My original submission on my problem with system time losing time relative
to reference provided some informative responses.  I was using Atom Time to
update so I investigated information on the CMOS battery, and found out it
is  a "Dallas DS 12887 real time clock and CMOS battery integrated into the
RTC chip" and sells for $19.95.

So I sent an email to Packard Bell asking how to correct the problem and
received this terse reply:

"The battery is not replaceable."

Not completely believing I would be so lucky as to have an irreplaceable
battery, but interpreting the terseness of the PB response as being the
extent of the advice I will obtain from them, I turn to anyone with
experience to explain why the CMOS battery is not replaceable.  It can't be
that efficient, or otherwise I wouldn't be loosing time. Is it so embedded
in the circuit that if it does malfunction, one discards the motherboard or
a large component?  Is this an unusual problem?

TIA
