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
