Make sure that any security cables you install do not interfere with other computer cables.

Integrated cable lock

With an integrated cable lock (sometimes referred to as a 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. The cable lock also locks the buttons used to open the cover. This is the same type of lock used with many laptop computers. You can order a cable lock directly from Lenovo. Go to http://www.lenovo.com/support and search on Kensington.

Password protection
