When I first saw the thread title, I thought you meant digital piano keyboards: a bit heavier to turn upside down! But no, you don't wanna spill liquids on those either. I always hold my breath if a well-meaning bandmate chooses to pass me a glass of water (or something stronger) over the piano!

I did have one laptop wino disaster: full glass of white wine over it: despite doing all the things you're supposed to do, including prolonged drying out (it and me!) the keyboard never functioned properly again (nor did I?). Fortunately our very good friend up the road established that the computer itself was OK by plugging in via USB extra keyboard, and got me a replacement for £15. Learning curve -and-a-half as it was a couple of days before a festival I was organising, and there was lost of crucial stuff on that laptop!
