The Time Remaining is an
estimate based on how
quickly the computer is using
power at the moment. It
therefore depends on the
current task, and assumes
that power will be used at the
same rate until the battery
runs out. So, for example, if
the computer is performing a
task requiring a good deal of
power (such as reading from
a CD or DVD), the value will
probably show too little time
remaining.
