I could be wring but I don't think its a cap issue if the mouse is working as well as a few keys.

Do you have another ADB KB you can try and use to see if that one works? I have a feeling the failure after the recap is just a coincidence.

Keep us posted.

Is it always the same keys? Then likely the keyboard will be the issue..

Probably a broken trace, one only is enough and can have this kind of behavior.

Agree with @bibilit ... may help if you identify specifically which keys are not working, if a broken trace a pattern will emerge.

Hi guys & gals,

Finally had some time to work on this. I had the keyboard out if the case since I was going to recap it my self (haven't done). Once I reassembled it all the keys work now.

EDIT:
Uggh... 😩
I spoke too soon.

-Reds don't work. Strange cause I was having issues with "R" but it's working now.
-Yellow unable to test.
-Green circle (top right) caps. Could these 30+ y/o things cause an issue?
-No issues with Number Pad.

Thx 🤠

EDIT
E and W are now working but have to press a bit hard on key. I swapped out serial cable but no change. 🤔

Wait a tick - ALL of the keys worked right after you reassembled everything? I wonder if you have some persistent corrosion along the chain somewhere; perhaps a liberal application of contact cleaner at all connectors is in order?
