Well since nobody else is going to respond, I might as well fill you in on what worked for me. As it turns out, the button assembly on the G74 has a rubberized cover on top of the actual button, which one can remove by edging around the entire button with a credit card. I took both button covers off and threw them in the dish washer, then threw them back on after applying some plastic glue to the insides. Works like new, no dis-assembly required.
