Hi,
I'm guessing your computer was ok? Reason I ask, I had a very similar thing happen. 2 drops of water on my track pad. Seriously, 2 drops. The track pad started acting weird. Shut it down, unplugged it, let it dry. It worked fine. 2 days later, started jumping around again. Apple store tells me it is water damaged, and the track pad needs to be replaced. However, it is Apple's policy that any water damaged machine, they replace ALL components (logic board, etc.). $1200 for 2 drops of water!!! I'm furious. (So for the folks on this thread calling Jane paranoid, a couple drops of tap water can do a LOT of damage). My only other option is to take the machine to a 3rd party to replace the track pad, voiding the warranty. I find it unbelievable that 2 drops of water could cause that much damage. Any suggestions? Should I just replace the track pad, and roll the dice with a voided warranty? My other MBP I spilled about 20 oz. of water on when it was in a backpack. I let it dry out for a week, and everything has functioned fine.
I have no idea where to get one, but the 3rd party trackpad seems like a good decision. There is no point spending $1200 just to maintain the warranty.
