I work in computer repair for a university, and we see students coming in all the time with liquid spills. We usually: 1) Disassemble the computer (ifixit.com is your friend here) 2) Clean the board with a non-conductive cleaner such as Electro Klene (http://www.criticalcleaning.com/CCContact.htm http://www.criticalcleaning.com/CCContact.htm) 3) Dry it off using compressed air and then let it air dry for a bit 4) Reassemble and cross fingers. We find this works about 1/2 the time.
