Your computer is equipped with either
an auto-sensing voltage selector or a
manual voltage selection switch.
Computers with an auto-sensing
voltage selector do not have a voltage
selection switch on the back panel and
can automatically detect the correct
operating voltage.
To help avoid damaging a computer
with a manual voltage selection switch,
set the switch for the voltage that most
closely matches the AC power available
in your location.
Also, ensure that your monitor and
attached devices are electrically rated to
operate with the AC power available in
your location.

switch must be set to the 115-V
position even though the AC
power available in Japan is 100 V.
