Guys, my G15 v2 seems to have a problem with the spacebar button. It's no longer tactile. I have to press it all the way down for it to register - and half the time, the button would be stuck there. It would not spring up again until I lightly rap the connecting wrist rest with my wrist or I firmly press down the button again.

Warranty ended years ago. I wonder if there's anyone here that experienced the same problem before? Any fix?
