not charge at all. 🙁🙁

Here are some pictures:

I have a few questions:
What could have caused the faliure? The cable was a bit frayed and fixed with tape.
Is it possible that the faliure was caused by the MagSafe section inside the Mac? That means i'll have to buy a replacement and charger.
Is it safe to use a spare 60W charger instead or it will also burn? I know it will charge only when it's off. At least to make a copy of my important files to work on another computer meanwhile.

The Mac kept running after i realized so at least the logic board is not dead (phew!)

Thanks for the advice! As it's my working Mac, I need it running as soon as possible!!

Looks like magsafe connector on the MBP is now shot and I do believe that is soldered onto the logic board so the only way to repair this, is to replace the logic board.

As for the cause, I have no idea, a short and/or higher voltage then designed could be the cause but I'm not sure to be honest.

Bummers man 🙁

I searched on ifixit and it's not soldered. I'll buy a replacement anyway and repair it just in case

Yeah probably all you need is a Power Port replacement.

And a new charger?

Likely. Was strictly commenting on macbook parts needing replacement.
