32S-II - is it possible to disassemble?

I hope it helps.
One thing to try before opening it. As theses models age, the foam strip that presses the keyboard's flexible circuit against the main circuit board deteriorates and causes them to lose contact. If you press down on area between the top row of keys and the display and hold pressure there *while* trying to use the non-functioning keys (including the ON key), they will often start working again as long as you hold down on that area.
