This is odd.  I once (yes, *only* once!) had a memory lost.  Being the
cautious sort, I wanted to drain my hp28s completely of all power so
that it word come up completely in default state (an extreme cold
boot).  To do this, I removed the batteries overnight.

The next morning, I put them back in.  Surprise!  Everything was still
there!  Obviously the batteries had not been out long enough.  So I
tried 24 hours.  Everything was still there.  Finally, I left them out
for 48 hours.  When I replaced the batteries, everything was
(finally!) cleared.

Maybe it takes a while to charge up the internal backup battery?  Also
you said you found a defective third battery.  Maybe this kept the
internal battery from being fully recharged.
