Safety Instructions
Use the following safety guidelines to help protect your computer from potential damage and to help ensure your own personal safety.
When Using Your Computer
As you use your computer, observe the following safety guidelines:
Do not attempt to service the computer yourself. Always follow installation
•
instructions closely.
Do not carry a battery pack in your pocket, purse, or other container where metal
•
objects (such as car keys) could short-circuit the battery terminals. The resulting
excessive current flow can cause extremely high temperatures and may result in
damage from burns.
Be sure that nothing rests on your AC adapter’s power cable and that the cable is
•
not located where it can be tripped over or stepped on.
Place the AC adapter in a ventilated area, such as a desk top or on the floor, when
•
you use it to run the computer or to charge the battery. Do not cover the AC
adapter with papers or other items that will reduce cooling; also, do not use the
AC adapter inside a carrying case.
Do not use your computer in a wet environment, for example, near a bath tub,
•
sink, or swimming pool or in a wet basement.
Do not push objects into air vents or openings of your computer. Doing so can
•
cause fire or electric shock by shorting out interior components.
Use only the AC adapter and batteries that are approved for use with this com-
•
puter as indicated in this document. Use of another type of battery pack or AC
adapter may risk fire or explosion.
Before you connect the computer to a power source, ensure that the voltage rat-
•
ing of the AC adapter matches that of the available power source:
— 115 volts (V)/60 hertz (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
— 230 V/50 Hz in most of Europe, the Middle East, and the Far East
v
To help prevent electric shock, plug the AC adapter 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.
If you use an extension cable with your AC adapter, ensure that the total ampere
•
rating of the products plugged in to the extension cable does not exceed the
ampere rating of the extension cable.
To remove power from the computer, turn it off, remove the battery pack, and dis-
•
connect the AC adapter from the electrical outlet.
If your computer includes an integrated or optional (PC Card) modem, disconnect
•
the modem cable during an electrical storm to avoid the remote risk of electric
shock from lightning via the telephone line.
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.
PC Cards may become very warm during normal operation. Use care when
•
removing PC Cards after their continuous operation.
Do not dispose of battery packs in a fire. They may explode. Check with local
•
authorities for disposal instructions.
When setting up the computer for work, place it on a level surface.
•
When traveling, do not check the computer as baggage. You can put your com-
•
puter through an X-ray security machine, but never put your computer through a
metal detector. If you have the computer checked by hand, be sure to have a
charged battery available in case you are asked to turn on the computer.
When traveling with the hard-disk drive removed from the computer, wrap the
•
drive in a nonconducting material, such as cloth or paper. If you have the drive
checked by hand, be ready to install the drive in the computer. You can put the
hard-disk drive through an X-ray security machine, but never put the drive through
a metal detector.
When traveling, do not place the computer in overhead storage compartments
•
where it could slide around. Do not drop your computer or subject it to other
mechanical shocks.
Protect your computer, battery, and hard-disk drive from environmental hazards
•
such as dirt, dust, food, liquids, temperature extremes, and overexposure to
sunlight.
When you move your computer between environments with very different tem-
•
perature and/or humidity ranges, condensation may form on or within the
computer. To avoid damaging the computer, allow sufficient time for the moisture
to evaporate before using the computer.
NOTICE: When taking the computer f ro m low-temperatur e cond iti ons
into a warmer environment or from high-temperature conditions into a
cooler environment, allow the computer to acclimate to room temperature before t ur n ing on power.
vi
When you disconnect a cable, pull on its connector or on its strain-relief loop, not
•
on the cable itself. As you pull out the connector, keep it evenly aligned to avoid
bending any connector pins. Also, before you connect a cable make sure both
connectors are correctly oriented and aligned.
Handle components with care. Hold a component such as a memory module by
•
its edges, not its pins.
When removing a memory module from the system board or disconnecting a
•
peripheral device from the computer, wait 5 seconds after turning off the computer before removing the memory module or disconnecting the device to help
avoid possible damage to the system board.
Before you clean your computer, turn it off, unplug it from its power source, and
•
remove the battery pack(s).
Clean your computer with a soft cloth dampened with water rather than with liq-
•
uid or aerosol cleaners.
Clean the display with a soft, clean cloth and commercial window cleaner that
•
does not contain wax or abrasives. Apply the cleaner to the cloth; then stroke the
cloth across the display in one direction, moving from the top of the display to the
bottom. If the display contains grease or some other contaminant, use isopropyl
alcohol instead of commercial window cleaner.hese chapters a
If your computer gets wet or is damaged, follow the procedures described in
•
Chapter 2, “Troubleshooting Your Computer.” If, after following these procedures, you confirm that your computer is not operating properly, contact Dell
Computer Corporation. (See Chapter 4, “Getting Help,” for the appropriate telephone number.)
Ergonomic Computing Habits
CAUTION: Improper or prolong ed keyboard use may result in injury.
CAUTION: Viewing the display or external monitor screen for extended
periods of time may result in eye strain.
For comfort and efficiency, observe the following ergonomic guidelines when setting
up and using your computer:
Position your computer directly in front of you as you work.
•
Adjust the tilt of the computer’s display, its contrast and/or brightness settings,
•
and the lighting around you (such as overhead lights, desk lamps, and the curtains or blinds on nearby windows) to minimize reflections and glare on the
display.
When using an external monitor with your computer, set the monitor at a com-
•
fortable viewing distance (usually 510 to 610 millimeters [20 to 24 inches] from
your eyes). Make sure the monitor screen is at eye level or slightly lower when
you are sitting in front of the monitor.
Use a chair that provides good lower-back support.
•
vii
Keep your forearms horizontal with your wrists in a neutral, comfortable position
•
while using the keyboard, trackball, touch pad, or external mouse.
Always use the palmrest with the keyboard, touch pad, or trackball. Leave space
•
to rest your hands when using an external mouse.
Let your upper arms hang naturally at your sides.
•
Sit erect with your feet resting on the floor and your thighs level.
•
When sitting, make sure the weight of your legs is on your feet and not on the
•
front of your chair seat. Adjust your chair’s height or use a footrest, if necessary,
to maintain proper posture.
Vary your work activities. Try to organize your work so that you do not have to
•
type for extended periods of time. When you stop typing, try to do things that
use both hands.

When Removing or Installing Memory
Modules
Before removing or installing memory modules, perform the following steps in the
sequence indicated.
NOTICE: The only time you should ever access the inside of your computer
is when you are installing memory modules.
NOTICE: W ait 5 seco nds after tu rning off the computer before disco nnecting
a peripheral device or re m o vin g a memory module to help preve n t possible damage to the system board.
1.Turn off your computer and any attached peripherals.
2.Disconnect your computer and peripherals from electrical outlets to reduce the
potential for personal injury or shock. Also, disconnect any telephone or telecommunication lines from the computer.
3.Remove the main battery from the Battery Bay and, if necessary, the secondary
battery from the media bay.
4.Ground yourself by touching the unpainted metal surface of the I/O panel on the
back of the computer.
While you work, periodically touch the I/O panel to dissipate any static electricity
that might harm internal components.
Protecting Against Electrostatic Discharge
Static electricity can harm electronic components inside your computer. To prevent
static damage, discharge static electricity from your body before you touch any of
your computer’s electronic components, such as a memory module. You can do so by
touching an unpainted metal surface on the computer’s I/O panel.
As you continue to work inside the computer, periodically touch an I/O connector to
remove any static charge your body may have accumulated.
You can also take the following steps to prevent damage from electrostatic discharge
(ESD):
When unpacking a static-sensitive component from its shipping carton, do not
•
remove the component from the antistatic packing material until you are ready to
install the component. Just before unwrapping the antistatic packaging, be sure
to discharge static electricity from your body.
When transporting a sensitive component, first place it in an antistatic container
•
or packaging.
Handle all sensitive components in a static-safe area. If possible, use antistatic
•
floor pads and workbench pads.
