I spilt coffee on my i book last night I immeadiately pulled out the power supply and took out the battery. I turned it upside down and called a 'pc' guy I know. I'm currently living in a remote country location and I can't get my lap top to an authorized Mac service centre. So, I took my Mac to the 'pc' guy, he opened it up and cleaned it out. He used some sort of gel that was in a syringe, he told me it was motherboard fluid cleaner? He proceeded to clean the motherboard with a tooth brush...wierd! Anyway...as luck would have it 2 hours later, the thing actually worked! He told me he has to keep it overnight and let it dry out. I was just wondering if the guy has done any further damage to my Mac (although I did the original damage!) Also, how much should I pay him for his services?
