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 the computer cover, filler brackets, front-panel inserts, and so on)
removed or opened.
Your computer is equipped with one of the following:
l
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, be sure that the voltage selection switch is set to match the AC power
l
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 115V position even though the AC supply 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
¡
NOTE:
Fixed-voltage power supplies and auto-select power supplies do not require a voltage selection switch. Your power supply may not have
this switch. Check the regulatory label on the outside of the computer for your power supply type.
Also be sure that your monitor and attached devices are electrically rated to operate with the AC power available in your location.
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,
l
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.
To help avoid possible damage to the system board, wait 5 seconds after turning off the computer before disconnecting or connecting a non-USB device
l
from the computer.
To help prevent electric shock, plug the computer and device power cables into properly grounded power sources. These cables are equipped with
l
three-prong plugs to help ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use an
extension cable, use a three-wire cable with properly grounded plugs.
