Hey I'd like to add my two cents. I managed to spill about a half a glass of water on my Macbook near the air vent and the laptop went off. I was freaking out and tried to turn it on which it did but it again got shut down after a few minutes and then it refused to start. I know I did the biggest mistake but then I googled everywhere what should I be doing. With no hope I just reversed my macbook and kept it as it is air for two days occasionally exposing it to sunlight and miraculously it started working after two days. I am typing from my macbook write now.
