Hello- I purchased a 2011 13 Inch MacBook Air new and about two weeks ago spilled water on the keyboard. The computer immediately turned off. I freaked. I laid it upside down over a box fan with a towel for 3 days and didn't touch it. After that it would power on (only when connected to the power cord though) without issue. I don't have the money to have it repaired at Apple so I want to try to do it myself. Any idea if I need a battery replacement or the whole logic board?
