I'd try just taking the keyboard off and seeing if washing it off will help. If that doesn't do it, get a new one.
Last night my wife spilt maybe 1/4 cup of beer on my brand new Toshiba Satellite P500
Wiped up what I could and shut it down for the evening.
Next morning some keys will not work.. computer starts up fine, no noises, burning etc. Just the keys are a little wonky.
Should I just remove and rinse the keyboard? or replace it entirely?
I don't care if this voids the warranty as I only have the (1)yr manufacture warranty on it.
Thanks for the help, Eric
