Changing
the
battery
Your
computer
has
a
special
type
of
memory
that
maintains
the
date,
time,
and
settings
for
built-in
features,
such
as
parallel-port
assignments
(configuration).
A
battery
keeps
this
information
active
when
you
turn
off
the
computer.
The
battery
normally
requires
no
charging
or
maintenance
throughout
its
life;
however,
no
battery
lasts
forever.
If
the
battery
fails,
the
date,
time,
and
configuration
information
(including
passwords)
are
lost.
An
error
message
is
displayed
when
you
turn
on
the
computer.
