The
rate
at
which
you
use
battery
power
determines
how
long
you
can
use
the
battery
of
your
computer
between
charges.
As
each
computer
user
has
different
habits
and
needs,
it
is
difficult
to
predict
how
long
a
battery
charge
will
last.
There
are
two
main
factors:
v
The
amount
of
energy
stored
in
the
battery
when
you
begin
to
work.
v
The
way
you
use
your
computer:
for
example,
how
often
you
access
the
hard
disk
drive
and
how
bright
you
make
the
computer
display.
