YOUR

 

COMPUTER

Your computer is a valuable investment that you need to take care of. 
Learn how to protect and take care of your computer.

Using passwords

Passwords protect your computer from unauthorized access. Setting 
these passwords creates several different levels of protection for your 
computer and data:
• Supervisor Password prevents unauthorized entry into the BIOS 

utility. Once set, you must enter this password to gain access to the 
BIOS utility. 

See Setting passwords on page 25

.

• User Password secures your computer against unauthorized use. 

Combine the use of this password with password checkpoints on 
boot-up and resume from Hibernation (if available) for maximum 
security.

• Password on Boot secures your computer against unauthorized 

use. Combine the use of this password with password checkpoints 
on boot-up and resume from Hibernation (if available) for maximum 
security.

Entering passwords

When a password is set, a password prompt appears in the center of 
the display screen.
• When the Supervisor Password is set, a prompt appears when you 

enter the BIOS utility.

• Type the Supervisor Password and press <

Enter

> to access the 

BIOS utility. If you enter the password incorrectly, a warning 
message appears. Try again and press <

Enter

>.

• When the User Password is set and the password on boot 

parameter is enabled, a prompt appears at boot-up.

Important

Do not forget your Supervisor Password! If you forget your password, 
please get in touch with your dealer or an authorized service center.
