Right now, I spilled coffee on the upper right of my 17 inch unibody machine. I turned it off immediately and put it upside down. Its now 3 hours past since that happened. I wonder how can I open the upper panel of the machine so that I can clean some traces of the coffee if it did reach some parts of the machine. Is there a step-by-step procedure in opening the upper panel without voiding the warranty? In addition, I hope the coffee didn't reach one of spill detectors.
