Securing 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.
Security features include hardware and software locks — a security notch and
passwords.
Using a computer security lock
A security keylock notch, located on the chassis of the computer, lets you
connect a Kensington-compatible computer security lock.
Wrap a computer security lock cable around an immovable object such as a
table or the handle of a locked drawer. Insert the lock into the notch and turn
the key to secure the lock. Some keyless models are also available.
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 "BIOS utility" on page 49.
• User Password secures your computer against unauthorized use. Combine
the use of this password with password checkpoints on boot-up and
resume from Hibernation 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 for maximum security.
Important! Do not forget your Supervisor Password! If you forget
your password, please get in touch with your dealer or an
authorized service center.
