Voltage-selection switch Some computers are equipped with a voltage-selection switch located near the power-cord connection point on the computer. If your computer has a voltage-selection switch, ensure that you set the switch to match the voltage available at your electrical outlet. Setting the voltage-selection switch incorrectly can cause permanent damage to the computer. If your computer does not have a voltage-selection switch, your computer is designed to operate only at the voltage provided in the country or region where the computer was originally purchased. If you relocate your computer to another country, be aware of the following: v If your computer does not have a voltage-selection switch, do not connect the computer to an electrical outlet until you have verified that the voltage provided is the same as it was in the country or region where the computer was originally purchased. v If your computer has a voltage selection switch, do not connect the computer to an electrical outlet until you have verified that the voltage-selection switch is set to match the voltage provided in that country or region. If you are not sure of the voltage provided at your electrical outlet, contact your local electric company or refer to official Web sites or other literature for travelers to the country or region where you are located. Extension cords and related devices Ensure that extension cords, surge protectors, uninterruptible power supplies, and power strips that you use are rated to handle the electrical requirements of the product. Never overload these devices. If power strips are used, the load should not exceed the power strip input rating. Consult an electrician for more information if you have questions about power loads, power requirements, and input ratings. Plugs and outlets If a receptacle (power outlet) that you intend to use with your computer equipment appears to be damaged or corroded, do not use the outlet until it is replaced by a qualified electrician. Do not bend or modify the plug. If the plug is damaged, contact the manufacturer to obtain a replacement. Do not share an electrical outlet with other home or commercial appliances that draw large amounts of electricity; otherwise, unstable voltage might damage your computer, data, or attached devices. 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. Important safety information ix

Voltage-selection
switch
Some
computers
are
equipped
with
a
voltage-selection
switch
located
near
the
power-cord
connection
point
on
the
computer.
If
your
computer
has
a
voltage-selection
switch,
ensure
that
you
set
the
switch
to
match
the
voltage
available
at
your
electrical
outlet.
Setting
the
voltage-selection
switch
incorrectly
can
cause
permanent
damage
to
the
computer.
If
your
computer
does
not
have
a
voltage-selection
switch,
your
computer
is
designed
to
operate
only
at
the
voltage
provided
in
the
country
or
region
where
the
computer
was
originally
purchased.
If
you
relocate
your
computer
to
another
country,
be
aware
of
the
following:
v
If
your
computer
does
not
have
a
voltage-selection
switch,
do
not
connect
the
computer
to
an
electrical
outlet
until
you
have
verified
that
the
voltage
provided
is
the
same
as
it
was
in
the
country
or
region
where
the
computer
was
originally
purchased.
v
If
your
computer
has
a
voltage
selection
switch,
do
not
connect
the
computer
to
an
electrical
outlet
until
you
have
verified
that
the
voltage-selection
switch
is
set
to
match
the
voltage
provided
in
that
country
or
region.
If
you
are
not
sure
of
the
voltage
provided
at
your
electrical
outlet,
contact
your
local
electric
company
or
refer
to
official
Web
sites
or
other
literature
for
travelers
to
the
country
or
region
where
you
are
located.
Extension
cords
and
related
devices
Ensure
that
extension
cords,
surge
protectors,
uninterruptible
power
supplies,
and
power
strips
that
you
use
are
rated
to
handle
the
electrical
requirements
of
the
product.
Never
overload
these
devices.
If
power
strips
are
used,
the
load
should
not
exceed
the
power
strip
input
rating.
Consult
an
electrician
for
more
information
if
you
have
questions
about
power
loads,
power
requirements,
and
input
ratings.
Plugs
and
outlets
If
a
receptacle
(power
outlet)
that
you
intend
to
use
with
your
computer
equipment
appears
to
be
damaged
or
corroded,
do
not
use
the
outlet
until
it
is
replaced
by
a
qualified
electrician.
Do
not
bend
or
modify
the
plug.
If
the
plug
is
damaged,
contact
the
manufacturer
to
obtain
a
replacement.
Do
not
share
an
electrical
outlet
with
other
home
or
commercial
appliances
that
draw
large
amounts
of
electricity;
otherwise,
unstable
voltage
might
damage
your
computer,
data,
or
attached
devices.
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.
