    Hello guys, Im new here. I have a problem with my mac, and I wondering if you can help me. The mac is not charging the battery I tried different chargers but it doesn't work. I opened it and I noticed in the 820-2565-a (charging port)there is a "damaged" element. What is the way to go to verify the source of the problem? Thank you for your help!

    That does look pretty blown to be honest. You could check with a multimeter to see if power is reaching it at all. You could replace that diode, but a new board is about $7 so I would just replace it and see, costs nothing to do and may well solve it.

    I would however attempt to work out why it's happened, perhaps damage or a bad charger. Check the ports and anything connected before that circuit, otherwise you run the risk of further damage after a repair.

    I'm no expert either but that's just how I'd go about it. I believe that diode protects the computer from a power surge, so it could well be a bad charger has fried it (Rather than the computer). Like a sacrificial lamb. Either way, swap it out.

    Common faults:

    Dead external charger (capacitor dies in them). Happened to me.

    Old, dead battery.

    Uncommon faults:

    Board damage. In your case... maybe?
