Checking the voltage selection

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.
A power supply is integrated into your computer to provide power to the system board, add-in
cards, and peripheral devices. The voltage selection for your location is typically set at the factory.
Use the power selection switch on the back of your computer to set the power supply to 115V
or 230V. To verify that your system has the correct setting for your environment, check the
voltage selection switch.

CHAPTER 2: Using Your Computer
Caution
If you set the voltage selection switch incorrectly, your system will be damaged.
Use a tool such as an opened paper clip to slide the voltage selection switch to the correct
voltage position. For the location of the switch, see your setup poster or hardware
reference.
Connect the cables to your computer according to the setup poster.
Turn on your computer.
Important
Your computer has a built-in variable speed fan. In addition, your computer
uses a powerful processor which produces heat. Both the system fan and processor
can run at different speeds at times to ensure proper system cooling. You may
notice an increase in the fan noise when the fan is running at high speed and a
decrease in the fan noise when it switches to normal speed.
If you are starting your computer for the first time, follow the on-screen instructions to
set up your computer.
Attach and turn on any peripheral devices, such as printers or scanners, and see the
documentation that came with the device for setup instructions.
