Same exact thing happened to me! Brand new hot starbucks green tea spilled all over my 4 month old MacBook Air mid-2013. I was devastated. Stupidly I tried to turn it on right after the spill and it turned on for a moment then shut off and wouldn't turn on again. I put the keyboard face down on paper towels and indirectly in front of a fan for a few days and it came back to life! I now have a keyboard spill guard of course...
