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
product.
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.
Contact
the
Customer
Support
Center
for
further
guidance.
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
Customer
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
following
conditions,
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
Customer
Support
Center
for
further
guidance.
• Power cords, plugs, power adapters, extension cords, surge protectors, or power supplies that are
cracked, broken, or damaged.
• Signs of overheating, smoke, sparks, or fire.
• Damage to a battery (such as cracks, dents, or creases), discharge from a battery, or a buildup of foreign
substances on the battery.
• A cracking, hissing or popping sound, or strong odor that comes from the product.
• Signs that liquid has been spilled or an object has fallen onto the computer product, the power cord or

• The computer product, power cord, or power adapter has been exposed to water.
• The product has been dropped or damaged in any way.
• The product does not operate normally when you follow the operating instructions.
Note:
If you notice these conditions with a product (such as an extension cord) that is not manufactured for
or by Lenovo, stop using that product until you can contact the product manufacturer for further instructions,
or until you get a suitable replacement.
Service and upgrades
Do not attempt to service a product yourself unless instructed to do so by the Customer Support Center or
your documentation. Only use a Service Provider who is approved to repair your particular product.
Note:
Some computer parts can be upgraded or replaced by the customer. Upgrades typically are
referred to as options. Replacement parts approved for customer installation are referred to as Customer
Replaceable Units, or CRUs. Lenovo provides documentation with instructions when it is appropriate for
customers to install options or replace CRUs. You must closely follow all instructions when installing or
replacing parts. Before you remove the covers from a product equipped with a power cord, always make
sure that the power is turned off and that the product is unplugged from any power source. If you have
any questions or concerns, contact the Customer Support Center.
Although there are no moving parts in your computer after the power cord has been disconnected, the
following warnings are required for your safety.
