I just acquired an HP41CX complete with a dead rechargable battery packs. I pluged the unit in and pressed the ON button, but nothing happened. Is my calculator dead? Is there some secret handshake to bring it back to life?
When the battery pack is plugged in to the wall charger, the measured voltage on the battery pack is about 5.1 volts. This makes me think that even with the dead battery, the wall charger should be powering the calculator. Since it is not, I presume the calculator is dead.
One last hope would be to buy 4 N-sized alkaline batteries and see what happens. Is that worth a try, or would I be throwing my money away?
It would be a shame if the thing is dead. It came with a soft brown case, a printer, two card readers,MATH 1, SURVEYING 1, and XMEMORY.
The calculator also came with a black sliding clamp with a spring on it. It says "PRIMA TOOLING PTY. LTD. MELB on it. It is 9 cm wide and 7.5 cm high. Evidently it is a stand to hold the calculator up at a 30 degree angle.
