1. Turn off the computer.
2. Undock the computer if you have it docked.
3. Turn on the computer.
4. Press <F2> at the Dell BIOS splash screen to access the System Setup menu.
5. Select the following boot sequence:
•Boot First Device: Diskette Drive
•Boot Second Device: CDROM / DVDROM Drive
•Boot Third Device: Internal HDD
6. Insert the System Software CD into the CD-ROM drive.
7. Turn the computer off.
8. Turn the computer on.
The system restarts and automatically begins to run the Diagnostics.
9. When you have completed running Diagnostics, remove the Dell System Soft-
ware CD from the CD-ROM drive.
To change the boot sequence, repeat steps 1 through 5, customizing the boot
sequence to fit your needs. Restart your system.

•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 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
•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 into 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.

•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 com-
puter 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
liquid 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.

•If the touch pad becomes smudged from use, it can be cleaned using a soft,
clean cloth slightly dampened with water. Always turn off the computer before
cleaning the touch pad. To clean the touch pad, stroke the cloth gently across the
surface of the touch pad. Do not allow water from the cloth to seep between the
touch pad and the top cover of the computer.
•If your computer gets wet or is damaged, follow the procedures described in
“Troubleshooting Your Computer” in the User’s Guide. If, after following these
procedures, you confirm that your computer is not operating properly, contact
Dell Computer Corporation. (See “Getting Help” in the User’s Guide for the
appropriate telephone number.)

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 cur-
tains 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 [mm] [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.
•Keep your forearms horizontal with your wrists in a neutral, comfortable position
while using the keyboard, touch pad or external mouse.
•Always use the palmrest with the keyboard or touch pad. 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

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.
The following notice may appear throughout your Dell documentation to remind you
of these precautions:

Electromagnetic Interference (EMI) is any signal or emission, radiated in free space or
conducted along power or signal leads, that endangers the functioning of a radio navi-
gation or other safety service or seriously degrades, obstructs, or repeatedly
interrupts a licensed radio communications service. Radio communications services
include but are not limited to AM/FM commercial broadcast, television, cellular ser-
vices, radar, air-traffic control, pager, and Personal Communication Services (PCS).
These licensed services, along with unintentional radiators such as digital devices,
including computer systems, contribute to the electromagnetic environment.
Electromagnetic Compatibility (EMC) is the ability of items of electronic equipment to
function properly together in the electronic environment. While this computer system
has been designed and determined to be compliant with regulatory agency limits for
EMI, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause interference with radio communications services, which
can be determined by turning the equipment off and on, you are encouraged to try to
correct the interference by one or more of the following measures:
•Reorient the receiving antenna.
•Relocate the computer with respect to the receiver.
•Move the computer away from the receiver.
•Plug the computer into a different outlet so that the computer and the receiver
are on different branch circuits.
If necessary, consult a Technical Support representative of Dell Computer Corporation
or an experienced radio/television technician for additional suggestions. You may find
the FCC Interference Handbook, 1986, to be helpful. It is available from the U.S. Gov-
ernment Printing Office, Washington, DC 20402, Stock No. 004-000-00450-7 or on
the World Wide Web at http://www.fcc.gov/Bureaus/Compliance/WWW/
tvibook.html.
Dell computer systems are designed, tested, and classified for their intended electro-
magnetic environment. These electromagnetic environment classifications generally
refer to the following harmonized definitions:
•Class A is for business or industrial environments.
•Class B is for residential environments.
Information Technology Equipment (ITE), including peripherals, expansion cards, print-
ers, input/output (I/O) devices, monitors, and so on, that are integrated into or
connected to the system should match the electromagnetic environment classifica-
tion of the computer system.

Most Dell computer systems are classified by the Federal Communications
Commission (FCC) as Class B digital devices. However, the inclusion of certain
options can change the rating of some configurations to Class A. To determine which
classification applies to your computer system, examine all FCC registration labels
located on the bottom or back panel of your computer, on card-mounting brackets, and
on the cards themselves. If any one of the labels carries a Class A rating, your entire
system is considered to be a Class A digital device. If all labels carry an FCC Class B
rating as distinguished by either an FCC ID number or the FCC logo, ( ), your sys-
tem is considered to be a Class B digital device.
Once you have determined your system’s FCC classification, read the appropriate
FCC notice. Note that FCC regulations provide that changes or modifications not
expressly approved by Dell Computer Corporation could void your authority to operate
this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the follow-
ing two conditions:
•This device may not cause harmful interference.

and ringer equivalence number (REN) for your equipment. If requested, you must pro-
vide this information to the telephone company.
The REN is used to determine the quantity of devices that may be connected to the
telephone line. Excessive RENs on the telephone line may result in the devices not
ringing in response to an incoming call. In most areas, the sum of all the RENs on your
telephone line should be less than five to ensure proper service from the telephone
company. To be certain of the number of devices that you may connect to a line, as
determined by the total RENs, contact your local telephone company.
The registration jack Universal Service Order Code (USOC) used by this equipment is
RJ-11C. An FCC compliant telephone cord and modular plug is provided with this
equipment. This equipment is designed to be connected to the telephone network or
premises wiring using a compatible modular jack that is Part 68 compliant.
