To help prevent hardware theft and unauthorized access to your computer, several security lock options are available. The following sections help you identify and install the various types of locks that might be available for your computer. In addition to physical locks, unauthorized use of your computer can be prevented by a software lock that locks the keyboard until a correct password is typed in.
Make sure that any security cables you install do not interfere with other computer cables.
Identifying security locks
The following illustration will help you to identify the various types of security locks that your computer might have.
- Holes for Rope clip (U-bolt)
- Slot for integrated cable lock (Kensington lock)
- Cover lock
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 us. Go to /ContentResources/Migrated Assets/think/support and search on Kensington.
Using a 3/16 inch (5 mm) security rope clip (sometimes referred to as a U-bolt), a steel security cable, and a padlock you can secure your computer to a desk, table, or other non-permanent fixture. For computers designed to accommodate the rope clip, knockouts at the rear of the chassis are provided.
To install a rope clip
- Remove the cover. See "Cover removal".
- Use a tool, such as a screwdriver, to remove the two metal knockouts.
- Insert the rope clip through the rear of the chassis and install the nuts using either an adjustable or an appropriate sized wrench.
- Replace the cover.
- Thread the security cable through the rope clip and around an object that is not part of or permanently attached to the building structure or foundation, and from which it cannot be removed; then fasten the cable together with a lock.

To deter unauthorized use of your computer, you can use the Setup Utility program to set a password. When you turn on your computer you are prompted to type the password to unlock the keyboard for normal use.
