I have loved this calculator for about 2 years then it finally needed some batteries....Since then I have had nothing but problems. Every now and then when I turn it on it will say memory lost...sometimes it is sometimes it isn't. It sure is a hassle because it takes a long time to enter a bunch of equations only to have the machine crash. Sometimes the battery light will just come on and stay on until I hit the shift key. I have talked to other people with the older 28s' and they seemed to agree that something is screwed up with the machines...I mean I have bought 3 sets of batteries in the last 6 months, they all can't be bad so soon. Well...what can I do? any suggestions? ******************************************************************************

I called HP about a problem of constant memory failures and occasionally the machine shutting itself off while I was using it. The customer rep said that for the earlier HP28s (and c i assume) the battery compartment was designed for a specific size of the N type battery and since that design the battery manufacturers have changed their N type battery size by a fraction. The batteries in your calculator have room to move around a little causing bad contact. HP told me to mail the calculator to their repair center listed in the back of the manual and it would be fixed free of charge. Its been a week now and I'm anxiously waiting...

This is probably obvious, but I have had problems in the past with dirty contacts on batteries and connectors. Even brand new batteries have given me funny, intermittent problems until I cleaned the contacts with a pencil eraser. Try it, don't cost nuthin'. -- Bill McFadden Tektronix, Inc. P.O.
