CAUTION: Safety Instructions
Use the following safety guidelines to help ensure your own personal safety and to help protect
your computer and working environment from potential damage.
General
• Do not attempt to service the computer yourself unless you are a trained service
technician. Always follow installation instructions closely.
• To help prevent electric shock, plug the computer and device power cables into properly
grounded electrical outlets. 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 avoid the potential hazard of electric shock, do not use your computer during an
electrical storm.
• To help avoid the potential hazard of electric shock, do not connect or disconnect any
cables or perform maintenance or reconfiguration of this product during an electrical
storm.
• If your computer includes a modem, the cable used with the modem should be
manufactured with a minimum wire size of 26 American wire gauge (AWG) and an
FCC-compliant RJ-11 modular plug.
• Before you clean your computer, disconnect the computer from the electrical outlet.
Clean your computer with a soft cloth dampened with water. Do not use liquid or aerosol
cleaners, which may contain flammable substances.
• To help avoid possible damage to the system board, wait 5 seconds after turning off the
computer before disconnecting a device from the computer.

System Information Guide 7
• 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.
• To help protect your computer from sudden, transient increases and decreases in
electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply
(UPS).
• Ensure that nothing rests on your computer’s cables and that the cables are not located
where they can be stepped on or tripped over.
• 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.
• Do not spill food or liquids on your computer. If the computer gets wet, consult the
User’s Guide.
CAUTION: Safety Instructions (continued)

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.
• 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, set the switch
for the voltage that most closely matches the AC power available in your location.
NOTICE: The voltage selection switch must be set to the 115-V position even though the AC power
available in Japan is 100 V.
Also, ensure that your monitor and attached devices are electrically rated to operate with
the AC power available in your location.
• 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.

System Information Guide 9
When Working Inside Your Computer
Before you open the computer cover, perform the following steps in the sequence indicated.
CAUTION: Do not attempt to service the computer yourself, except as explained in
your online Dell™ documentation or in instructions otherwise provided to you by
Dell. Always follow installation and service instructions closely.
NOTICE: To help avoid possible damage to the system board, wait 5 seconds after turning off the
computer before removing a component from the system board or disconnecting a device from the
computer.
1Perform an orderly computer shutdown using the operating system menu.
2Turn off your computer and any devices connected to the computer.
3Ground yourself by touching an unpainted metal surface on the chassis, such as the metal
around the card-slot openings at the back of the computer, before touching anything
inside your computer.
While you work, periodically touch an unpainted metal surface on the computer chassis
to dissipate any static electricity that might harm internal components.
4Disconnect your computer and devices, including the monitor, from their electrical
outlets. Also, disconnect any telephone or telecommunication lines from the computer.
Doing so reduces the potential for personal injury or shock.
In addition, take note of these safety guidelines when appropriate:
• When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the
cable itself. Some cables have a connector with locking tabs; if you are disconnecting this
type of cable, press in on the locking tabs before disconnecting the cable. As you pull
connectors apart, keep them evenly aligned to avoid bending any connector pins. Also,
before you connect a cable, ensure that both connectors are correctly oriented and
aligned.
