spilt beer on IBM T40

Archived from groups: comp.sys.laptops (More info?)

Fortunately, it was just a small amount.. It shutdown by itself... and
i basically turned it upside down for hours without trying anything..
finally, cleanup with dry towels etc.. and it works... Yeah, it
works!!! Now i am getting greedy.. some keys on the top right are a
little sticky.. still work well but you don't get the same "typing
experience".. has to be because of the beer.. its not the same crisp
key press anymore.. Any ideas on what to do?? can i take the keyboard
apart and clean it somehow. don't want to mess up other things
though.. please advise..

thanks

Most of those keyboards are plastic-welded together and can't be taken
apart. However, some are held together with screws (lots of them). If
you have the screw-type, you are golden, if not, you are likely screwed.

In most of those keyboards, the active elements are printed conductive
traces on two pieces of plastic (mylar), with a 3rd piece sandwiched
between them. The 3rd piece has a hole at each key, allowing the
outside two to touch if pressure is applied.

If you get ANY liquid into the plastic sandwich, the keyboard is
probably ruined unless it can be taken apart and cleaned.

The "feel" issue is likely in the pluger assembly that "presses on" the
3-layer mylar sandwich. This is not part of the active circuitry, it's
just a mechanical device to "hit" the mylar sandwhich. The problem is
figuring out how to clean it (a simple water rinse would probably do the
job) without getting water into the active "mylar sandwhich", because if
you do, it will probably be ruined. Unfortunately, I don't see any
low-risk process for doing that.

His problem isn't going to be removing the keyboard, it's going to be
taking the keyboard apart.

I had try many times to clean keyboards after a spill and never could i make
them work properly after. The best thing for you is to try to find a cheap
keyboard in ebay. Is going to be a bit dificult becouse the model of laptop
that you got ibm tp t40 is not very comun.
