Watched a buddy spill coffee on the edge of his closed G3 Powerbook today. Looked like a superficial spill but, sure enough, the keyboard is now completely unresponsive. Mouse works, but not keyboard. The machine is running, but has since gone to sleep. Don't know how to wake the thing. I am a PC person and am basically Mac illiterate. Any suggestions for the guy other than "take it to the shop"?
