The AC adapter converts AC power to the DC power required by the computer. You can connect the AC adapter
with your computer turned either on or off.
CAUTION: The AC adapter works with electrical outlets worldwide. However, power connectors and power
strips vary among countries. Using an incompatible cable or improperly connecting the cable to the power strip
or electrical outlet may cause fire or equipment damage.
NOTICE: When you disconnect the AC adapter cable from the computer, grasp the connector, not the cable itself,
and pull firmly but gently to avoid damaging the cable. When you wrap the AC adapter cable, ensure that you follow
the angle of the connector on the AC adapter to avoid damaging the cable.

Using a Battery
Battery Performance
NOTE: For information about the Dell warranty for your computer, see the Product Information Guide or separate
paper warranty document that shipped with your computer.
For optimal computer performance and to help preserve BIOS settings, operate your Dell™ portable
computer with the main battery installed at all times. One battery is supplied as standard equipment in
the battery bay.
NOTE: Because the battery may not be fully charged, use the AC adapter to connect your new computer to an
electrical outlet the first time you use the computer. For best results, operate the computer with the AC adapter
until the battery is fully charged. To view battery charge status, access the Control Panel→ Power Options, and
then click the Power Meter tab.
NOTE: Battery operating time (the time the battery can hold a charge) decreases over time. Depending on how
often the battery is used and the conditions under which it is used, you may need to purchase a new battery during
the life of your computer.
Battery operating time varies depending on operating conditions. You can install an optional second
battery in the media bay to significantly increase operating time.
Operating time is significantly reduced when you perform operations including, but not limited to, the
following:
•
Using optical drives
•
Using wireless communications devices, PC Cards, ExpressCards, media memory cards, or USB
devices
•
Using high-brightness display settings, 3D screen savers, or other power-intensive programs such as 3D
games
•
Running the computer in maximum performance mode (see "Configuring Power Management
Settings" on page 31).
NOTE: It is recommended that you connect your computer to an electrical outlet when writing to a CD or DVD.
You can check the battery charge before you insert the battery into the computer (see "Checking the
Battery Charge" on page 28). You can also set power management options to alert you when the battery
charge is low (see "Configuring Power Management Settings" on page 31).
CAUTION: Using an incompatible battery may increase the risk of fire or explosion. Replace the battery only
with a compatible battery purchased from Dell. The lithium ion battery is designed to work with your Dell
computer. Do not use a battery from other computers with your computer.
CAUTION: Do not dispose of batteries with household waste. When your battery no longer holds a charge, call
your local waste disposal or environmental agency for advice on disposing of a lithium-ion battery. See "Battery
Disposal" in the Product Information Guide.

CAUTION: Misuse of the battery may increase the risk of fire or chemical burn. Do not puncture, incinerate,
disassemble, or expose the battery to temperatures above 65°C (149°F). Keep the battery away from children.
Handle damaged or leaking batteries with extreme care. Damaged batteries may leak and cause personal injury
or equipment damage.
Checking the Battery Charge
The Dell QuickSet Battery Meter, the Microsoft Windows Power Meter window and
icon, the
battery charge gauge and health gauge, and the low-battery warning provide information on the battery
charge.
Dell™ QuickSet Battery Meter
If Dell QuickSet is installed, press  to display the QuickSet Battery Meter. The Battery
Meter displays status, battery health, charge level, and charge completion time for the battery in your
computer.
For more information about QuickSet, right-click the
icon in the taskbar, and click Help.
Microsoft® Windows® Power Meter
The Windows Power Meter indicates the remaining battery charge. To check the Power Meter, doubleclick the
icon on the taskbar.
If the computer is connected to an electrical outlet, a
icon appears.
Charge Gauge
By either pressing once or pressing and holding the status button on the charge gauge on the battery, you
can check:
•
Battery charge (check by pressing and releasing the status button)
•
Battery health (check by pressing and holding the status button)
The battery operating time is largely determined by the number of times it is charged. After hundreds of
charge and discharge cycles, batteries lose some charge capacity—or battery health. That is, a battery can
show a status of "charged" but maintain a reduced charge capacity (health).
Check the Battery Charge
To check the battery charge, press and release the status button on the battery charge gauge to illuminate
the charge-level lights. Each light represents approximately 20 percent of the total battery charge. For
example, if the battery has 80 percent of its charge remaining, four of the lights are on. If no lights
appear, the battery has no charge.

NOTE: You can check battery health in one of two ways: by using the charge gauge on the battery as described
below and by using the Battery Meter in Dell QuickSet. For information about QuickSet, right-click the
icon in
the taskbar, and click Help.
To check the battery health using the charge gauge, press and hold the status button on the battery
charge gauge for at least 3 seconds. If no lights appear, the battery is in good condition, and more than 80
percent of its original charge capacity remains. Each light represents incremental degradation. If five
lights appear, less than 60 percent of the charge capacity remains, and you should consider replacing the
battery. See "Specifications" on page 119 for more information about the battery operating time.
Low-Battery Warning
NOTICE: To avoid losing or corrupting data, save your work immediately after a low-battery warning. Then
connect the computer to an electrical outlet. If the battery runs completely out of power, hibernate mode begins
automatically.
By default, a pop-up window warns you when the battery charge is approximately 90 percent depleted.
You can change the settings for the battery alarms in QuickSet or the Power Options Properties window.
See "Configuring Power Management Settings" on page 31 for information about accessing QuickSet or
the Power Options Properties window.
Conserving Battery Power
Perform the following actions to conserve battery power:
•
Connect the computer to an electrical outlet when possible because battery life is largely determined
by the number of times the battery is used and recharged.
•
Place the computer in standby mode or hibernate mode when you leave the computer unattended for
long periods of time (see "Power Management Modes" on page 29).
•
Use the Power Management Wizard to select options to optimize your computer’s power usage. These
options can also be set to change when you press the power button, close the display, or press
.
NOTE: See "Power Management Modes" on page 29 for more information on conserving battery power.
Power Management Modes
Standby Mode
Standby mode conserves power by turning off the display and the hard drive after a predetermined
period of inactivity (a time-out). When the computer exits standby mode, it returns to the same
operating state it was in before entering standby mode.
NOTICE: If your computer loses AC and battery power while in standby mode, it may lose data.
To enter standby mode:

Charging the Battery
NOTE: With Dell™ ExpressCharge™, when the computer is turned off, the AC adapter charges a completely
discharged battery to 80 percent in about 1 hour and to 100 percent in approximately 2 hours. Charge time is longer
with the computer turned on. You can leave the battery in the computer for as long as you like. The battery’s internal
circuitry prevents the battery from overcharging.
When you connect the computer to an electrical outlet or install a battery while the computer is
connected to an electrical outlet, the computer checks the battery charge and temperature. If necessary,
the AC adapter then charges the battery and maintains the battery charge.
If the battery is hot from being used in your computer or being in a hot environment, the battery may
not charge when you connect the computer to an electrical outlet.
The battery is too hot to start charging if the
light flashes alternately green and orange. Disconnect
the computer from the electrical outlet and allow the computer and the battery to cool to room
temperature. Then connect the computer to an electrical outlet to continue charging the battery.
For more information about resolving problems with a battery, see "Power Problems" on page 79.
Replacing the Battery
CAUTION: Before performing these procedures, turn off the computer, disconnect the AC adapter from the
electrical outlet and the computer, disconnect the modem from the wall connector and computer, and remove any
other external cables from the computer.
NOTICE: You must remove all external cables from the computer to avoid possible connector damage.
CAUTION: Using an incompatible battery may increase the risk of fire or explosion. Replace the battery only
with a compatible battery purchased from Dell. The battery is designed to work with your Dell™ computer. Do not
use a battery from other computers with your computer.

Wireless Local Area Network (WLAN)
A WLAN is a series of interconnected computers that communicate with each other over the air waves
rather than through a network cable connected to each computer. In a WLAN, a radio communications
device called an access point or wireless router connects network computers and provides Internet, or
network, access. The access point or wireless router and the wireless network card in the computer
communicate by broadcasting data from their antennas over the air waves.
What You Need to Establish a WLAN Connection
Before you can set up a WLAN, you need:
•
High-speed (broadband) Internet access (such as cable or DSL)
•
A broadband modem that is connected and working
•
A wireless router or access point
•
A wireless network card for each computer that you want to connect to your WLAN
•
A network cable with the network (RJ-45) connector
Checking Your Wireless Network Card
Depending on what you selected when you purchased your computer, the computer has a variety of
configurations. To confirm that your computer has a wireless network card and to determine the type of
card, use one of the following:

About Smart Cards
Smart cards are portable credit-card shaped devices with internal integrated circuits. The top surface
of the smart card usually contains an embedded processor under the gold contact pad. The
combination of the small size and integrated circuits make smart cards valuable tools for security,
data storage, and special programs. Using smart cards can improve system security by combining
something a user has (the smart card) with something only the user should know (a PIN) to provide
more secure user-authentication than passwords alone.

Passwords
NOTE: Passwords are disabled when you receive your computer.
A primary (or system) password, an administrator password, and a hard drive password all prevent
unauthorized access to your computer in different ways. The following table identifies types and features
of passwords available on your computer.
Type of Password
Features
Primary/System
• Protects the computer from unauthorized access
Administrator
• Gives system administrators or service technicians
access to computers for repair or reconfiguration
• Allows you to restrict access to system setup in the same
way a primary password restricts access to the computer
• Can be used instead of the primary password
Hard drive
• Helps protect the data on your hard drive or external
hard drive (if one is being used) from unauthorized
access
NOTE: Some hard drives do not support hard drive passwords.
NOTICE: Passwords provide a high level of security for data in your computer or hard drive. However, they are not
foolproof. If you require more security, obtain and use additional forms of protection, such as smart cards, data
encryption programs, or PC Cards with encryption features.
If you forget any of your passwords, contact your system administrator or contact Dell (see "Contacting
Dell" on page 130). For your protection, Dell support staff will ask you for proof of your identity to ensure
that only an authorized person can use the computer.
NOTE: Dell OpenManage™ Client Instrumentation version 7.3 or later must be installed on the computer for system
administrators to assign passwords remotely.
Using a Primary/System Password
The primary (system) password allows you to protect the computer from unauthorized access.
Access User Accounts from the Control Panel to create user accounts and add or change passwords. After
assigning a primary password, you must enter it each time you turn on your computer.
If you do not enter a password within 2 minutes, the computer returns to its previous operating state.
NOTICE: If you disable the administrator password, the primary password is also disabled.
If you have assigned an administrator password, you can use it instead of the primary password. The
computer does not specifically prompt you for the administrator password.

Using an Administrator Password
The administrator password is designed to give system administrators or service technicians access to
computers for repair or reconfiguration. The administrators or technicians can assign identical
administrator passwords to groups of computers, allowing you to assign a unique primary password.
To set or change administrator passwords, access User Accounts from the Control Panel.
When you set an administrator password, the Configure Setup option becomes available in the system
setup program. The Configure Setup option allows you to restrict access to system setup in the same way
that a primary password restricts access to the computer.
The administrator password can be used instead of the primary password. Whenever you are prompted
to enter the primary password, you can enter the administrator password.
NOTICE: If you disable the administrator password, the primary password is also disabled.
NOTE: The administrator password provides access to the computer, but it does not provide access to the hard
drive when a hard drive password is assigned.
If you forget the primary password and do not have an administrator password assigned, or if you have
both a primary and an administrator password assigned but forget them both, contact your system
administrator or contact Dell (see "Contacting Dell" on page 130).
Using a Hard Drive Password
The hard drive password helps protect the data on your hard drive from unauthorized access. You can
also assign a password for an external hard drive (if one is being used) that can be the same as or different
from the password for the primary hard drive.
After assigning a hard drive password, you must enter it each time you turn on the computer and each
time you restore the computer to normal operation from standby mode.
If the hard drive password is enabled, you must enter it each time you turn on the computer: A message
appears asking for the hard drive password.
To continue, enter your password (with no more than eight characters) and press .
If you do not enter a password within 2 minutes, the computer returns to its previous operating state.
If you enter the wrong password, a message tells you that the password is invalid. Press  to try
again.
If you do not enter the correct password in three attempts, the computer tries to start from another
bootable device if the Boot First Device option in the system setup program is set to allow start-up from
another device. If the Boot First Device option is not set to allow the computer to start from another
device, the computer returns to the operating state it was in when you turned it on.
If the hard drive password, the external hard-drive password, and the primary password are the same, the
computer prompts you only for the primary password. If the hard drive password is different from the
primary password, the computer prompts you for both. Two different passwords provide greater security.
NOTE: The administrator password provides access to the computer, but it does not provide access to the hard
drive when a hard drive password is assigned.

operation is not possible on battery power alone. Ensure that the AC adapter is connected to your
computer when the computer is docked to the Dell D/Dock.
Docking While the Computer Is Running
If a computer is connected to the Dell D/Dock or Dell D/Port while the computer is running, presence of
the docking device is ignored until the AC adapter is connected to the computer.
AC Power Loss While the Computer Is Docked
If a computer loses AC power while docked to the Dell D/Dock or Dell D/Port, the computer
immediately goes into low-performance mode.

System Setup Program
Overview
NOTE: Your operating system may automatically configure most of the options available in the system setup
program, thus overriding options that you set through the system setup program. (An exception is the External Hot
Key option, which you can disable or enable only through the system setup program.) For more information on
configuring features for your operating system, access the Help and Support Center (see "Windows Help and
Support Center" on page 11).
You can use the system setup program as follows to:
•
Set or change user-selectable features—for example, your computer password
•
Verify information about the computer's current configuration, such as the amount of system memory
After you set up the computer, run the system setup program to familiarize yourself with your system
configuration information and optional settings. You may want to write down the information for future
reference.
The system setup screens display the current setup information and settings for your computer, such as:
•
System configuration
•
Boot order
•
Boot (start-up) configuration and docking-device configuration settings
•
Basic device-configuration settings
•
System security and hard-drive password settings
NOTICE: Unless you are an expert computer user or are directed to do so by Dell technical support, do not change
the system setup settings. Certain changes might make your computer work incorrectly.
Viewing the System Setup Screens
1 Turn on (or restart) your computer.
2 When the DELL™ logo appears, press  immediately. If you wait too long and the Windows logo
appears, continue to wait until you see the Windows desktop. Then shut down your computer and try

Commonly Used Settings
Certain settings require that you reboot the computer for new settings to take effect.
Changing the Boot Sequence
The boot sequence tells the computer where to look to find the software needed to start the operating
system. You can control the boot sequence and enable/disable devices using the Boot Sequence page,
which is located in the System category.
NOTE: To change the boot sequence on a one-time-only basis, see "Performing a One-Time Boot" on page 86.
The Boot Sequence page displays a general list of the bootable devices that may be installed in your
computer, including but not limited to the following:
•
Diskette Drive
•
Modular bay HDD
•
Internal HDD
•
CD/DVD/CD-RW drive
During the boot routine, the computer starts at the top of the list and scans each enabled device for the
operating system start-up files. When the computer finds the files, it stops searching and starts the
operating system.
To control the boot devices, select (highlight) a device by pressing the down-arrow or up-arrow key, and
then enable or disable the device or change its order in the list.
•
To enable or disable a device, highlight the item and press the space bar. Enabled items appear as white

Drivers
What Is a Driver?
A driver is a program that controls a device such as a printer, mouse, or keyboard. All devices require a
driver program.
A driver acts like a translator between the device and any other programs that use the device. Each device
has its own set of specialized commands that only its driver recognizes.
Dell ships your computer to you with required drivers already installed—no further installation or
configuration is needed.
NOTICE: The optional Drivers and Utilities CD may contain drivers for operating systems that are not on your
computer. Ensure that you are installing software appropriate for your operating system.
Many drivers, such as the keyboard driver, come with your Microsoft® Windows® operating system. You
may need to install drivers if you:
•
Upgrade your operating system.
•
Reinstall your operating system.
•
Connect or install a new device.
Identifying Drivers
If you experience a problem with any device, identify whether the driver is the source of your problem
and, if necessary, update the driver.
1 Click Start→ Control Panel→ System.
2 Click Hardware→ Device Manager.
3 Scroll down the list to see if any device has an exclamation point (a yellow circle with a [!]) on the
device icon.
If an exclamation point is next to the device name, you may need to reinstall the driver or install a new
driver (see "Reinstalling Drivers and Utilities" on page 91).
Reinstalling Drivers and Utilities
NOTICE: The Dell Support website at support.dell.com and your Drivers and Utilities CD provide approved drivers
for Dell™ computers. If you install drivers obtained from other sources, your computer might not work correctly.
Using Windows XP Device Driver Rollback
If a problem occurs on your computer after you install or update a driver, use Windows XP Device Driver
Rollback to replace the driver with the previously installed version.

Problems With Your Order
If you have a problem with your order, such as missing parts, wrong parts, or incorrect billing, contact
Dell for customer assistance. Have your invoice or packing slip handy when you call. For the telephone
number to call, see the contact numbers for your region.
Product Information
If you need information about additional products available from Dell, or if you would like to place an
order, visit the Dell website at www.dell.com. For the telephone number to call to speak to a sales
specialist, see the contact numbers for your region.
Returning Items for Warranty Repair or Credit
Prepare all items being returned, whether for repair or credit, as follows:
1 Call Dell to obtain a Return Material Authorization Number, and write it clearly and prominently on
the outside of the box.
For the telephone number to call, see the contact numbers for your region.
2 Include a copy of the invoice and a letter describing the reason for the return.
3 Include a copy of the Diagnostics Checklist indicating the tests you have run and any error messages
reported by the Dell Diagnostics.
4 Include any accessories that belong with the item(s) being returned (power cables, software floppy
disks, guides, and so on) if the return is for credit.
5 Pack the equipment to be returned in the original (or equivalent) packing materials.
You are responsible for paying shipping expenses. You are also responsible for insuring any product
returned, and you assume the risk of loss during shipment to Dell. Collect On Delivery (C.O.D.)
packages are not accepted.
Returns that are missing any of the preceding requirements will be refused at Dell’s receiving dock and
returned to you.
Before You Call
NOTE: Have your Express Service Code ready when you call. The code helps Dell’s automated-support telephone system
direct your call more efficiently.
Remember to fill out the Diagnostics Checklist. If possible, turn on your computer before you call Dell
for assistance and call from a telephone at or near the computer. You may be asked to type some
commands at the keyboard, relay detailed information during operations, or try other troubleshooting
steps possible only at the computer itself. Ensure that the computer documentation is available.
CAUTION: Before working inside your computer, follow the safety instructions in your Product Information
Guide.

Cleaning Your Computer
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product
Information Guide.
Computer, Keyboard, and Display
CAUTION: Before you clean your computer, disconnect the computer from the electrical outlet and remove any
installed batteries. Clean your computer with a soft cloth dampened with water. Do not use liquid or aerosol
cleaners, which may contain flammable substances.
•
Use a can of compressed air to remove dust from between the keys on the keyboard.
NOTICE: To avoid damaging the computer or display, do not spray cleaning solution directly onto the display. Only
use products specifically designed for cleaning displays, and follow the instructions that are included with the
product.
•
Moisten a soft, lint-free cloth with either water or a display cleaner, and wipe the display until it is
clean.
•
Moisten a soft, lint-free cloth with water and wipe the computer and keyboard. Do not allow water
from the cloth to seep between the touch pad and the surrounding palm rest.
Touch Pad
1 Shut down your computer.
2 Disconnect any attached devices from the computer and from their electrical outlets.
3 Remove any installed batteries. See "Replacing the Battery" on page 31.
4 Moisten a soft, lint-free cloth with water, and wipe it gently across the surface of the touch pad. Do not
allow water from the cloth to seep between the touch pad and the surrounding palm rest.
Floppy Drive
NOTICE: Do not attempt to clean drive heads with a swab. You might accidentally misalign the heads which
prevents the drive from operating.
Clean your floppy drive using a commercially available cleaning kit. These kits contain pretreated
floppies to remove contaminants that accumulate during normal operation.
CDs and DVDs
NOTICE: Always use compressed air to clean the lens in the CD/DVD drive, and follow the instructions that come
with the compressed-air product. Never touch the lens in the drive.
If you notice problems, such as skipping, with the playback quality of your CDs or DVDs, try cleaning
the discs.

1 Hold the disc by its outer edge. You can also touch the inside edge of the center hole.
NOTICE: To avoid damaging the surface, do not wipe in a circular motion around the disc.
2 With a soft, lint-free cloth, gently wipe the bottom of the disc (the unlabeled side) in a straight line
from the center to the outer edge of the disc.
For stubborn dirt, try using water or a diluted solution of water and mild soap. You can also purchase
commercial products that clean discs and provide some protection from dust, fingerprints, and
scratches. Cleaning products for CDs are also safe to use on DVDs.

text editor. Text editors do not usually provide word wrap
or formatting functionality (the option to underline,
change fonts, and so on).
travel module — A plastic device designed to fit inside
the module bay of a portable computer to reduce the
weight of the computer.
UMA — unified memory allocation — System memory
USB — universal serial bus — A hardware interface for a
low-speed device such as a USB-compatible keyboard,
mouse, joystick, scanner, set of speakers, printer,
broadband devices (DSL and cable modems), imaging
devices, or storage devices. Devices are plugged directly in
to a 4-pin socket on your computer or in to a multi-port
hub that plugs in to your computer. USB devices can be
connected and disconnected while the computer is turned
on, and they can also be daisy-chained together.
UTP — unshielded twisted pair — Describes a type of
cable used in most telephone networks and some
computer networks. Pairs of unshielded wires are twisted
to protect against electromagnetic interference, rather
than relying on a metal sheath around each pair of wires to
protect against interference.
UXGA — ultra extended graphics array — A video
standard for video cards and controllers that supports
resolutions up to 1600 x 1200.
video controller — The circuitry on a video card or on the
system board (in computers with an integrated video
controller) that provides the video capabilities—in
combination with the monitor—for your computer.
video memory — Memory that consists of memory chips
dedicated to video functions. Video memory is usually
faster than system memory. The amount of video memory
installed primarily influences the number of colors that a
program can display.
video mode — A mode that describes how text and
graphics are displayed on a monitor. Graphics-based
software, such as Windows operating systems, displays in
video modes that can be defined as x horizontal pixels by y

being changed or destroyed. To write-protect a 3.5-inch
floppy disk, slide its write-protect tab to the open
position.
video resolution — See resolution.
WWAN — wireless wide area network. See Mobile
Broadband network.
virus — A program that is designed to inconvenience you
or to destroy data stored on your computer. A virus
program moves from one computer to another through an
infected disk, software downloaded from the Internet, or
e-mail attachments. When an infected program starts, its
embedded virus also starts.
A common type of virus is a boot virus, which is stored in
the boot sectors of a floppy disk. If the floppy disk is left in
the drive when the computer is shut down and then
turned on, the computer is infected when it reads the
boot sectors of the floppy disk expecting to find the
operating system. If the computer is infected, the boot
virus may replicate itself onto all the floppy disks that are
read or written in that computer until the virus is
eradicated.
V — volt — The measurement of electric potential or
electromotive force. One V appears across a resistance of 1
ohm when a current of 1 ampere flows through that
resistance.
W — watt — The measurement of electrical power. One
W is 1 ampere of current flowing at 1 volt.
WHr — watt-hour — A unit of measure commonly used
to indicate the approximate capacity of a battery. For
example, a 66-WHr battery can supply 66 W of power for
1 hour or 33 W for 2 hours.
WXGA — wide-aspect extended graphics array — A video
standard for video cards and controllers that supports
resolutions up to 1280 x 800."
XGA — extended graphics array — A video standard for
video cards and controllers that supports resolutions up to
1024 x 768.
ZIF — zero insertion force — A type of socket or
connector that allows a computer chip to be installed or
removed with no stress applied to either the chip or its
socket.
Zip — A popular data compression format. Files that have
been compressed with the Zip format are called Zip files
and usually have a filename extension of .zip. A special
kind of zipped file is a self-extracting file, which has a
filename extension of .exe. You can unzip a self-extracting
file by double-clicking it.
Zip drive — A high-capacity floppy drive developed by
Iomega Corporation that uses 3.5-inch removable disks
called Zip disks. Zip disks are slightly larger than regular
floppy disks, about twice as thick, and hold up to 100 MB
of data.
wallpaper — The background pattern or picture on the
Windows desktop. Change your wallpaper through the
Windows Control Panel. You can also scan in your favorite
picture and make it wallpaper.
WLAN — wireless local area network. A series of
interconnected computers that communicate with each
other over the air waves using access points or wireless
routers to provide Internet access.
write-protected — Files or media that cannot be changed.
Use write-protection when you want to protect data from
