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

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

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

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.
