Integrated security cable

With an integrated cable lock (sometimes referred to as the Kensington lock), you can 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. This is the same type of lock used with many laptop computers. You can order a security cable directly from IBM. Go to http://www.pc.ibm.com/support and search on Kensington.
