Voltage switch Before turning on your computer, make sure that this switch is in
the correct position for the correct power available. The switch is
preset at the factory with the correct voltage for your area.
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. See “Checking the
voltage selection” on page 11.
