Hi all. I have this macbook that wont power up after water spill. After disassembling, i found corrossion on the under side of the board, but the problem is one capacitor is so badly corroded that a pad is totally burnt out, leaving a hole on the PCB. The cap sits on a shorted line PPVIN_G3H_PP3V3G3H. i have searched for any other shorted components on the line and found none. Now i am starting to think the burnt pad now turned hole is shorted to the ground layer on the motherboard. I read online that drilling through the motherboard at that point will separate bridged layers, but i need to be sure before doing anything else. Thanks.
Can you sew on a button in the dark? This is likely even harder with this logic board. These logic boards are multi-layered I’m guessing five or seven layers. Drilling is very risky endeavor unless you have the board traces mapped out. So you can see what each layer sits. Apple controls their board info quite tightly so that will be very hard to get. If you mess up you run the risk of damaging other elements of the system. I really think the cheaper and less risky direction is just getting a new logic board. Take your pick 2016 MacBook Pro 13” logic boards
