    I have a macbook pro late 2011. What can cause the power cord to stop working? Overheating? Any thing else?

    Apple's power supplies have a tendency to wear out -- frayed cords, etc.

    Some folks try to repair them, with mixed results.

    Usually the solution is to buy a new Magsafe.

    When my sister needed one, I found one at Other World Computing for $59.

    Beware of "cheap knock-offs" on ebay. They use internal electronics that are inferior, which could damage the MacBook or even cause a fire.

    the power adapter might also stop working when your internal connector on your MBPro is damaged.
    That's the magsafe board, or also called a DC-in board.
    Your best tip is to try another power adapter that you know is working.

    If your cord, or the adapter (the white box that is actually your power adapter) already looks "burnt", then that's likely why, and you would simply purchase a replacement power adapter. Be sure to check for damage inside that magsafe connector. Dirty, or burnt, or simply loose-missing bits inside that opening.
