Note:
Some
parts
can
be
upgraded
or
replaced
by
the
customer.
These
parts
are
referred
to
as
Customer
Replaceable
Units,
or
CRUs.
Lenovo
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
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
proper
UL
certification.
Danger
Hazardous
moving
parts.
Keep
fingers
and
other
body
parts
away.
Attention:
Before
replacing
any
CRUs,
turn
off
the
computer
and
wait
three
to
five
minutes
to
let
the
computer
cool
before
opening
the
cover.
Power
cords
and
power
adapters
Use
only
the
power
cords
and
power
adapters
supplied
by
the
product
manufacturer.
The
power
cord
and
power
adapter
are
intended
for
use
with
this
product
only.
They
should
never
be
used
with
any
other
product.
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.
