Do
not
bend
or
modify
the
plug.
If
the
plug
is
damaged,
contact
the
manufacturer
to
obtain
a
replacement.
Some
products
are
equipped
with
a
three-pronged
plug.
This
plug
fits
only
into
a
grounded
electrical
outlet.
This
is
a
safety
feature.
Do
not
defeat
this
safety
feature
by
trying
to
insert
it
into
a
non-grounded
outlet.
If
you
cannot
insert
the
plug
into
the
outlet,
contact
an
electrician
for
an
approved
outlet
adapter
or
to
replace
the
outlet
with
one
that
enables
this
safety
feature.
Never
overload
an
electrical
outlet.
The
overall
system
load
should
not
exceed
80
percent
of
the
branch
circuit
rating.
Consult
an
electrician
for
more
information
if
you
have
questions
about
power
loads
and
branch
circuit
ratings.
Be
sure
that
the
power
outlet
you
are
using
is
properly
wired,
easily
accessible,
and
located
close
to
the
equipment.
Do
not
fully
extend
power
cords
in
a
way
that
will
stress
the
cords.
Connect
and
disconnect
the
equipment
from
the
electrical
outlet
carefully
Batteries
Many
IBM
personal
computers
contain
a
non-rechargeable
coin
cell
battery
to
provide
power
to
the
system
clock.
In
addition
many
mobile
products
such
as
Thinkpad
notebook
PCs
utilize
a
rechargeable
battery
pack
to
provide
system
power
when
in
portable
mode.
Batteries
supplied
by
IBM
for
use
with
your
product
have
been
tested
for
compatibility
and
should
only
be
replaced
with
IBM
approved
parts.
Never
attempt
to
open
or
service
any
battery.
Do
not
crush,
puncture,
or
incinerate
batteries
or
short
circuit
the
metal
contacts.
Do
not
expose
the
battery
to
water
or
other
liquids.
Only
recharge
the
battery
pack
strictly
according
to
instructions
included
in
the
product
documentation.
Battery
abuse
or
mishandling
can
cause
the
battery
to
overheat,
which
can
cause
gasses
or
flame
to
“vent”
from
the
battery
pack
or
coin
cell.
If
your
battery
is
damaged,
or
if
you
notice
any
discharge
from
your
battery
or
the
buildup
of
foreign
materials
on
the
battery
leads,
stop
using
the
battery
and
obtain
a
replacement
from
the
battery
manufacturer.
Batteries
can
degrade
when
they
are
left
unused
for
long
periods
of
time.
For
some
rechargeable
batteries
(particularly
Lithium
Ion
batteries),
leaving
a
battery
unused
in
a
discharged
state
could
increase
the
risk
of
a
battery
short
circuit,
which
could
shorten
the
life
of
the
battery
and
can
also
pose
a
safety
hazard.
Do
not
let
rechargeable
Lithium-Ion
batteries
completely
discharge
or
store
these
batteries
in
a
discharged
state.
