About a month ago, I've managed to spill some juice onto my MacBook Pro. I've drained it, opened it up and cleaned it. After waiting a day, I've fired it up again and everything worked perfectly. After about 4 days, the keyboard short circuited and got stuck on one key so I couldn't do anything. I've tried cleaning the keyboard and ended up killing the whole keyboard (including the power button). I've ordered a new one off eBay, installed it but for some unknown reason it does not work. It's pretty much the same thing - no keys and no power button. What could be the issue? The logic board works perfectly with an external keyboard but not having a power button is annoying. Is the new keyboard incompatible (the pins on the connector seemed a tiny bit thinner)? I think the keyboard came from the same kind of a MacBook but a different model. Or could it be a logic board issue?
