    Hi everyone, I stupidly tried to power on my MacBook Pro 15" (mid 2012) 2.6ghz, after some beer was split on it. I noticed my MagSafe adapter only had a dim green light and wouldn't charge. After drying it best I could I noticed part of the logic board near the fan and charger area (photos attached) had visibly burnt out and a small amount of smoke had come out. What part of the logic board is this and does it basically need to be replaced as I suspected?

    Cheers!

    You can try carefully cleaning the affected area; maybe get yourself a hold of something similar to Akasa AK-TC and a toothbrush with very gentle bristles. Slowly scrub away with the cleaner until the corrosion is no longer visible. Then leave it to dry for a day and gently clean again the next day. Then leave it to again dry.

    Then you can try turn back on, with fingers and toes crossed, that it will jump back into life. Otherwise the MLB itself would need to be replaced, I suspect. I don't think there's a way you can replace the individual affected components.

    Apparently, you can replace individual affected components.

    I guess if you have a soldered station and an ultrasonic cleaner, you can watch Rossman's videos and repair it yourself.

    Otherwise, you might have to sent it to him (or someone else who do logic board repairs).

    I also noticed there was some corrosion around the DC power board so I gave that and the logic board a clean with some isopropyl alcohol. Plugged it in a couple of hours later but it still wouldn't charge up and still has the faint green light. :/

    The smoke indicates that something shorted out. I fear you are going to have to start replacing some components to get this to work.

    Yeah, I just don't know which part. Haha. I've bought a dc power board though which I hear can be the main culprit to a lot of these issues
