Use the following safety guidelines to protect yourself and your computer. For comfort and efficiency, observe the ergonomic guidelines provided in "Sitting Comfortably at Your Computer" in the Tell Me How help file.
CAUTION: Do not operate your computer with any cover(s) (including the computer cover, filler brackets, front-panel inserts, and so on) removed.
To help avoid damaging your computer, be sure 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 115V position
even though the AC supply in Japan is 100 V.
230 V/50 Hz in most of Europe, the Middle East, and the Far East
Also be sure that your monitor and attached devices are electrically rated to operate with the AC power available in your location.
To help prevent damage to your computer when disconnecting a network cable from your computer, first unplug the cable from the computer network connector and then from the network wall jack. When reconnecting a network cable to your computer, first plug the network cable into the network wall jack and then into the computer network connector.
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.
To help prevent electric shock, plug the computer and device power cables into properly grounded power sources. These cables are equipped with 3-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 3-wire cable with properly grounded plugs.
To help protect your computer from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or uninterruptable power supply.
Be sure that nothing rests on your computer 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, contact Dell.
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.
Before you open the computer cover, perform the following steps in the sequence indicated.
NOTICE: Do not attempt to service the computer yourself, except as
explained in this guide and elsewhere in Dell documentation. Always follow
installation and service instructions closely.
Turn off your computer and all devices.
Ground yourself by touching an unpainted metal surface at the back of
the computer before touching anything inside your computer.
While you work, periodically touch an unpainted metal surface on the computer to dissipate any static electricity that might harm internal components.
