I "Pepsi Syndromed" my Office KB, took it apart and cleaned it all up,
works again just fine. It did take a lot of time, but I was lost w/o it,
I hated the Wireless Optical Desktop Elite I replaced it with (a very fine
unit really, but I was just too addicted to the Office KB and my Trackball
Explorer, both of which were nuked by the spill. BTW, the trackball was
WAY harder to take apart and clean - talk about finicky alignment of
parts, geesh! Disassmebled and reassembled at least a dozen times to get
it just right, w/o any buttons catching/scraping or misfiring w/o tactile
feedback. Now I know why they don't make it anymore, this thing must have
taken very patient assemblers on the production line, and major quality
assurance steps. But, I diverge...).
The three layers of plastic go in rather logically, w/ the keys on top
(duh), and the bottom layer has the tiny holes in it to align w/ the
little positioning pins from below, and it has the white/silver tracings;
the last is the middle layer which is basically just an insulator w/ holes
at each key-dimple, no tracings. It's really very simple (ie, cheap), but
ANY residual liquid/sticky-stuff ANYWHERE can cause an electrical
sneak-path and keep it from working. clean it thouroughly, w/ distilled
water and a lintless cloth, dry completely. Be sure the connectors are
clean/dry too. The keys shd never stick, if they do there's gunk under the
little "collapsing dimple" or the plastic key unit itself has gunk in it -
that part (the white top w/ the keycaps) you can submerge to get clean,
all the keycaps are retained well.
Be careful w/ the rubber dimples! they are glued down at their edges only
slightly, and can easily be scrapped off accidentially. If you do that
you can glue them back in place, use super glue AND JUST A TINY DAB at the
edges - NONE should get into the center area or you're SOL. Use a
toothpick to dab it on, don't apply a drop directly, it'll definately seep
under if you do that.
Note: I may have been lucky, I did not get any liquid underneath any of
the rubber dimples - it flowed between the plastic sheets, but the dimples
were relatively clean. If you've got dried-on gunk under them you may be
screwed, that's gonna be hard to clean w/o perhaps damaging the dimples.
Inspect the top layer carefully from below, look at each dimple and clean
out carefully w/ a q-tip ONLY if necessary; do NOT rub off any of that
black coating in the dome of the dimple - that's the carbon contact,
degrade it and it'll stop working forever.
Good Luck!
