Securing Your Computer
Security Cable Lock
NOTE: Your computer does not ship with a security cable lock.
A security cable lock is a commercially available antitheft device. To use the
lock, attach it to the security cable slot on your Dell™ computer. For more
information, see the instructions included with the device.
NOTICE: Before you buy an antitheft device, ensure that it will work with the
security cable slot on your computer.
Passwords
About 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.
Securing Your Computer 93
Type of Password Features
Primary (or 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
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.
NOTE: Some hard drives do not support hard drive passwords.
When using passwords, observe the following guidelines:
• Choose passwords that you can remember, but not ones that are easy to
guess. For example, do not use the names of family members or pets for
passwords.
• It is recommended that you do not write down passwords. If you do write it
down, however, ensure that the password is stored in a secure place.
• Do not share passwords with other people.
• Ensure that people are not watching you when you type your password(s).
If you forget any of your passwords, contact Dell (see "Contacting Dell" on
page 149). For your protection, Dell technical support staff will ask you for
proof of your identity to ensure that only an authorized person can use the
computer.
Using a Primary (or System) Password
The primary password allows you to protect the computer from unauthorized
access.
When you first start your computer, you must assign a primary password at
the prompt.
94 Securing 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.
To add or change passwords, access User Accounts from the Control Panel.
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 system setup. 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 149).
Securing Your Computer 95
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.
To assign or change a hard drive password, enter system setup (see "System
Setup Program" on page 123).
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 <Enter>.
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 <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
system setup 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.
Trusted Platform Module (TPM)
NOTE: Computers shipping into China and Russia are not equipped with the TPM
feature.
96 Securing Your Computer
NOTE: The TPM feature supports encryption only if the operating system supports
TPM. For more information, see the TPM software documentation and the help files
that 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 with security
software, the TPM 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 encryption keys, follow the backup
procedures documented in the Broadcom Secure Foundation Getting Started
Guide. In the event of these backups being incomplete, lost, or damaged, Dell will
be unable to assist in the recovery of encrypted data.

Computer Tracking Software
Computer tracking software may enable you to locate your computer if it is
lost or stolen. The software is optional and may be purchased when you order
your Dell™ computer, or you can contact your Dell sales representative for
information about this security feature.
NOTE: Computer tracking software may not be available in certain countries.
98 Securing Your Computer
NOTE: If you have computer tracking software and your computer is lost or stolen,
you must contact the company that provides the tracking service to report the
missing computer.
If Your Computer Is Lost or Stolen
• Call a law enforcement agency to report the lost or stolen computer.
Include the Service Tag in your description of the computer. Ask that a
case number be assigned and write down the number, along with the
name, address, and phone number of the law enforcement agency. If
possible, obtain the name of the investigating officer.
NOTE: If you know where the computer was lost or stolen, call a law enforcement
agency in that area. If you do not know, call a law enforcement agency where you
live.
• If the computer belongs to a company, notify the security office of the
company.
• Contact Dell customer service to report the missing computer. Provide the
computer Service Tag, the case number, and the name, address, and phone
number of the law enforcement agency to which you reported the missing
computer. If possible, give the name of the investigating officer.
The Dell customer service representative will log your report under the
computer Service Tag and record the computer as missing or stolen. If
someone calls Dell for technical assistance and gives your Service Tag, the
computer is identified automatically as missing or stolen. The representative
will attempt to get the phone number and address of the caller. Dell will then
contact the law enforcement agency to which you reported the missing
computer.
