Passwords
DellPrecision™MobileWorkstationM70User'sGuide
About Passwords
Using a Primary/System Password
Using an Administrator Password
Using a Hard Drive Password
Assigning an Asset Tag
Enabling Trusted Platform Module (TPM)
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/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/system password, you must
enter it each time you turn on your computer.
If you have assigned an administrator password, you can use it instead of the primary/system 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/system password.
To set or change administrator passwords, access User Accounts, which is located in the Control Panel.
1. To open User Accounts, click the Start button and point to Settings.
2. Click Control Panel.
3. Double-click User Accounts.
NOTE: Passwords are disabled when you receive your computer.
Type of Password
Features
Primary/System
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.

4. In the User Accounts window, click the administrator user and click the Reset Password button.
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 or system password restricts access to the computer.
You can now use the administrator password instead of the system password. Whenever you are prompted to enter the primary/system password, you can
enter the administrator password.
If you forget the primary/system 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 system asks you to type in the hard-disk drive password each time you turn on the computer.
If you enter the wrong password, a message similar to the following example 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/system password are the same, the computer prompts you only for the
primary/system password. If the hard drive password is different from the primary/system 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.
1. Save and close any open files and exit any open programs.
2. Ensure that you have a drive for the bootable media (such as a floppy drive or a CD drive).
3. Access the support.dell.com website. Download the Dell Portables Asset Tag utility for your system. Unzip the files and run the Asset Tag utility to
create the bootable media.
4. Boot the computer, using the bootable media:

NOTICE: If you disable the administrator password, the primary/system password is also disabled.
NOTE: The administrator password provides access to the computer, but it does not provide access to the hard drive if a hard drive password is
assigned.
NOTE: The administrator password provides access to the computer, but it does not provide access to a hard drive that is protected by a hard drive
password.
NOTE: The Dell Portables Asset Tag utility may not be available as a download in certain countries.

Removing a PC Card or Blank
Installing a PC Card
PC Card Types
See "Specifications" for information on supported PC Cards.
The PC Card slot has one connector that supports a single Type I or Type II card. The PC Card slot supports CardBus technology and extended PC Cards.
"Type" of card refers to its thickness, not its functionality.
PC Card Blanks
Your computer shipped with a plastic blank installed in the PC Card slot. Blanks 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 PC Card or Blank."
Extended PC Cards
An extended PC Card (for example, a wireless network adapter) is longer than a standard PC Card and extends outside the computer. Follow these
precautions when using extended PC Cards:
l Protect the exposed end of an installed card. Striking the end of the card can damage the system board.
l Always remove an extended PC Card before you pack the computer in its carrying case.
Removing a PC Card or Blank
Press the latch and remove the card or blank. For some latches, you must press the latch twice: once to pop the latch out, and then a second time to pop the
card out.
Save a blank to use when no PC Card is installed in a slot. Blanks protect unused slots from dust and other particles.
NOTE: A PC Card is not a bootable device.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.
NOTICE: Use the PC Card configuration utility (click the icon in the taskbar) to select a card and stop it from functioning before you remove it from

eject button

Installing a PC Card
You can install a PC Card in the computer while the computer is running. The computer automatically detects the card.
PC 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
incorrect insertion. If card orientation is not clear, see the documentation that came with the card.
To install a PC Card:
1. Hold the card with its orientation symbol pointing into the slot and the top side of the card facing up. The latch may need to be in the "in" position
before you insert the card.
2. Slide the card into the slot until the card is completely seated in its connector.
If you encounter too much resistance, do not force the card. Check the card orientation and try again.
The computer recognizes most PC Cards and automatically loads the appropriate device driver. If the configuration program tells you to load the
manufacturer's drivers, use the floppy disk or CD that came with the PC Card.
