v Damage to a battery (such as cracks, dents, creases), discharge from a battery, or a buildup of foreign substances on the battery. v A cracking, hissing or popping sound, or strong odor that comes from the product. v Signs that liquid has been spilled or an object has fallen onto the computer product, the power cord or power adapter. v The computer product, the power cord or power adapter has been exposed to water. v The product has been dropped or damaged in any way. v The product does not operate normally when you follow the operating instructions. Note: If you notice these conditions with a non-IBM product (such as an extension cord), stop using that product until you can contact the product manufacturer for further instructions, or until you get a suitable replacement. General safety guidelines Always observe the following precautions to reduce the risk of injury and property damage. Service Do not attempt to service a product yourself unless instructed to do so by the IBM Support Center. Use only an IBM authorized service provider who is approved to repair your particular product. Note: Some parts can be upgraded or replaced by the customer. These parts are referred to as Customer Replaceable Units, or CRUs. IBM expressly identifies CRUs as such, and provides documentation with instructions when it is appropriate for customers to replace those parts. You must closely follow all instructions when performing such replacements. Always make sure that the power is turned off and that the product is unplugged from any power source before you attempt the replacement. If you have any questions or concerns, contact the IBM Support Center. Power cords and power adapters Use only the power cords and power adapters supplied by the product manufacturer. Never wrap a power cord around the power adapter or other object. Doing so can stress the cord in ways that can cause the cord to fray, crack or crimp. This can present a safety hazard. Always route power cords so that they will not be walked on, tripped over, or pinched by objects. Protect the cord and power adapters from liquids. For instance, do not leave your cord or power adapter near sinks, tubs, toilets, or on floors that are cleaned with liquid cleansers. Liquids can cause a short circuit, particularly if the cord or power adapter has been stressed by misuse. Liquids can also cause gradual corrosion of the power cord terminals and/or the connector terminals on the adapter which can eventually result in overheating. vi User Guide

General
safety
guidelines
Always
observe
the
following
precautions
to
reduce
the
risk
of
injury
and
property
damage.
Service
Do
not
attempt
to
service
a
product
yourself
unless
instructed
to
do
so
by
the
IBM
Support
Center.
Use
only
an
IBM
authorized
service
provider
who
is
approved
to
repair
your
particular
product.
Note:
Some
parts
can
be
upgraded
or
replaced
by
the
customer.
These
parts
are
referred
to
as
Customer
Replaceable
Units,
or
CRUs.
IBM
expressly
identifies
CRUs
as
such,
and
provides
documentation
with
instructions
when
it
is
appropriate
for
customers
to
replace
those
parts.
You
must
closely
follow
all
instructions
when
performing
such
replacements.
Always
make
sure
that
the
power
is
turned
off
and
that
the
product
is
unplugged
from
any
power
source
before
you
attempt
the
replacement.
If
you
have
any
questions
or
concerns,
contact
the
IBM
Support
Center.
Power
cords
and
power
adapters
Use
only
the
power
cords
and
power
adapters
supplied
by
the
product
manufacturer.
Never
wrap
a
power
cord
around
the
power
adapter
or
other
object.
Doing
so
can
stress
the
cord
in
ways
that
can
cause
the
cord
to
fray,
crack
or
crimp.
This
can
present
a
safety
hazard.
Always
route
power
cords
so
that
they
will
not
be
walked
on,
tripped
over,
or
pinched
by
objects.
Protect
the
cord
and
power
adapters
from
liquids.
For
instance,
do
not
leave
your
cord
or
power
adapter
near
sinks,
tubs,
toilets,
or
on
floors
that
are
cleaned
with
liquid
cleansers.
Liquids
can
cause
a
short
circuit,
particularly
if
the
cord
or
power
adapter
has
been
stressed
by
misuse.
Liquids
can
also
cause
gradual
corrosion
of
the
power
cord
terminals
and/or
the
connector
terminals
on
the
adapter
which
can
eventually
result
in
overheating.
