An integrated cable lock, sometimes referred to as the Kensington lock, can be used to secure your
computer to a desk, a table, or other non-permanent fixture. The integrated cable lock attaches to the
integrated cable lock slot in the rear of your computer and is operated with a key. See “Rear view” on page 9
for the location of the integrated cable lock slot. This is the same type of lock used with many notebook
computers. You can order an integrated cable lock from Lenovo by searching for Kensington at:
