Dry for 24 hours in an oven on low (< 140 F) heat. I have had some success by imersing the machine in an ultrasonic cleaner. Even if you cut them all loose, getting the keyboard back with good feel is highly unlikely. It is heat staked down with a zillion melted plastic rivets. Once you open the machine, repairing the keyboard is just about impossible. These machines were never meant to be opened or repaired. Message #8 Posted by David Smith on, 5:27 p.m., One past without problems but the other still have some problems, needs a litle bi uo adjustment I guess. "press and hold the yx key and press the ON/C key" etc. In response to message #6 by Eric EdwardsĪs I guess with all featured calculators at the HP-museum Message #7 Posted by Eric Edwards on, 8:21 p.m., Keyboard and CPU? I could not find anything on the HP-32S article itself, maybe it is somewhere else? Eric I have never used the HP-32s and have no manual. Message #6 Posted by Eric Edwards on, 7:11 a.m., They're definitely worth the effort to keep 'em running. The 32S is easily my favorite HP model for daily use. If the top end doesn't stay together satisfactorily, you may use a soldering iron to melt the posts and holes together again. I dropped one once and one side separated slightly, but the halves didn't come completely apart. The friction bond seems to stand up to most normal use. (Don't cut the mushroomed ends off or shorten them - just trim their widths so they squeeze back into the holes in the metal backing plate.) I just trim the mushroomed ends of the four lower heat stakes so they're just slightly larger than the posts themselves, and pop the sides back together again. They're easily made to stick back together, if you haven't drilled the upper heat stakes too deeply. I've taken apart just about every Pioneer model I own.

Actually I had two HP-32S with excatly the same problem and they both were fixed the same way :) But how do I put the casing back together again? Preferably so it can be openened without too much difficulties in the future! Any ideas? Eric (Couldn't have done it without his help, thanks Paul.)Īfter a little bit of fiddling taking out the PCB I found the error. Thank you all! I took it apart as described by Paul Brogger.

Does anybody know what could be wrong with the keys? Do you think it would be fixable when/if I can open the calculator. I see no screw holes like the Hp 12C etc. Since I have never opened a calculator like this before I was hoping that somebody here had done it and knew how to do it without damaging the calculator. I have a HP-32s that has all the rightmost keys not working. Message #1 Posted by Eric Edwards on, 8:36 a.m. HP-32S: How do I open the casing without damaging the calculator?
