I'd remove the logicboard, soak it in 99% alcohol, dry it after a few hours in the oven (wrap in alumium foil and use something around 100 degree centigrade). After that have good look with a magnifier for any residant stains and clean the manually. Assemble and keep your fingers crossed.

I rescued a few liquid victims that way.

If the DC-in board was fried then as long as the battery had power it'd boot up, which is a likely possibility, batteries are some of the first things to go after a liquid spill, the first thing you should do when you spill is yank the battery out- unfortunately the new MacBooks require a little more time than the turn of a quarter :(.

So if you can test with another battery that'd be a good idea, otherwise I'm sorry to say it's the logic board, which 2/5 times is the problem after a liquid spill.

turn of a quarter would have been much quicker than going out to find a tri-wing!

will try another battery and post again. your reply is greatly appreciated. :)
