Care of cleaning.... Neither did I use spray nor get any liquid into the keys.. The unit was powered off with the batteries removed. I used a damp cloth with detergent on it, being carefull not to get it too wet. There was a lot of debris around the keys which I thought I got off without falling inside the keyboard.
Today, I used canned air to try to blow between the keys (not much help). I also turned the keyboard upside down and knocked it against my soft belly several times.. Wow, did a lot of sxxt come out. So I suppose I have some debris lodged inside against the keyboard membrane.
Any ideas other than a new keyboard?
You do seem to have tried to avoid the obvious problems. Are the debries there because you normally work in a homely environment, perhaps not quite so pristine as a perfectionists might expect.
I honestly cannot see other than a replacement, Gone2sea, and a gentle prod in the direction of keeping your housekeeping up to scratch in future.
Excuse me....... "Seventy One".......
