Water damage, based on evidence, does logic board need replacing?
At the weekend I was caught out in a rainstorm and my backpack containing my MBP receiving a good drenching.
When I got home and checked the macbook, it was unresponsive and the battery indicator lights were stuck on. I made the amateur mistake of plugging it in, and predictably after that not even the indicator lights worked.
Upon opening the back up, I could see a few drops of water near the battery and HDD, but otherwise water penetration didn't appear extensive. I didn't have the screwdrivers to investigate further at the time so I left it to dry out for a few days.
Tonight I finally lifted the logic board out to see what what was wrong. Two liquid immersion indicators near the trackpad are red, and on the underside of the logic board a component next to the RAM slot appears scorched. I strongly suspect this is the culprit. Nothing else looks to be amiss.
Based on the pics I've linked to below, would it be safe to assume that I need to replace (hopefully only) the logic board? I'm confident about replacing parts myself, but not so confident about my diagnostic skills. I'd appreciate another opinion before shelling out for a new logic board.
Is this a good question?
