This sounds like either corroded battery contacts or a corroded connection between the battery contacts and the PCB due to battery leakage. The HP-71B is fairly easy to take apart (see here: https://www.hpmuseum.org/disasm.htm). You probably can do it yourself, there is no big risk of breaking anything.

Good luck
