A full cup no less, all over my MBP 13. It was bound to happen - I drink so much of the damned stuff. Dog was on my lap at the time - poor little bastard got pitched to the floor as I picked up the MBP, turned it upside down, unplugged the power and quickly did a forced shutdown. (Glad it wasn't a child ). Dried it out with a blow dryer. Seems to work fine. I hope over time it the innards don't corrode. Thank god it was coffee black, no sugar. At least I held off on AppleCare as I'm sure the liquid sensor is tripped. Somebody please tell me you've done this a hundred times with no ill effects.
