Just wanted to share with others what happened to me the other evening. Basically I spilled a cup of espresso coffee (no sugar ) onto my mac book key board. I pulled the power plug, took out the battery and turned off and over my mac trying to eliminate the liquid. I left it infront of my dehumidifier machine for 48 hours. My husband turned it on last night and it work! I still have not plugged in the power source but will eventually. The keys were a little crunchy but that is the least of my problems. I am glad I read this forum because I probably would have had no hope to turn my computer on again..
