NOTE: Some of the features described in this chapter may not be supported by your computer or your
operating system.
Protecting the computer
NOTE: Security solutions are designed to act as deterrents. These deterrents may not prevent a
product from being mishandled or stolen.
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 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).

store it in a secure location away from the computer. Note the following password considerations:
● Setup, power-on, and DriveLock passwords are set in Computer Setup and are managed by the
system BIOS.
● The embedded security password can be enabled in Computer Setup to provide BIOS password
protection. The embedded security password is used with the optional embedded security chip.
● Operating system passwords are set only in the operating system.
