Time Remaining is an estimate
based on notebook’s power
use at that moment. It,
therefore, depends on current
task and assumes power will
be used at that rate until
battery runs out. So if notebook
is currently using good deal
of power (such as when
reading CD or DVD), Time
Remaining likely shows less
time than actually remains.
