Re: HP-65 battery problems Message #3 Posted by Matthew Riehl on 3 June 2000, 9:34 a.m., in response to message #1 by Brian Keller
If the problem is the contact plate at the charger plug-in point, you can aslo check this by jumping across the two outside charger posts with a wire. This would duplicate the function of the gold contact. If that is the problem, the cleaning should do.
Alternately, I had a similar problem with my HP-65. When I bought it the battery pack was bad, so I rebuilt it. Therefore I knew that it was good. Yet when I put it in, the calculator wouldn't run off of it. I found that if the battery pack was in to far it didn't work. I determined this by putting in the battery pack without the battery door, and then turning it right side up on my hand. As I lifted up slightly on the calculator it started working normally off of the battery pack.
The final solution was just a strip of paper, the length battery compartment, folded up until it was 1/8" wide by 1/16" deep. Once this was underneath the top of the battery pack, the door could be put on and it has worked normally ever since. Hope this helps.
