My HP 91 just quit on me after 25 years of service. Can a bad battery cause such a shut down? If so, does anyone know where to obtain a new battery pack? If not, does anyone know who might repair such a machine?

Battery Packs can be rebuilt at batteries Plus or other battery stores for not too much money. Do not operate the calc without the batteries in place (the printer will break).
