Use the following safety guidelines to help protect your computer system from potential damage and to ensure your own personal
safety.
When Using Your Computer System
As you use your computer system, observe the following safety guidelines.
WARNING: Do not operate your computer system with any cover(s) (including computer covers, bezels, filler
brackets, front-panel inserts, and so on) removed.
To help avoid damaging your computer, be sure the voltage selection switch on the power supply is set to match the AC
power available at your location:
– 115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries such as Japan,
South Korea, and Taiwan
– 230 V/50 Hz in most of Europe, the Middle East, and the Far East
Also be sure your monitor and attached peripherals are electrically rated to operate with the AC power available in your location.
Before working inside the computer, unplug the system 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.
To help avoid possible damage to the system board, wait 5 seconds after turning off the system before disconnecting a
device from the computer.
To help prevent electric shock, plug the computer and peripheral power cables into properly grounded power sources. These
cables are equipped with 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.
To help protect your computer system from sudden, transient increases and decreases in electrical power, use a surge
suppressor, line conditioner, or un-interruptible power supply (UPS).
Be sure nothing rests on your computer system’s cables and that the cables are not located where they can be stepped on
or tripped over.
Do not spill food or liquids on your computer. If the computer gets wet, consult your Diagnostics and Troubleshooting Guide.
Do not push any objects into the openings of your computer. Doing so can cause fire or electric shock by shorting out
interior components.
Keep your computer away from radiators and heat sources. Also, do not block cooling vents. Avoid placing loose papers
underneath your computer; do not place your computer in a closed-in wall unit or on a bed, sofa, or rug.
Ergonomic Computing Habits
WARNING: Improper or prolonged keyboard use may result in injury.
For comfort and efficiency, observe the following ergonomic guidelines when setting up and using your computer system:
Position your system so that the monitor and keyboard are directly in front of you as you work. Special shelves are available
