							10 Security
Protecting the computer
NOTE:Security solutions are designed to act as deterrents. These deterrents may not prevent a
product from being mishandled or stolen.
NOTE:In some countries or regions, the computer supports CompuTrace, which is an online security-
based tracking and recovery service. If the computer is stolen, CompuTrace can track the computer if
the unauthorized user accesses the Internet. You must purchase the software and subscribe to the
service in order to use CompuTrace. For information about ordering the CompuTrace software, go to
the HP Web site at 
http://www.hpshopping.com.
Security features provided with your computer can protect the computer, personal information, and data
from a variety of risks. The way you use your computer will determine which security features you need
to use.
The Windows® operating system offers certain security features. Additional security features are listed
in the following table. Most of these additional security features can be configured in the Computer Setup
utility (referred to hereafter as Computer Setup).

*Computer Setup is a preinstalled, ROM-based utility that can be used even when the operating system is not working or will
not load. You can use either a pointing device (TouchPad, pointing stick, or USB mouse) or the keyboard to navigate and make
selections in Computer Setup.

							Using passwords
Most security features use passwords. Whenever you set a password, write down the password and
store it in a secure location away from the computer. Note the following password considerations:
●Setup and DriveLock password are set in Computer Setup and are managed by the system BIOS.
●The embedded security password, which is an HP ProtectTools Security Manager password, can
be enabled in Computer Setup to provide BIOS password protection in addition to their normal HP
ProtectTools functions. The embedded security password is used with the optional embedded
security chip.
●Windows passwords are set only in the Windows operating system.
●If you forget the BIOS administrator password set in Computer Setup, you can use HP SpareKey
to access the utility.
●If you forget both the DriveLock user password and the DriveLock master password set in Computer
Setup, the hard drive that is protected by the passwords is permanently locked and can no longer
be used.
You can use the same password for a Computer Setup feature and for a Windows security feature. You
can also use the same password for more than one Computer Setup feature.
Use the following tips for creating and saving passwords:
●When creating passwords, follow requirements set by the program.
●Write down your passwords and store them in a secure place away from the computer.
●Do not store passwords in a file on the computer.
The following tables list commonly used Windows and BIOS administrator passwords and describe their
functions.

							BIOS administrator passwordsFunction
DriveLock user passwordProtects access to the internal hard drive that is protected by
DriveLock, and is set under DriveLock Password during the
enable process.
TPM embedded security password When enabled as a BIOS administrator password, protects
access to the computer contents when the computer turns on,
restarts, or exits Hibernation.
This password requires the optional embedded security chip
to support this security feature.
BIOS administrator password
The Computer Setup BIOS administrator password protects the configuration settings and system
identification information in Computer Setup. After this password is set, it must be entered to access
Computer Setup and to make changes using Computer Setup.
Note the following characteristics of the BIOS administrator password:
●It is not interchangeable with a Windows administrator password, although both passwords can be
identical.
●It is not displayed as it is set, entered, changed, or deleted.
●It must be set and entered with the same keys. For example, a BIOS administrator password set
with keyboard number keys will not be recognized if you enter it thereafter with embedded numeric
keypad number keys.
●It can include any combination of up to 32 letters and numbers and it is not case sensitive unless
mandated by the administrator.

							Entering a BIOS administrator password
At the BIOS administrator password prompt, type your password (using the same kind of keys you
used to set the password), and then press enter. After 3 unsuccessful attempts to enter the BIOS
administrator password, you must restart the computer and try again.
Using Computer Setup DriveLock
CAUTION:To prevent the DriveLock-protected hard drive from becoming permanently unusable,
record the DriveLock user password and the DriveLock master password in a safe place away from your
computer. If you forget both DriveLock password, the hard drive will be permanently locked and can no
longer be used.
DriveLock protection prevents unauthorized access to the contents of a hard drive. DriveLock can be
applied only to the internal hard drive(s) of the computer. After DriveLock protection is applied to a drive,
a password must be entered to access the drive. The drive must be inserted into the computer or an
advanced port replicator in order for it to be accessed by the DriveLock password.
To apply DriveLock protection to an internal hard drive, a user password and a master password must
be set in Computer Setup. Note the following considerations about using DriveLock protection:
●After DriveLock protection is applied to a hard drive, the hard drive can be accessed only by entering
either the user password or the master password.
●The owner of the user password should be the day-to-day user of the protected hard drive. The
owner of the master password may be either a system administrator or the day-to-day user.
●The user password and the master password can be identical.
●You can delete a user password or master password only by removing DriveLock protection from
the drive. DriveLock protection can be removed from the drive only with the master password.
