I have an HP 32SII on which the keys on the right hand-most column are 'difficult', either they have to be pressed very hard or I have to press the top left and bottom right corners of the calculator onto the desk to get a normal key response. Unfortunately I don't have a third arm/hand so this option is a bit tricky.
Does anyone have any cures for my calculator malaise, can I open it to clean contacts? Immerse it in a cleaning solvent? Anything?
Constructive ideas welcome. The 32SII is a great calculator and dear to my heart, there is no sensible replacement for it.
