My coworker accidentally spilled about a bottle capful of water on to my MacBook 13" Aluminum Unibody Late 2008 (A1278) keyboard. He immediately wiped it up and told me about it. About 5 minutes later, I realized my keys "A" through "L" and keys "Z" through ,"M" weren't working. I shut down my computer, took out the battery, and let it sit open and upside down (like a tent) for the remainder of the day.

The next day I put everything back together and tried the keys again and they still didn't work. Everything else on the computer works fine except those 2 rows of keys.

I've been around a lot of forums trying to read up and find out what my next step should be but am not sure. I took the back piece off to reveal the logic board and dusted everything off - I didn't see any water or visible damage. A lot of people recommend completely taking apart the Macbook (eek!) and blow drying everything. I just need to know:

1. If the keys aren't working now, would they even work if I tried that?

2. If it doesn't work, what needs to be replaced? I hear some people replacing logic boards and others replacing keyboards. Are they connected to each other or separate pieces of the laptop?

Sorry if this sounds confusing, but I need to figure out what to do next because I'm really dreading going to Apple with this issue and paying a ridiculous amount for repair (especially if I might be able to handle this myself).

Thanks for any help!
