Faulty Key Kicks Out Two Letters Instead of One

[leolion]

My Dell Latitude D610 keyboard's 'w' key always puts out 'wr'. When I key 'wo' quickly, it puts out 'wror', keying 'we' gets 'wrer'. Other than this 'w' key, it is okay. I don't think it is the keyboard driver or any software dealing with it. I replaced the keyboard with a good functioning one from another D610 and did not have this problem.

So the keyboard is defective, replacing the 'w' key with a new one doesn't make a difference. Can someone verify that I am correct in coming to this conclusion? Has anyone ever encountered this type of key issue? I'm curious.

Your answer is much appreciated. Thanks.

Probably a short in the wiring beneath the keyboard.

Hi,

It looks like you've taken the same troubleshooting steps that I would have taken, and it sounds like the physical keyboard (or connection between that and the MoBo) was borked...

Replacing the button/key wouldn't make any difference, as all it does is press down on a sensor pad; whatever happens to be pressing that pad down, will be pressing it down...if the communication from that board to the OS (via the cable to the MoBo, etc) then it won't output what your input is expecting...

Another step that I would have taken before swapping (onboard/built-in) keyboards over would have been to plug a USB keyboard in, see whether that made any difference...which, it most likely, would have done...

Have you spilled something in it? Similar happened to my HP after I spilled some water on it. Remove the keyboard and run it under hot water. Make sure to let it dry thoroughly. A hair dryer can help on low heat setting (so as not to warp any of the rubber or plastic). It may have a plastic sheet on the bottom which can be cut off to help dry, though you'll never want to spill anything in the keyboard again as it may get into the internals next time.
