Verify that the voltage selection switch is set correctly for your location.
Your computer has a manual voltage selection switch. Computers with a voltage selection
switch on the back panel must be manually set to operate at the correct operating voltage.
NOTICE: To help avoid damaging a computer with a manual voltage selection switch, set the switch for
the voltage that most closely matches the AC power available in your location.
NOTE: Before you install any devices or software that did not ship with your computer, read the
documentation that came with the device or software, or contact the vendor to verify that the device or
software is compatible with your computer and operating system.
