About Passwords
A primary 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.
If you forget any of your passwords, contact your system administrator or contact Dell. 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 Password
The primary password allows you to protect the computer from unauthorized access.
After assigning a primary password, you must enter it each time you turn on your computer. The following message appears each time you turn on the
computer:
Please type in the primary or administrator password and press <Enter>.
To continue, enter your password (with no more than eight characters).
If you do not enter a password within 2 minutes, the computer returns to its previous operating state.
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 the primary password.
When you set an administrator password, the Configure Setup option becomes available in system setup. The Configure Setup option allows you to restrict
NOTE: Passwords are disabled when you receive your computer.
Type of Password
Features
Primary
l Protects the computer from unauthorized
access
Administrator
l Gives system administrators or service
technicians access to computers for repair or
reconfiguration
l Allows you to restrict access to system setup
in the same way a primary password restricts
access to the computer
l Can be used instead of the primary password
Hard drive
l Helps protect the data on your hard drive or
external hard drive (if one is being used) from
unauthorized access
NOTE: OnlyharddrivespurchasedfromDellforusewiththeDellPrecision™D-Family computers 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.
NOTICE: If you disable the administrator password, the primary password is also disabled.
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.
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.
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, the following message appears each time you turn on the computer:
Please type in the hard-disk drive password and press <Enter>.
To continue, enter your password (with no more than eight characters). Press <Esc> to return the computer to its previous operating state.
If you do not enter a password within 2 minutes, the computer returns to its previous operating state.
If you enter the wrong password, the following message appears:
Invalid password
[Press Enter to retry]
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.
Assigning an Asset Tag
The Asset Tag utility allows you to enter an asset tag that you or your company assigns to the computer. After you enter an asset tag, the tag appears in the
system setup screens.
You can also use the Asset Tag utility to enter an owner tag that appears in the system log-on screen and with the primary password prompt.
Download the Dell Portables Asset Tag utility from the support.dell.com website to create bootable media (such as a bootable CD or floppy disk), and then
use the bootable media to assign an asset tag.
