HP 31E buttons not responding Message #1 Posted by Adam Vaughn on 8 June 2011, 5:43 p.m.
Hello everyone. I recently picked up a HP 31E calculator. At first, everything seemed fine. However, it seems to have developed an issue with the 8, 5, and 2 keys. They seem to have become highly intermittent, taking many button presses to work. When they do work, there seems to be a far higher amount of 'key bounce' than with any of the other keys, causing lots of repeating. At first, I thought the keys might just be in need of cleaning, but the fact that they're in the same vertical row makes me wonder (though the decimal key seems unaffected). Any ideas on how I might be able to solve this issue? Thanks in advance!
