Keyboard Problem Latitude CPi R400GT

The keyboard on Latitude CPi R400GT Bios ver A09 acts like it has stuck key. External keyboard works properly. None of the keys seem to me stuck by feel. I can lift the keyboard out of the chassis and supporting it with strips of wood above the palmrest and it works fine. I can flex the ribbon cable and not get any problems I can also flex the keyboard and it still functions properly, until I drop it back into the chassis at which point I get all kinds of garbage. I have cleaned the ribbon cable end and the socket it seats into.

I noticed that different metal bits of the chassis touch the underside of the keyboard. I put tape over them, but that did not stop the behavior. I took a piece of wire and connected it between the bottom of the keyboard and the metal bits of the chassis and palmrest (not the mobo) which induced bad behavior.

I get the behavior running different OS's and also running Knoppix from the CD Drive w/HDD removed.

Several weeks prior to the keyboard problem, the receptacle that the charger plugs into went south, and I could not charge the battery. I placed the laptop into it's docking station and am able to plug the charger into it and the battery gets charged. I am thinking that the problem is the mobo, and not the keyboard.
