RE: HP 32S Repair
Hi,

The problem is that there is a rubber strip pushing the keyboard contacts against the PCB. This rubber deteriorates.

The best solution is to take the PCB off and replace the rubber under the keyboard contact strip (just under the screen). As you have already worked the twist tabs, you'll have to be careful loosening and refastening them.

See the middle of the page here where it says "HP48G Keyboard Connectors":

(the construction of the 32s is similar. Do not remove the metal keyboard plate, just lift up the connector strip to see the deteriorated rubber strip.)

I have successfully done that to several 48 models.
