This
section
provides
instructions
on
how
to
replace
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.
Refer
to
the
“Lithium
battery
notice”
in
the
ThinkCentre
Safety
and
Warranty
Guide
for
information
about
replacing
and
disposing
of
the
battery.
