So over a week ago, I was walking back from my job around 2am. I stopped to print some stuff off, and noticed my lower back was wet. Upon further investigation, a water bottle broke open in my backpack soaking through an econ textbook, stack of articles, newspaper and a neoprene macbook case. I opened the case, and water got into my macbook aluminum. I didn't turn it on, opened it up, and let it air out for a few days. The computer works fine nowadays, and the only damage was to the battery, which needs replaced. I didn't buy Apple Care when I bought my macbook in October. With the water damage, is it even worth buying Apple Care at this point as the water damage stickers are all 'activated' in my Macbook, thus voiding the warranty right?
