Hey guys! I know that this thread has been done to the moon and back so I'll try and keep it as summarised and well informed as possible. Victim: Macbook Pro, 15 Inch, 2010 Model, Model: MC372LL, Logic Board: A1286 Scenario: Laptop was sitting on bed, and I knocked glass of water over. The water spilt on the bed towards the back end/magsafe side of the Macbook. I quickly picked it up and turned it so that the back end pointed down and tried to get all the water out. At that point the Macbook turned on as I lifted the lid to get the water out, and therefore came out of sleep mode. I took the back cover off as quickly as I could and dried it. I let it sit there under a fan to try and get rid of any excess moisture and left it like that for the whole night. During the earlier part of the drying, there was a hissing/buzzing sound coming from the magsafe area of the Macbook, but I was't able to pinpoint exactly where it was. Diagnosis: So this evening after letting it dry for nearly the 24 hours, I gave it another try. It didn't boot up, nor respond to any keys. I plugged the magsafe charger in and there was no light, neither green or orange; everything was dead. I gave the power capacity button a try, but it displayed nothing. Not even one little green light to give me hope. So then I began surfing the web, near and far to get all the info I could, and diagnosis steps. I was able to deduce that the Magsafe charger works, as it powers my brothers 13 Inch, and does it to full capacity ( Went from orange to green after I let it charge up). I then turned to the Macbook itself, and assumed it would be something along the lines of the magsafe board, the logic board, or the battery. I took everything apart with the instructions and disconnected all the components. I wasn't able to find enough information on the testing side of everything, including testing the fuses etc. though I do have a multimeter. Due to that I didn't end up testing the logic board etc. I did give everything a good clean and dry with compressed air; and I know I should clean it with isopropyl alcohol, but didn't exactly know how to go about it. Alas, after giving it a clean with the compressed air, I rebuilt and reconnected all the components of the Macbook. Now when I gave it a try, same thing happened; doesn't boot up, magsafe charger displays nothing BUT the battery capacity lights now light up ( this has given me hope ) and it lights up about 80% of the lights as that's probably how much the battery had charged when the incident occured last night. I did a bit more reading and did a SMC reset, but it seems like there's no point to that as Macbook doesn't actually respond. Now: Now I'm not to sure how to approach this all. I am more than happy to take it apart and test fuses etc. with a multimeter but I'm not exactly sure which ones etc. It might be a magsafe board fault, and I'm more than happy to take the board out of my brothers Macbook Pro and see if it works. Are there any other steps/diagnosis I can do on it to deduce the exact problem? Or should I give up and assume that it is a logic board fault ( touchwood it's not ) Any help would be appreciated guys!
