new CRUs.
Obtaining device drivers
You can obtain device drivers for operating systems that are not preinstalled at
http://www.lenovo.com/support. Installation instructions are provided in readme files with the device-driver
files.
Basic security features
There are several security options available to help you prevent hardware theft and unauthorized access to
your computer. In addition to physical locks, you can also prevent unauthorized use of your computer by a
software lock that locks the keyboard until a correct password is typed in.
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. The cable lock also locks the computer cover. See Figure
35 "Installing an integrated cable lock" on page 38. 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:
http://www.lenovo.com/support
Note: Make sure that the integrated cable lock you installed does not interfere with other computer cables.
