Security Features

This chapter describes how to protect your computer against unauthorized use, computer viruses and theft.

Passwords

Setting a password will help protect against unauthorized access to your computer. When a password is set and the computer is turned on or resumes from the suspend-to-disk mode, the system will require a password.

If you lose your password, you will be unable to access the computer or change the configuration. Make sure you select a password you will never forget, and write it down and save it in a secure place. Otherwise, you will have to contact your dealer for assistance.

If you enter a wrong password three times, the message System Disabled appears. Slide the power switch to turn off the computer, turn it on again, and enter the correct password.

Supervisor Password and User Password

Two types of passwords limit the access at different levels. To set the user password, you always have to set the supervisor password. When you set the two passwords, a person who knows only the user password has the limitations below:
