** When using an external monitor and simultaneously displaying an
image on the internal display, the image on the external monitor may
not fill the screen.
*** This problem indicates that the backlight or its power circuitry has
failed. Since you cannot observe the POST results on the display
panel when the backlight is not functioning, connect the unit to an
external monitor before powering the unit up. If an external monitor
is not available, verify that POST completes by opening and closing
the display, listening for the single or double beep, and watching
for the LEDs to turn on at the front of the computer.
**** The spare display panel, inverter board, display cable, and display
enclosure for the 9.5 color TFT models come preinstalled in a
display assembly. To replace these parts on the 9.5-inch color TFT
models, replace the entire display assembly.
***** The brightness adjustment function on TFT panels must be tested with
the display bezel on, since these panels contain a light feedback
circuit. Outside light affects the operation of the circuit and
does not allow the brightness to adjust.
****** Blocks usually appear in an even fraction of the display (1/2, 1/4,

NOTE: To perform a self-test on an external VGA color or monochrome
monitor, complete the following steps:
1. Turn off the monitor.
2. Turn off the computer.
3. Disconnect the monitor signal cable from the computer.
4. Turn on the monitor and allow it to warm up for one minute.
The screen should be white. A narrow black border may also appear on the
left and right sides of the display. Either of these displays indicates
that the monitor is working properly.

Solving Network Problems
This section contains guidelines for troubleshooting common Ethernet
network problems. These guidelines are intended for use when you have
determined that the computer in the Compaq SmartStation is not
communicating with the network. These guidelines do not discuss the process
of troubleshooting the network cable.
The following are common problems to check first: 
						

							o Ensure that the network cable is securely attached to the expansion base.
A loose cable is the most common cause of network problems. If the cable
is loose, secure it and see if the computer communicates with the
network.
o Ensure that the I/O address and interrupt level do not conflict with
another option.
o Determine whether another computer other than the computer currently in
use has communicated with the network from the expansion base. If so,
determine whether anything was added or changed that could have stopped
the network interface from working.
o Run Computer Checkup (TEST) to test the network interface and determine
if a problem is being caused by a controller or by a cable. Computer
Checkup can be run before installing the network drivers to verify that
the network interface is working correctly.
IMPORTANT: For the Compaq LTE Lite Family of Personal Computers, use the
diagnostics diskette included with the SmartStation Adapter
to run Computer Checkup.
Network Adapter Patch
A file from the Network Install diskette must be installed when using the
Compaq LTE Elite with certain network adapters while in certain operating
environments. The Network Install diskette is included with the Compaq
SmartStation and the Compaq LTE Lite Desktop Expansion Base Upgrade Kit.
The README.DOC file on the diskette details how to use each file and
specifies the network interface cards and network operating systems that
require it.
NOTE: Files on the diskette are not needed to use the Compaq LTE Lite with
a network adapter or the Compaq LTE Elite with the built-in Ethernet
controller in the Compaq SmartStation.
Refer to the correct version of Service Advisory 737 for a comprehensive
list of network adapters that require a patch, which include the following:
o Eagle Etherxpert EP2000 Plus
o Madge AT Ringnode
o Madge ISA Ringnode
o Madge Smart AT Ringnode
o Madge Smart 16/4 AT Ringnode
o Novell NE-2000
o Standard Microsystems Corp. Arcnet PC 130
o Standard Microsystems Corp. Arcnet PC 130E
o Tiara Lancard/A
o Silicom Modular Pocket Ethernet Adapter
o Xircom Pocket Arcnet Adapter
NOTE: Contact Xircom to request a software driver for the Xircom Pocket
Ethernet Adapter III.
