HP41CV Help/Advice
Message #1 Posted by Steve Gosselin on 27 May 2003, 11:40 p.m.

Hi all. I have a HP41CV that I purchased what seems to be many years ago. Some 8 years ago its simply stopped working - it won't turn on using either the ac adaptor or replacable batteries. The calculator was well cared for and prior to that it never gave any indication of problems. It has sat in my desk since. Can anyone tell me what might be the problem and where or how I might get it repaired?

Hi, Steve;

let's first identify which model you have. Please, look at the LCD window and compare what you see to the image below.

This image belongs to the HP Museum (this site).

In both cases, the best starting point is cleaning batteries contacts, the ones in the calculator. If you see they are O.K, chances are you have a small battery leakage and that the residal leak got between the kayboard and the battery connectors assembly. In this case, it's necessary to open the calcualtor. Do you need advice for this?

If so, let us know so we can continue.

Best regards.
