Integrated cable lock

An integrated cable lock, sometimes referred to as the Kensington lock, can be
used to secure your computer to a desk, table, or other non-permanent fixture. The
cable lock attaches to the integrated cable lock slot at the rear of your computer
and is operated with a key. The cable lock also locks the buttons used to open the
computer cover. This is the same type of lock used with many notebook
computers. You can order an integrated cable lock directly from Lenovo by
searching for Kensington at:

Password protection

To deter unauthorized use of your computer, you can use the Setup Utility
program to set a password. When you turn on your computer, you are prompted
to type the password. The computer cannot be used until a valid password is
typed in. Refer to Chapter 4, "Using the Setup Utility," on page 49 for more
information.
