Securing the Media Base
NOTE: If the computer is docked to the media base and an antitheft device is attached to the security cable slot on
the media base, you cannot undock the computer without first removing the antitheft device.
1 Attach a commercially available antitheft device to the security cable slot on the media base.
Antitheft devices usually include a segment of metal-stranded cable with an attached locking device and
associated key. For instructions on installing this kind of antitheft device, see the documentation that
accompanied the device.
