®
 
personal

Follow
 
and

all

included
 
with

IBM
 
computer.
 
The
 
information
 
in
 
this
 
document
 
does
 
not
 
alter

Customer
 
safety
 
is
 
important
 
to
 
IBM.
 
Our
 
products
 
are
 
developed
 
to
 
be
 
safe
 
and
 
effective.
 
However,
 
personal
 
computers
 
are
 
electronic
 
devices.
 
Power
 
cords,
 
power
 
adapters,
 
and
 
other
 
features
 
can
 
create
 
potential
 
safety
 
risks
 
that
 
can
 
result
 
in
 
physical
 
injury
 
or
 
property
 
damage,
 
especially
 
if
 
misused.
 
To
 
reduce
 
these
 
risks,
 
follow
 
the
 
instructions
 
included
 
with
 
your
 
product,
 
observe
 
all
 
warnings
 
on
 
the
 
product
 
and
 
in
 
the
 
operating
 
instructions,
 
and
 
review
 
the
 
information
 
included
 
in
 
this
 
document
 
carefully.
 
By
 
carefully
 
following
 
the
 
information
 
contained
 
in
 
this
 
document
 
and
 
provided
 
with
 
your
 
product,
 
you
 
can
 
help
 
protect
 
yourself
 
from
 
hazards
 
and
 
create
 
a
 
safer
 
computer
 
work
 
environment.
 
Note:
 
This
 
information
 
includes
 
references
 
to
 
power
 
adapters
 
and
 
batteries.
 
In
 
addition
 
to
 
mobile
 
personal
 
computers,
 
IBM
 
ships
 
some
 
products
 
(such
 
as
 
speakers
 
or
 
monitors)
 
with
 
external
 
power
 
adapters.
 
If
 
you
 
have
 
such
 
a
 
product,
 
this
 
information
 
applies
 
to
 
your
 
product.
 
In
 
addition,
 
your
 
computer
 
product
 
may
 
contain
 
a
 
coin-sized
 
internal
 
battery
 
that
 
provides
 
power
 
to
 
your
 
system
 
clock
 
even
 
when
 
the
 
machine
 
is
 
unplugged,
 
so
 
the
 
battery
 
safety
 
information
 
applies
 
to
 
all
 
computers.
 
Conditions
 
that
 
require
 
immediate
 
action
 
Products
 
can
 
become
 
damaged
 
due
 
to
 
misuse
 
or
 
neglect.
 
Some
 
product
 
damage
 
is
 
serious
 
enough
 
that
 
the
 
product
 
should
 
not
 
be
 
used
 
again
 
until
 
it
 
has
 
been
 
inspected
 
and,
 
if
 
necessary,
 
repaired
 
by
 
an
 
authorized
 
servicer.
 
As
 
with
 
any
 
electronic
 
device,
 
pay
 
close
 
attention
 
to
 
the
 
product
 
when
 
it
 
is
 
turned
 
on.
 
On
 
very
 
rare
 
occasions,
 
you
 
might
 
notice
 
an
 
odor
 
or
 
see
 
a
 
puff
 
of
 
smoke
 
or
 
sparks
 
vent
 
from
 
your
 
machine.
 
Or
 
you
 
might
 
hear
 
sounds
 
like
 
popping,
 
cracking
 
or
 
hissing.
 
These
 
conditions
 
might
 
merely
 
mean
 
that
 
an
 
internal
 
electronic
 
component
 
has
 
failed
 
in
 
a
 
safe
 
and
 
controlled
 
manner.
 
Or,
 
they
 
might
 
indicate
 
a
 
potential
 
safety
 
issue.
 
However,
 
do
 
not
 
take
 
risks
 
or
 
attempt
 
to
 
diagnose
 
the
 
situation
 
yourself.
 
Frequently
 
inspect
 
your
 
computer
 
and
 
its
 
components
 
for
 
damage
 
or
 
wear
 
or
 
signs
 
of
 
danger.
 
If
 
you
 
have
 
any
 
question
 
about
 
the
 
condition
 
of
 
a
 
component,
 
do
 
not
 
use
 
the
 
product.
 
Contact
 
the
 
IBM
 
Support
 
Center
 
or
 
the
 
product
 
manufacturer
 
for
 
instructions
 
on
 
how
 
to
 
inspect
 
the
 
product
 
and
 
have
 
it
 
repaired,
 
if
 
necessary.
 
In
 
the
 
unlikely
 
event
 
that
 
you
 
notice
 
any
 
of
 
the
 
conditions
 
listed
 
below,
 
or
 
if
 
you
 
have
 
any
 
safety
 
concerns
 
with
 
your
 
product,
 
stop
 
using
 
the
 
product
 
and
 
unplug
 
it
 
from
 
the
 
power
 
source
 
and
 
telecommunication
 
lines
 
until
 
you
 
can
 
speak
 
to
 
the
 
IBM
 
Support
 
Center
 
for
 
further
 
guidance.
