Hello there. I understand that are a million resources out there to help people who have spilled something on a computer, but I haven't been able to find anything that relates exactly to my problem. Anyway, since I'm a bit of an idiot, I managed to spill a really small amount of water, and I mean really small amount, on my late 2009 Macbook. I did the usual, power off, flipped upside down, leave to dry for a week trick, and the computer itself seems to be working fine now. When I plug in a USB keyboard. Without it, however, it's being very odd. At the login screen, it looks as though I'm typing, but even keys such as enter and shift and showing the dots of hidden letters. When I try typing on any other document however, nothing comes up at all. Just sounds as though it's a bit broken with that, doesn't it? Well, when I went on to play a game on it today, using the USB keyboard of course, I accidentally started pressing the WASD keys to move my character around. And it worked. But it still won't allow me to type elsewhere. I truly have not got a clue what's wrong with this thing, but I'm worried that it's a serious problem with the computer. Could it be my logic board? I'd really appreciate some help cause this is killing me here, I can't afford to buy a new one to be honest, so I'm hoping there's a cheap fix to this. Thank you very much if you read this.
