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 20

.

• 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

.

Important

Do not forget your Supervisor Password! If you forget your

password, please get in touch with your dealer or an authorized

service center.
