I walked home from the library in the rain. When I got home, I dried my laptop off, but the keyboard was completely spazzing - it wouldn't type, then it'd type letter I hadn't told it to, etc. This went on for a few hours, and I was resigned to going to a shop to get it fixed. My keyboard had gotten a little wet before with no problem, so I was a little confused, but figured moisture was the culprit. I started playing chess on it, since that doesn't require a keyboard, and I pressed 'x' to exit, since I forgot my keyboard wasn't working. It worked! Did the water mess it up? And did it start working suddenly because the water suddenly evaporated? Or was something else going on?
