Your computer is equipped with a manual voltage-selection

voltage-selection switch, set the switch for the voltage that
most closely matches the AC power available in your
location.
NOTICE: In Japan, the voltage selection switch must be
set to the 115-V position.
Also, ensure that your monitor and attached devices are
electrically rated to operate with the AC power available in
your location.
