Chapter 2: Setting Up and Getting Started

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 3.

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.
