Chapter 4. Security

This chapter provides information about how to protect your computer from theft and unauthorized use.

Security features

The following security features are available on your computer:

Computrace Agent software embedded in firmware

The Computrace Agent software is an IT asset management and computer theft recovery solution. The software detects if changes have been made on the computer, such as hardware, software, or the computer call-in location.

Note: You might have to purchase a subscription to activate the Computrace Agent software.

Ability to enable and disable devices and USB connectors

For more information, see “Enabling or disabling a device” on page 45.

Integrated fingerprint reader (available on some models)

Depending on the models of your computer, the keyboard may have an integrated fingerprint reader. By enrolling your fingerprint and associating it with a Power-on Password, a Hard Disk Password, or both passwords beforehand, you can start the computer, log on to the system, and enter the Setup Utility program by swiping your finger over the reader, without typing a password. Thus fingerprint authentication can replace passwords and enable simple and secure user access.

Startup sequence control

For more information, see “Selecting or changing the startup device sequence” on page 45.

Startup without keyboard or mouse

Your computer is able to log in to the operating system without keyboard or mouse connected.
