Safety Instructions
Use the following safety guidelines to help protect your computer from potential damage and to ensure your own personal safety.
When Using Your Computer
As you use your computer, observe the following safe-handling guidelines.
CAUTION: Do not operate your computer with any cover(s) (including computer covers, bezels, filler brackets, front-panel inserts, and so on)
removed.
l Your computer is equipped with one of the following:
¡ A fixed-voltage power supply — Computers with a fixed-voltage power supply do not have a voltage selection switch on the back panel and
operate at only one voltage (see the regulatory label on the outside of the computer for its operating voltage).
¡ An auto-sensing voltage circuit — Computers with an auto-sensing voltage circuit do not have a voltage selection switch on the back panel and
automatically detect the correct operating voltage.
¡ 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.
To help avoid damaging a computer with a manual voltage selection switch, ensure that the voltage selection switch is set to match the AC power
available at your location:
¡ 115 V/60 Hz in most of North and South America and some Far Eastern countries such as South Korea and Taiwan
¡ 100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
NOTE: The voltage selection switch must be set to the 115-V position even though the AC power available in Japan is 100 V.
¡ 230 V/50 Hz in some regions in the Caribbean and South America and most of Europe, the Middle East, and the Far East
Also, ensure that your monitor and attached devices are electrically rated to operate with the AC power available in your location.
l Before working inside the computer, unplug the computer to help prevent electric shock or system board damage. Certain system board components
continue to receive power any time the computer is connected to AC power.
l To avoid shorting out your computer when disconnecting a network cable, first unplug the cable from the network adapter on the back of your
computer, and then from the network jack. When reconnecting a network cable to your computer, first plug the cable into the network jack, and then
into the network adapter.
