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

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.
