The internal microphone is supported by the audio subsystem and connects
to the system board. It is an omnidirectional condenser microphone with a
standard sensitivity of 40dB. The microphone is mounted in a rubber boot
to provide acoustic isolation and is mounted at the right side of the
keyboard, under the CPU cover.
Status Panel
The status panel is located immediately below the LCD panel on the system
unit. The panel displays a series of icons to indicate system status as
described in Table 1-3.
The status panel also contains two status indicator lights. The right
indicator light provides battery status; the left indicator light provides
power-on and Standby (Suspend) status. Access to the display panel for
service requires removal of the CPU cover. The status display is secured
with two screws. The status panel cable plugs into an 8-pin connector on
the processor board.
Processor Board
The processor board supports the following:
o Processor
o DC-to-DC converter is used only with processors that operate at higher
than 75 MHz.
o L2 cache
o System RAM
o System memory expansion connector
o Power, display, and standby switches
o Infrared serial port (IrDA)
o Display panel configuration jumpers
o Power-on password jumper
The computer supports 75, 90, 100, 120, 133-, and 150-MHz Mobile Pentium
processors. The processor is soldered to the processor board, so
replacement is accomplished by replacing the processor board. A heat sink
on the processor and a cooling fan maintain an operating temperature
within the limits specified by the CPU manufacturer and other components.
All I/O buffers operate at 3.3 volts.The 75-MHz processor core operates at
3.3 volts. The 150-MHz processor core operates at 3.1 volts. The 90-Mhz,
100mhz, 120-MHz, and 133-MHz processor cores operate at 2.9 volts. The 2.9
volts is provided by a DC-to-DC converter mounted on the processor board.
The processors are of a tape carrier package (TCP) design that has a high
pin count, low profile, and reduced footprint. The processor is easily
damaged, so the pins and body of the processor should not be touched.
The L2 cache is implemented as direct-mapped, write-back cache with a size
of 256 KB.
The power switch, display switch, and standby (suspend) button are mounted
on the processor board. They are operated by switch actuators mounted on
the CPU cover.
The power switch turns system power on and off. When the switch is pushed
to turn the power off, the system displays a warning message that all
unsaved data will be lost. The shut down process is then completed by
pressing Enter.
The display switch turns the display off and initiates a beep if the
display is closed with the computer on. When used with the standby switch,
the display switch initiates a system restart.
The standby (suspend) button initiates and exits Standby (suspend). As
described above, the standby button, when used with the display switch,
initiates a system restart. When used with the Fn key, the standby button
initiates Hibernation.
The processor board contains 8 MB or 16 MB of onboard memory and can be
expanded to 72 or 80 MB by adding a 64 MB memory expansion board. The
memory expansion boards are available in 8, 16, 32, and 64 MB DRAM
configurations. Each module is composed of two boards assembled together.
The system ROM is shadowed in system memory.
The infrared subsystem (IrDA) provides two-way wireless communication
using infrared as a transmission medium. Proper operation requires the
communicating infrared ports to be within a 30-degree path and no more
than three feet (1 meter) apart.
The processor board must be configured according to the display type. This
is done by setting Jumpers JP2, JP3, and JP4 on the processor board. Use
Table 1-5 to determine proper jumper settings for the display.

The power-on password jumper is also located on the processor board. To
erase the power-on password, set jumper JP1 to pins 1 and 2; set JP1 to
pins 2 and 3 for normal operation. See Chapter 2 for more details.
To remove and replace the processor board, you must first remove the CPU
cover, EMI shield, keyboard, and display unit. The processor board is
secured in place with two screws and is connected to the system board with
two connectors.
System Board
There are three system boards for the computer: one to support the 75 MHz,
90 MHz and 120 MHz processors (LTE 5000, LTE 5100, and LTE 5200); one to

The graphics controller also supports display of real-time video from the
MPEG and TV Video Adapter at a rate of 30 frames per second (fps). It
provides the capability to overlay the video in a Windows screen.
The computer has 1 MB of video DRAM soldered to the system board. There
is no provision for adding additional video memory.
The graphics subsystem is designed to minimize the use of power at all
times. When the system is idle for a set period of time, the controller is
placed in the lowest power state. The LCD panel backlight and panel power
are turned off during periods of inactivity after a timeout as determined
by the user in Computer Setup. The system supports Energy Star monitors
and allows the feature to be turned on/off from Computer Setup.
The computer supports an interface to an MPEG and TV Video Adapter that
attaches to the rear of the computer. The adapter provides up to 30 fps of
live video or MPEG video to the graphics controller for display on the
LCD, a CRT, or a television. The MPEG and TV Video Adapter and CD-ROM
drive can be used simultaneously.
The audio subsystem is integrated into the system board. The system
supports an internal microphone, stereo speakers, SoundBlaster PRO
compatible audio, CD-ROM audio inputs, an external jack for headphones or
speakers, microphone jack, and line-input jack. Line and CD-ROM inputs and
the speaker outputs are passed through the external options connector and
supported by both expansion bases.
The internal speakers are disabled when the computer is docked in the
expansion base and when headphones or external speakers are installed.
The heart of the audio subsystem is the ESS1688 (ESS688 on Windows 3.1/Dos
6 units) AudioDrive ASIC that provides 16-bit stereo WAV audio, audio
mixing, and FM music synthesis. The entire audio system connects directly
to the ISA bus.
The ESS1688 is OPL3 compatible and compatible with SoundBlaster PRO and
Microsoft Windows Sound System. It can record, compress, and play back
sound and music at 8 or 16 bits up to 44 Khz.
The computer has one PC Card (PCMCIA) controller that supports a Type III
PC card slot that supports either two Type II PC Cards or one Type III PC
Card. A PC card door prevents contamination of the slot. The controller is
Intel ExCA compatible and complies with the Berlin revision of the PCMCIA
standard. The controller supports 5-V cards and all current Compaq PC
Cards. A second PC Card controller is located in both expansion bases.
The diskette drive controller supports 720K, 1.2 MB, and 1.44 MB densities
as well as automatic media detection. Diskette drives can be used in the
computer MultiBay and the expansion bases. When using Windows 95, real
mode drivers must be used for a diskette drive in the expansion base. For
more information see "Solving Diskette and Diskette Drive Problems" in
Chapter 2.
The PC87334 Super I/O contains two UARTs which are fully compatible with
NS15450 and NS16550. Both ports support MIDI baud rates and one port also
supports IrDA and HP SIR compliant signaling protocol. The two serial
ports are configured as one RS- 232C serial port and one infrared (IrDA)
port.
o The standard RS-232 serial port has an 82550 compatible serial
controller. The physical connector is a standard 9-pin D connector. The
interface can be configured as COM1, COM2, COM3, or COM4.
o The infrared communication is implemented with an 82550 compatible
serial controller. The minimum data rate supported by the Infrared Port
is 115K bits per seconds. The interface can be configured as COM1, COM2,
COM3, or COM4.
The parallel port support is integrated into the PC87334 Super I/O. The
computer has one parallel port that can be configured to operate in
compatible mode, enhanced modes 1.7 and 1.9 (EPP), and extended
capabilities (ECP) mode (IEEE-1284 compatible). The default mode is the
compatible mode. The physical connector is a standard 25-pin D connector.
The parallel port interface can be configured as LPT1, LPT2, or LPT3.
When the computer is mounted in either expansion base, the system can
support up to four IDE hard drives. When using two hard drives in the
computer, one of the hard drives is installed in the dedicated hard drive
bay and the other in the MultiBay.
NOTE: The dedicated hard drive bay provides limited support for the Compaq
LTE Elite hard drive. See Appendix C for details.
The hard drive remains powered off from Standby (Suspend) until the first
access occurs. The hard drive is powered off during Standby (Suspend).
The cooling fan is mounted in the system unit on the left side at the
ventilation exhaust port. Functioning as an exhaust fan, it provides air
flow across the electronic components for cooling. The fan plugs into a
2-pin connector on the system board.
The I/O connector panel is an integral part of the system board. In
addition to the I/O panel, the system board supports the following:
o PC card rails and connectors

o Power connector
o External keyboard connector
o All audio connectors except mono microphone jack
Additional MultiBay Expansion Base and MultiBay ISA details are presented
in Section 1.5.
Power Board
The power board is a DC-to-DC converter that provides the required
voltages of +3.3 and +5 volts from one of the power sources (main battery
pack, AC Adapter, or Automobile Adapter).
The power board is provided as a field replaceable unit. To remove and
replace the power board, you must first remove the CPU cover, keyboard,
and processor board. The power board connects to the system board with two
connectors and is secured in place with one screw.
Keyboard
The keyboard is available as an assembly consisting of the following
parts:
o Keyboard
o Keyboard bezel
o Battery release
o MultiBay device release
o EasyPoint II controller
The battery release, MultiBay device release, and EasyPoint II controller
are also available as replaceable units.
To remove the keyboard assembly, the CPU cover must be removed first. The
keyboard ribbon cable (ZIF connector) and EasyPoint II controller cable
must be disconnected. Three screws on the bottom on the system unit and
four screws across the front (inside of the MultiBay and dedicated battery
compartment) must then be removed to release the keyboard.
The battery release mechanism consists of the following parts:
o Battery release actuator
o Battery release spring
o Battery release holder
o Battery release hook
o Battery release hook spring
All of these components are included in the Latches Kit.
The battery release spring maintains the mechanism in the latched state
until the release actuator is pushed. This action retracts the release
hook from the battery. The release hook spring ensures that the battery
hook firmly engages the battery. The battery release holder serves as a
mounting platform for the other release mechanism components. The release
hook and release hook spring are fastened to the release holder with a
screw. The release spring connects the release actuator to the holder. The
holder is held to the bottom of the keyboard with two screws.
The MultiBay device release mechanism is very similar to the battery
release mechanism and consists of the following parts:
o MultiBay device release actuator
o MultiBay release spring
o MultiBay release holder
o MultiBay release hook
o MultiBay release hook spring
o CD-ROM drive release bar
All of these components are included in the Latches Kit.
The MultiBay device release spring maintains the mechanism in the latched
state until the release actuator is pushed. This action retracts the
release hook from the diskette drive or hard drive. Pushing the release
actuator also causes the CD-ROM drive release bar to eject a CD-ROM drive
if one is installed. The release hook spring ensures that the release hook
firmly engages the device in the MultiBay. The MultiBay release holder
serves as a mounting platform for the other release mechanism components.
The release hook and release hook spring are fastened to the release
holder with a screw. The release spring connects the release actuator to
the holder. The holder is held to the bottom of the keyboard with a screw
and standoff.
The EasyPoint II controller supports the mouse buttons and the EasyPoint
II pointing stick. It is mounted to the bottom of the keyboard assembly
directly under the mouse buttons. The CPU cover and keyboard must be
removed to gain access to the controller. Two screws hold the controller
to the keyboard. Once released, the flat cable can be disconnected from
the ZIF connector on the underside of the controller.
MultiBay
The MultiBay accommodates the following devices:
o Dual-speed, quad-speed, or 6x CD-ROM drive
o Second hard drive
o Second battery pack

Chapter 1.7 Design Overview - MultiBay Expansion Base and MultiBay ISA Expansion Base
In addition to replicating the computer I/O panel and offering additional
mass storage device bays, the expansion bases include the following:
o Main board with integrated Ethernet
o MultiBay connector board
o Power supply
o IrDA interface
o Activity lights
o MultiBays with ejectors
o PC Card slots
o ISA expansion board slot (MultiBay ISA Expansion Base model)
o Computer docking mechanism
1.7.1 Main Board
The expansion base main board supports the following major components:
o Ethernet controller (National DP83907)
o PCMCIA controller (Cirrus 6722)
o Super I/O (National 87334)
o Power controller (TMP47P440AF)
The Ethernet controller supports an integrated 10MB/sec Ethernet
subsystem with 10BaseT and 10Base2 interfaces. The Super I/O component
supports the MultiBays.
1.7.2 MultiBay Connector Board
The MultiBay connector board is mounted between the two MultiBays and
serves to route the appropriate signals to the MultiBay connectors.
1.7.3 Power Supply
The power supply is an AC-to-DC converter that serves the same function as
the AC adapter and DC-to-DC converter in the computer. It provides
regulated DC power for all of the subsystems. The expansion base uses a
standard AC power cord that connects directly to the power supply.
An external fan mounted on the power supply provides cooling. When the
temperature of the power supply exceeds 104oF (40oC), the fan turns on.
When the temperature drops below 104oF, the fan turns off.
The MultiBay ISA model has an auxiliary cooling fan mounted on the rear of
the bottom case. The auxiliary fan remains active as long as power is
applied to the MultiBay ISA Expansion Base.
1.7.4 IrDA Interface
The IrDA interface is mounted on the front left corner of the expansion
base and shares a small PCB with the removable drive status lights. The
board is mounted to the underside of the expansion base top cover with a
single screw. The IrDA interface on the expansion base replicates the IrDA
interface on the computer.
1.7.5 Activity Lights
The expansion base has two sets of activity lights.
Removable-Drive Lights
The removable-drive lights are installed on the front left of the
expansion base and share a small PCB with the IrDA interface. The board is
installed as a unit from the back side of the expansion base top cover.
The status lights are identified in Figure 1-7 and described in Table

===========================================================================
1.7.6 MultiBays with Ejectors
Each expansion base has two MultiBays. Each MultiBay is removable as a
unit with its ejector mechanism. The MultiBay is held to the expansion
base cover with three screws. The MultiBays in the expansion base
accommodate the same drives that are used by the computer and can be used
to charge batteries. MultiBay I will accept Compaq LTE Elite hard drives.
1.7.7 PC Card Slots
Each expansion base has two Type III PC Card slots that function similarly
to the PC card slots on the computer. Each PC Card slot on the expansion
base supports one Type I, one Type II, or one Type III PC Card. The only
serviceable part of the PC card slots are the slot doors. The rails and
connectors are incorporated into the main board.
1.7.8 Computer Docking Mechanism
The computer docking mechanism has a lever that protrudes from the right
side of either expansion base and serves to aid in seating the computer
when it is pushed toward the rear of the expansion base. The lever
releases the computer from the expansion base when it is pushed toward the
front of the expansion base.
1.7.9 ISA Expansion Board
The MultiBay ISA Expansion Base provides one slot for an 8- or 16-bit,
full-length industry-standard (ISA) expansion board.
The following provisions must be considered when choosing the type of ISA
expansion board to be installed in the expansion base:
o The enhanced video performance of the Compaq LTE 5000 Family of Personal
Computers drives an external monitor at resolutions up to 1024 x 768 x
256 colors and at selectable refresh rates up to 72 Hz, making the use
of ISA graphics controller boards unnecessary. If an ISA graphics
controller card is installed, the system will not operate. Graphics
controller boards are not supported.
o If a National NE2000 or compatible network ISA board is installed, the
built-in ethernet connectors in the expansion base are disabled. To
re-enable the built-in ethernet network feature, the NE2000 or
compatible network ISA expansion board must be removed.
Two Network Interface Cards (NICs) can be enabled at one time as long as
both are not NE2000 or compatible.
NOTE: NICs that have a default address of 300h require setup
configuration changes because the built-in ethernet uses the 300h
address.
o Some Moving Picture Experts Group (MPEG) ISA boards cannot be installed
as they require connection to the "feature connector" of the graphics
controller. This feature connector is not provided on the MultiBay ISA
Expansion Base. MPEG ISA boards with a standard video port (external
monitor connector) that do not require connection to the feature
connector on the graphics controller should function satisfactorily.
The Compaq MPEG and TV Video Adapter option provides enhanced MPEG
capabilities for use with the Compaq LTE 5000 Family of Personal
Computers. To achieve maximum MPEG functionality support, use the Compaq
MPEG and TV Video Adapter option.
o Due to the vast numbers of ISA expansion boards that are available,
Compaq does not guarantee or support every ISA expansion board.
Refer to the documentation accompanying the ISA expansion board being
installed for complete installation and configuration instructions.
Chapter 2. Troubleshooting
Chapter 2.0 Introduction
This chapter contains troubleshooting information for the computer. The
basic steps in troubleshooting include:
1. Completing the preliminary steps listed in Section 2.1.
2. Running the Power-On Self-Test (POST) as described in Section 2.4.
3. Running the Computer Checkup (TEST) as described in Section 2.5.
4. Performing the recommended actions described in the diagnostic tables
in Section 2.7 if you are unable to exercise POST or Computer Checkup
or if the problem persists after running POST and Computer Checkup.
Adhere to the following guidelines when troubleshooting:
o Complete the recommended actions in the order in which they are given.
o Repeat POST and Computer Checkup after each recommended action until the
problem is resolved and the error message does not return.
o Once the problem is resolved, do not complete the remaining recommended
actions.
o Refer to Chapter 5 for any removal and replacement procedures that are
recommended.
Chapter 2.1 Preliminary Steps
IMPORTANT: Use the AC adapter when running POST, Computer Setup, or

procedure to clear the password:
1. Complete the preparation for disassembly procedures in Section 5.3.
2. Remove the CPU cover as described in Section 5.5.
3. Move the jumper on JP1 (Figure 2-1) from pins 2 and 3 to pins 1 and 2.
4. Turn on the computer and run POST.
5. Turn off the computer and move the JP1 jumper to pins 2 and 3 for
normal operation.
Chapter 2.3 Running Computer Setup
The ROM-based Computer Setup displays the current system configuration and
allows you to set system and power management parameters. These parameters
are stored in CMOS, and a backup copy is saved in a parameter block in
system flash ROM.
You can access Computer Setup by pressing F10 when the prompt appears
after you turn on or restart the computer. The following configuration
parameters can be changed in Computer Setup:
o Date and time
o Power conservation (when)
o Power conservation (level)

o Hibernation on/off
o Hibernation settings
o Warning beep
o Setup password
o Diskette drive disable
o Serial/IrDA ports disable
o Parallel port disable
o PC Card slots disable
o Resume password on/off
o Boot memory test
o Keyboard numlock
o Boot sequence
o Boot display
o Serial port settings
o Infrared port settings
o Parallel port settings
o Power-on password
o Diskette drive boot disable
o NTSC/PAL
o Windows 95 Power Properties
o Lid closure notification
o Advanced LPT mode
Computer Setup automatically recognizes and configures the system for new
Compaq devices. It does this without prompting you for information about
the devices. However, if you add a memory expansion board, the next time
you turn on the computer a prompt appears notifying you of the new memory
configuration.
The first Computer Setup screen displays current settings for the system,
ports, and devices. The status bar at the bottom of the screen gives
instructions for navigating and choosing options. The status bar also
displays descriptions as you highlight menus and menu options.
NOTE: If the main system board is replaced, the serial number on this
screen changes to 0 (zero).
Select one of the menus from the menu bar at the top of the screen to view
or to change the following configuration settings:
o Initialization startup preferences
o Ports, including serial/infrared, parallel, Ethernet, and MPEG
o Power, including Power Management and Hibernation
o Security, including setup and power-on passwords and disabling devices
2.3.1 Initialization Menu
Select the Initialization menu to set the date and time and to change the
initialization (startup) settings for running the POST memory tests,
numlock on or off, the drive boot sequence, boot display, and lid closure
notification.
NOTE: The boot sequence sets the order in which the system searches for a
bootable drive to start the computer. Before changing the booting
sequence, see "The Hard Drive Boot Sequence" in Appendix C for more
information.
2.3.2 Ports Menu
Select the Ports menu to change the default input/output (I/O) addresses
and interrupt requests (IRQs) for serial/infrared, parallel, and Ethernet
ports, select PAL or NTSC for the optional MPEG video format, and enable
Advanced LPT mode.
NOTE: If you select conflicting settings for the ports, the system
automatically changes one of the settings.
2.3.3 Power Menu
Select the Power menu to enable or disable Power Management, PC Card slot
power management (not available on LTE 5000, LTE 5100, and LTE 5200
models), low-battery warning beeps, and an external energy saving monitor.
The factory default settings are:
o Power Management Enabled While on Battery
o Conservation Level Medium
o Low-Battery Warning Beeps Enabled
o External Energy Saving Monitor Disabled
o PC Card Power Off During Standby
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CAUTION <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
If you disable Power Management or Hibernation, you must take immediate
action to resolve a low-battery condition to prevent losing unsaved
information.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>><<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
If you select to disable the low-battery warning beeps, a low-battery
condition is indicated only by a blinking battery light. If you disable
Power Management or Hibernation, information in memory is not
automatically saved during a critical low-battery condition.
If you enable the selection for an external energy saving monitor, it
enters low-power mode when the screen timeout occurs. If you enable this
selection and you do not have an energy saving monitor, the screen display
may become distorted.
Under PC Card slot power management, resume power to the PC Card slots and
ring reserve feature may be enabled during Standby (Suspend). This feature
is not available on the LTE 5000, LTE 5100, and LTE 5200 models.
Under Power Management, you can select whether to enable Power Management
while on AC or battery power, only while on battery power, or never
(disabled).
If you enable Power Management, you can select the conservation level:
high, medium, or custom. The conservation level sets the timeouts for
Standby (Suspend), Hibernation, drives, and screens.
A timeout is a period of inactivity after which power is turned off to the
system or component. Refer to Chapter 7 for more information about Standby
(Suspend) and Hibernation.
o High: - Provides the maximum amount of power conservation and the
maximum battery operating time from a single charge.
o Medium (default): - Provides a balance between performance and battery
life.
o Custom: - Conserves power according to specified timeout settings.
NOTE: Selecting to disable the infrared port under the Security menu also
conserves power.
Windows 95 Power Properties
To open the Windows 95 Power Properties dialog box, double click the Power
icon in Control Panel. Windows 95 provides the following options:
o Advanced (default) - Activates power management settings in Computer
Setup and provides some additional power-saving features.

o Restore Factory Defaults: Replaces the current configuration settings
with the original factory default settings.
Chapter 2.4 POST Error Messages
This chapter contains typical error messages that you may encounter during
the power-on self-test (POST). POST is a series of tests that run every
time you turn on the computer. POST verifies that the system is configured
and functioning properly. A successful POST is followed by one or two
short beeps.
If you receive an error message listed below, follow the recommended
action. If you receive an error message that is not listed, contact your
Compaq authorized service provider. You may also want to run Computer
Checkup from the Diagnostics diskette. Information about running Computer
Checkup is presented later in this section.
If POST detects an error, one of the following events occurs:
o A message with the prefix "WARNING" appears informing you where the
error occurred. The system pauses until you press F1 to continue.
o A message with the prefix "FATAL" appears informing you where the error
occurred. After the message, the system emits a series of audible beeps.
The system then stops.
o The system emits a series of audible beeps. The system then stops.
Warning messages indicate a potential problem exists such as a system
configuration error. When F1 is pressed, the system should resume. You
should be able to correct problems that produce WARNING messages.
IMPORTANT: When a WARNING message includes the prompt to "RUN SCU," run
Computer Setup. (Computer Setup replaces the SCU utility.)
Fatal errors emit a beep and may display a FATAL message. Fatal errors
indicate severe problems, such as a hardware failure. Fatal errors do not
allow the system to resume. Some of the Fatal error beep codes are listed
at the end of this section.
