Chapter 4. Security

This chapter provides information about how to protect your computer from theft and unauthorized use.

Attaching a Kensington-style cable lock

You can use a Kensington-style cable lock to secure your computer to a desk, table, or other non-permanent
fixture. The cable lock connects to the security-lock slot at the rear of your computer. Depending on the type
selected, the cable lock can be operated with a key or combination. 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 such a cable lock directly from Lenovo by searching for

Kensington
