Question about HP 20s Calculator
When I changed the batteries the / * - + buttons on the right hand side stopped working.
Does anyone know of a way to repair it or of a repair person in London that could help me?
If the calculator has locked up you should perform a reset.
If it continues to malfunction, it will need to be repaired. One repair shop in Pennsylvania, USA has a website at http://www.fixthatcalc.com Here is the link . You should contact them.
Hope it helps.
Thank you for rating the solution.
