The worst thing happened to me. I bought a used mid 2010 MacBook Pro and when I came home to clean it, I accidentally spilled a little bit of windex onto the trackpad. The computer was off, and I took as much liquid out with a paper towel by pressing down on the trackpad and getting all the corners. Did that a few times. My regrets are that I didn't think of blow drying it and I started using the computer about 15 minutes after it happened. It's worked fine but I am worried it will be problematic in the future. Is there a fix to it if it does break? And what would be the cost?
