6. Make sure that the new power supply assembly is the correct replacement. Some power supply
assemblies automatically sense the voltage, some power supply assemblies are voltage specific, and
some power supply assemblies have a voltage-selection switch. If your power supply assembly has
a voltage-selection switch, make sure that you set the voltage-selection switch to match the voltage
available at your electrical outlet. If necessary, use a ballpoint pen to slide the voltage-selection switch
to the correct position.
• If the voltage supply range in your local country or region is 100–127 V ac, set the voltage-selection
switch to 115 V.
• If the voltage supply range in your local country or region is 200–240 V ac, set the voltage-selection
switch to 230 V.
