English 54 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 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 60. • 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.
