battery charge is low (see "Configuring Power Management Settings" on page 33).
CAUTION: Using an incompatible battery may increase the ri sk of fire or explosion. Replace the battery
only with a compatible battery purchased from Dell. The lit hium ion battery is design ed to work with your
Dell computer. Do not use a battery from other computers with your computer.

30 Using a Battery CAUTION: Do not dispose of batterie s with household waste. When your ba ttery no longer ho lds a charge, call
your local waste disposal or environm ental 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 battery meter icon
( or ), 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 <Fn><F3> 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, click the QuickSet icon in the Microsoft® Windows® taskbar,
and click Help .
Microsoft® Windows® Power Meter
The Windows Power Meter indicates the remaining battery charge. To check the Power Meter, double-
click the battery meter icon ( or ) on the taskbar.
If the computer is connected to an el ectrical 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 largel y determined by the number of times it is charged. After hundreds of
charge and discharge cycles, batteries lose some charg e capacity—or battery health. That is, a battery can
show a status of "charged" but mainta in 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 approxim ately 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.

Using a Battery 31Check the Battery Health
NOTE: You can check battery health in on e 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-cl ick the QuickSet
icon in the Microsoft® Wi ndows® 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 cond ition, and more than 80
percent of its original charge capacity remains. Eac h light represents incremental degradation. If five
lights appear, less than 60 percent of the charge ca pacity remains, and you should consider replacing the
battery. See "Specifications" on page 131 for more information about the battery operating time.
Low-Battery Warning
NOTICE: To avoid losing or corrupting data, save your wo rk immediately after a low-battery warning. Then
connect the computer to an ele ctrical outlet. If the battery runs compl etely out of power, hibernate mode begins
automatically.
By default, a pop-up window warns you when the batt ery charge is approximately 90 percent depleted.
Y ou can change the settings for the battery alarms in QuickSet or the Power Options Properties window.
See "Configuring Power Management Settings" on pa ge 33 for information ab out accessing QuickSet or
the Power Options Properties window.
Conserving Battery Power
Perform the following action s to conserve battery power:
 Connect the computer to an electr ical 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 31).
 Use the Power Management Wizard to select options to optimize your computer’s power usage. These

Using Cards 59Using Cards
Card Types
See "Specifications" on page 131 for information on supported card types.
NOTE: A PC Card is not a bootable device.
The PC Card slot has one connector that supports a sing le T ype I or T ype II card. The PC Card slot
supports CardBus technology and extended PC Cards. "T ype" of card refers to its thickness, not its
functionality.
The ExpressCard slot has one connector that supports 54-mm cards. The slot also supports adapters
for 34-mm cards.
Card Blanks
Y our computer shipped with a plastic blank installed in the card slots. Blan ks protect unused slots
from dust and other particles. Save the blank for use when no PC Card is installed in the slot; blanks
from other computers may not fit your computer.
To remove the blank, see "Removing a Card or Blank" on page 61.
Extended Cards
An extended card (for example, a wireless netwo rk adapter) is longer than a standard card and
extends outside the computer. Follow these precaut ions when using extended PC or ExpressCards:
 Protect the exposed end of an installed card. St riking the end of the card can damage the system
board.
 Always remove an extended card before you pack the computer in its carrying case.
Installing a PC Card or ExpressCard
Y ou can install a PC Card or ExpressCard in the computer while the computer is running. The
computer automatically detects the card.
Cards are generally marked with a symbol (such as a triangle or an arrow) to indicate which end to
insert into the slot. The cards are keyed to prevent inc orrect insertion. If card orientation is not clear,
see the documentation that came with the card.

Smart Cards
About Smart Cards
Smart cards are portable credit-card shaped device s with internal integrated circuits. The top surface
of the smart card usually contains an embedde d processor under the gold contact pad. The
combination of the small size and integrated circ uits 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.

64 Securing Your ComputerInstalling a Smart Card
Y ou can install a smart card in the computer whil e the computer is running. The computer automatically
detects the card.
To install a smart card:
1Hold the card so that the gold contact pad is facing upward and pointing toward the smart card slot.
2Slide the smart card into the smart card slot until th e card is completely seated in its connector. The
smart card protrudes approximately .5 inch from the slot. The smart card slot is located below the PC
Card slot.
If you encounter too much resistance, do not forc e the card. Check the card orientation and try again.
Passwords
NOTE: Passwords are disabled when you receive your computer.1gold contact pad 2smart card (top)

Securing Your Computer 65A primary (or system) password, an administrator password, and a hard d rive password all prevent
unauthorized access to your comput er in different ways. The following table identifies types and features
of passwords available on your computer.
NOTE: Some hard drives do not su pport hard drive passwords.
NOTICE: Passwords provide a high level of security for data in your computer or hard dr ive. However, they are not
foolproof. If you require more security, obtain and use additional forms of prote ction, such as smart cards, data
encryption programs, or PC Ca rds with encryption features.
If you forget any of your passwor ds, contact your system administrator or contact Dell (see "Contacting
Dell" on page 143). For your protectio n, 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 mu st 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 a ccounts 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 wit hin 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, yo u can use it instead of the primary password. The
computer does not specifically prompt you for the adm inistrator password.
Using an Administrator Password
The administrator password is desig ned to give system administrators or service technicians access to
computers for repair or reconfiguration. The ad ministrators or technicians can assign identical
administrator passwords to groups of computers, allowing you to assign a unique primary password.
To set or change adminis trator passwords, access User Accounts from the Control Panel.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

66 Securing Your ComputerWhen you set an administrator password, the Configure Setup option becomes available in the system
setup program. The Configure Setup option allows you to restrict acce ss to system setup in the same way
that a primary password rest ricts access to the computer.
The administrator password can be used instead of the primary pa ssword. 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 pro vide access to the hard
drive when a hard drive password is assigned.
If you forget the primary password an d do not have an administrator pa ssword assigned, or if you have
both a primary and an administra tor password assigned but forget them both, contact your system
administrator or contact Dell (s ee "Contacting Dell" on page 143).
Using a Hard Drive Password
The hard drive password helps protect the data on your hard drive from unauthorized access. Y ou can
also assign a password for an external hard drive (if o ne 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 yo u turn on the computer and each
time you restore the computer to normal operation from standby mode.
If the hard drive password is enab led, 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 <Enter>.
If you do not enter a password wit hin 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 <Enter> 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 progra m 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 wa s 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 . T wo different passwords provide greater security.
NOTE: The administrator password provides access to the computer, but it does not pro vide access to the hard
drive when a hard drive password is assigned.
If the administrative password is installed when the user creates the primary hard disk password, then the
administrative password can be used in place of the primary hard disk password. This feature allows an
administrator to unlock password-prote cted hard disks as long as an administrative password is installed
before deploying the computers.

Securing Your Computer 67There are two behaviors associated with this feature th at help to preserve the integrity of the hard disk’s
password:
 The administrative password will only work to unlo ck a hard disk on the computer on which the hard
disk password was created. This means a password-p rotected hard disk can not be removed from one
computer, placed in a second computer and be unlo cked using the administrative password on the
second computer.
 Installing an administrative password on a computer after the hard disk password has been created will
not enable unlocking of the hard dis k using the administrative password.
Trusted Platform Module (TPM)
NOTE: Computers shipping into China are not equipped with the TPM feature.
NOTE: The TPM feature supports encryption on ly if the operating system supports TPM. For more information, see
the TPM software documentati on and the help files tha t came with the software.
TPM is a hardware-based security feature that can be used to create and manage computer-generated
encryption keys. When combined wi th security software, the TP M enhances existing network and
computer security by enabling features such as file protection capabilities and protected e-mail. The
TPM feature is enabled through a system setup option.
NOTICE: To secure your TPM data and enc ryption keys, follow the backup procedures documented in the Archive
and Restore section of the EMBASSY Security Center help file. In the event of these backups being incomplete,
lost, or damaged, Dell will be unable to assist in the recovery of encrypted data.

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 electrom agnetic interference, rather
than relying on a metal sheath ar ound 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.
V
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
vertical pixels by z colors. Character-based software, such
as text editors, displays in video modes that can be defined as x columns by y rows of characters.

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 down loaded 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 in fected when it reads the
boot sectors of the floppy disk expecting to find the operating system. If the co mputer is infected, the boot
virus may replicate itself onto all the floppy disks that are
read or written in that co mputer 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
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 ca n supply 66 W of power for
1 hour or 33 W for 2 hours.
wallpaper — The background pattern or picture on the
Windows desktop. Change your wallpaper through the
Windows Control Panel. Y ou 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 usi ng 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 being changed or destroyed. To write-protect a 3.5-inch floppy disk, slide its writ e-protect tab to the open
position.WWAN — wireless wide area network. A wireless high-
speed data network using cellu lar technology and covering
a much larger geographic area than WLAN.
WXGA — wide-aspect extended graphics array — A video
standard for video cards and controllers that supports
resolutions up to 1280 x 800."
X
XGA — extended graphics array — A video standard for
video cards and controllers that supports resolutions up to 1024 x 768.
Z
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. Y ou can unzip a self-extracting
file by double-clicking it.
Zip drive — A high-capacity flop py 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.
