His comments were completely correct. When I disassembled the keyboard per his instructions, I found that there was an oily residue on the printed circuit board on the contact points where the bad key posts press the board. After cleaning the circuit board, and reassembling the keys worked just fine. This could not have been fixed by removing the keycaps from the outside. I have had more than my share of experience (and success) repairing ADM3a keyboards from the outside, but this just won't work on a T1000. It is a bit painful having to remove dozens of little screws to get at the circuit board, but that is really the only choice. -- Ken Mandelberg | km@mathcs.emory.edu PREFERRED Emory University | {decvax,gatech}!emory!km UUCP Dept of Math and CS | km@emory.bitnet NON-DOMAIN BITNET Atlanta, GA 30322 | Phone: (404) 727-7963
