Chapter 4. Security
This chapter provides information about protecting your computer from theft and unauthorized use.
Attaching a mechanical lock
You can attach a mechanical lock to your computer to prevent it from being removed without your
permission.
Attach a mechanical lock to the keyhole of the computer; then secure the chain on the lock to a stationary
object. Refer to the instructions shipped with the mechanical lock.
Note: You are responsible for evaluating, selecting, and implementing the locking devices and security
features. Lenovo makes no comments, judgments, or warranties about the function, quality, or performance
of locking devices and security features.
Using passwords
Using passwords helps prevent your computer from being used by others. Once you set a password and
enable it, a prompt appears on the screen each time you power on the computer. Enter your password at the
prompt. The computer cannot be used unless you enter the correct password.
Note: This password can be a combination of one to seven alphanumeric characters.
For more information about how to set the password, refer to the online help information system on the right
screen of the BIOS program.
Note: To enter the BIOS program, press F1 when the Lenovo logo is displayed on the screen while the
computer is starting up.
Using a fingerprint reader
With the fingerprint reader, in addition to registering fingerprint information and using it as a password for
Windows operating system or Web site logon, you also can launch applications quickly and encrypt private
data with your fingerprint to secure your computer. For more information, refer to the online help
information system of the fingerprint software.
Using the Active Protection System program
Some Lenovo models have the Active Protection System program preinstalled.
As a reliable safeguard, the Active Protection System program reduces the possibility of shock damage to the
hard disk drive that may result in data loss. When your computer is subject to shock or excessive vibration,
the shock sensor in the computer detects the condition and stops the hard disk drive until the environment is
stable again.
