Question about Panasonic Toughbook 48 Notebook

Keyboard Circuit Faulty?

So i recently aquired a CF-48 from my grandfather because of a keyboard issue, anyways it smelled like cat pee so i pulled the keyboard out rinsed it with luke warm water and allowed it to thoroughly dry for 4 days.
still having issues the following keys dont work: i o p l ; \ enter, backspace, right shift

Ive pulled the keyboard apart and inspected the contact pad. thinking that the computer is possibly disabling keys that remain depressed on start up i flexed it much like you would flex a stack of paper before putting it into a printer.
while all the other keys operate more smoothly now, the keys originally out still dont work. when it was appart i did not see any damaged traces whatsoever. could it be the keyboard just gave up or is it something more sinister within the computer itself?

Re: Keyboard Circuit Faulty?

Since all of the failing keys are on the right hand side, I'd try a short (maybe 15 minutes) soak in warm soapy water of the right hand 1/2 of the keyboard. While it is soaking, every few minutes try depressing the failing keys several time each. Follow this with a good rinse with warm water and a good drying. A hair drier will help to speed up the process. If that doesn't work, you'll probably need to find a replacement keyboard.
