Re: HP97 Low Power warning--followup Message #8 Posted by Les Wright on 25 Dec 2006, 11:01 p.m., in response to message #5 by Les Wright
Nearly one week later and things are worse than they were before.
The bottom of the calc gets very warm when I try charging, but it has gotten to the point where even several hours of charging will not render the calculator usable, even on AC power. Only the low battery light is faintly lit, but there is no other display and the calculator can't be used.
I guess this is the question that I have--every other device that I have every had has a rechargeable battery pack can still be run off of AC power long after the battery pack fails to accept a charge. My old TI57 is the best example I can think of. But it looks like that in the HP97, an adequate battery pack is a key feature in completely the circuit even if one wants to just run the calculator off of AC power.
Can someone clarify this for me? I can accept that the battery pack is dead, or shorted, or whatever, as I think it's pretty old. What I can't figure out is why I can even use the calc on AC power, even if the battery is dead or not. I am worried there is something going on beyond just the battery.
Many thanks and Happy Holidays--
Les
