Lenovo 3658 - Manual (Page 45)

Make sure that any security cables you installed do not interfere with other
computer cables.
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 a security slot at the rear of your computer and is operated
with a key. See Figure 33. 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 a security cable directly from Lenovo by searching on
Kensington at:
