Hi Joe,

Its been a while since I've used APM.  For ACPI, the percent typically
reported is the "percent of the last full charge" not the "percent of
the battery design capacity".  Initially, the two percents are about
equal.  But, over time, most batteries slowly loose the ability to hold
charge so the reported percentage is a fraction of an ever-decreasing
total.

Does that help explain what you're seeing?
