scheme.
When using applications with
automatic save feature (such
as MS Word), extend save
time or disable to reduce
hard disk access and power
usage.

Battery capacity often
decreases after a year or
more.
Battery indicator is
inaccurate.
Time Remaining is an
estimate based on how much
power the notebook is using
at that moment. It therefore
depends on the current task,
and assumes power will be
used at the same rate until
the battery runs out. So, for
example, if the notebook 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.
