HP41C calculator



#4

Hi, All!

I hold an HP41C calculator.

After I hadn't worked with it for too years,
I tried to operate it, but only the start beep
works with 4 fresh batteries.

Best regards,
Tal

Hi;

There are several reasons for this to happen. One of the major ones is "dirty" data. Sometimes, simply oppening the calc and short-circuiting both capacitors inside it is enough. One other reason is physical dirty, now in the batteries/IO assembly. This leads us to a question: do you know how to open the calculator? Are you ready to try?

Let us know. (if you want to have a look first, go here just to know how to open it.)

cheers.

Thanks for your help.
Regards,
Tal
