Checking the voltage selection
The power supply , a component built into your computer,
provides power to the system board, add-in cards, and
peripheral devices. The power supply’s voltage selection for
your location is typically set at the factory, but you can change
it to match the electrical service available in your usage area
(such as while in another country). Use the power selection
switch on the back of your computer to set the voltage to
115V or 230V.
To set the voltage selection switch:
1
Disconnect your computer’s power cable.
2
Use a tool such as an opened paper clip to slide the
voltage selection switch to the correct voltage position.
The switch is located on the back of your computer,
near the power cable connector. For the location, see
“Back” on page 8 .
Caution
If you set the voltage selection switch incorrectly, your system will be
damaged. Make sure this switch is set correctly for your location before turning
on your computer. In the United States, the utility power is supplied at a nominal
115 volts at 60 Hz. The power supply should always be set to this when your
computer is operating in the United States. In other areas of the world, such
as Europe, the utility power is supplied at 230 volts at 50 Hz. If your computer
is operating in an environment such as this, the voltage switch should be moved
to 230.
