• Attach a commercially available antitheft device to the security lock 
slot (see “Docking Control Base Controls and Indicators”) on the 
docking device.
Antitheft devices usually include a segment of metal-stranded cable 
with an attached locking device and associated key. Dell recommends 
that you use a Kensington lock. For instructions on installing this kind 
of antitheft device, see the documentation that accompanied the 
device.
Dell Diagnostics
The Dell Diagnostics that came with your Dell Latitude computer includes 
tests that help you troubleshoot the controllers in your docking device.
The subtests in the Network Interface test group of the Dell Diagnostics 
verify the basic operation of the network controller in the docking device. 
They test the controller's internal functions, including read and write access 
to its registers and internal transmit and receive (loopback) capability.
The subtests in the Serial/Infrared Ports test group check the docking 
device's interface with external devices (such as a serial mouse or a printer). 
The subtests in this test group are not intended as a diagnostic test for the 
external device itself.
The subtests in the USB test group check the docking device's interface 
with external devices (such as a mouse). The subtests in this test group are 
not intended as a diagnostic test for the external device itself.
For complete instructions on using the Dell Diagnostics, see your 
computer's User's Guide.
