Memory Expansion Board The 4 or 8 MB base RAM memory (depending on the model) may be increased by adding an optional memory expansion board (Figure 1-9). The memory expansion board plugs directly into the back side of the system board (Section 4.
o 4 MB o 8 MB o 16 MB NOTE: Some early memory expansion boards for the Concerto Family of Personal Computers (option kit numbers 144790-001 and 144790-002) operate at 80 ns and do not function properly when installed in the Compaq LTE Elite Family of Personal Computers, which operate at 70 ns. Use only Compaq LTE Elite memory expansion boards (Table 3-2). Refer to the table in Section 5.3 for a list of total RAM memory based on available system memory and memory obtained from the expansion board.
The internal fan (Figure 1-11) draws in fresh air through vent holes in the PCMCIA compartment door, then exhausts it out the back of the computer. The fan operates on 5 volts and is controlled by temperature sensors located near the internal power supply and the processor board. The fan is designed to turn on automatically when the system approaches maximum reliable operating temperatures (refer to "Temperature Sensors" in this section).
The removable internal nickel metal hydride (NiMH) battery pack connects to the computer through a set of battery contacts mounted on the system board. Battery charging functions are controlled by the DC-to-DC converter on the system board. The battery pack contains RAM memory that saves the last recorded battery operating time and battery fuel gauge values.
memory for a one-minute period during Standby to allow a battery pack to be replaced. The auxiliary battery has a nickel cadmium cell that supplies 7.2 volts for 50 mAmp hours. The auxiliary battery recharges when the computer is on while connected to an external power source or the battery pack. It takes approximately 10 hours to recharge a fully discharged auxiliary battery using AC power and approximately 20 hours to recharge it using the battery pack.
The 2.5-inch hard drive (Figure 1-13) is user-removable from the front of the computer (Section 4.12). The hard drive release button allows the drive to be removed without disassembling the computer. A connector on the hard drive enclosure mates to a connector on the system board. NOTE: The hard drive may have either a metal handle (Figure 1-13) or a plastic pull tab that is attached directly to the hard drive enclosure.
is already created and the diagnostics utilities are already installed. IMPORTANT: The hard drive must be handled with care. listed in Section 4.12. Refer to the cautions Display Assembly The display assembly (Figure 1-14) is connected to the system unit by clutches, a display cable and a ground cable. The display assembly includes an integrated trackball board and an inverter board. The color and black-and-white TFT display assemblies have an externally adjustable brightness control slide [1].
Refer to Section 5.4 for display specifications. NOTE: A certain number of pixels in the display panel are allowed to be nonfunctional due to limitations in LCD technology. PCMCIA Slot The PCMCIA connector is mounted to the system board. The connector is accessible through the PCMCIA slot [1], (Figure 1-15), which is covered by a PCMCIA compartment door.
NOTE: PCMCIA stands for Personal Computer Memory Card International Association. PCMCIA standards continue to change. Many cards on the market do not comply with the PCMCIA specifications and, therefore, do not function properly in the computer. To assist users in selecting compatible PCMCIA devices, Compaq provides a list of third-party cards that have been tested in Compaq products. To ensure compatibility, select a Compaq PCMCIA modem or other vendor cards on the tested list.
Run Computer Setup for the following situations: o To configure options o To update alarm, time, date, or password information NOTE: Alarm, time, and date information can be lost if the computer is unused for approximately 60 days without charging the internal battery pack or without AC power being connected (refer to "Auxiliary Battery" in Section 1.6). If this information is lost, run Computer Setup to restore it. IMPORTANT: Use AC power during Computer Setup procedures.
and when the system is idle. This function is transparent to the user. APM also provides occasional screen messages about the battery while in the Windows environment (for example, low power condition). Power Management Settings You can select power conservation settings through Computer Setup, Power Management, or by pressing the Fn + F7 hotkeys to maximize power for specific requirements. These settings control the power conservation rate and the timeout values for various system components.
Standby is a power conservation mode for battery or AC power operation during which most of the components (e.g, hard drive, processor, display) shut down. The computer initiates Standby under the following conditions: o When the user presses the standby button [1] (Figure 1-17). o After a timeout occurs. o When the battery pack voltage reaches a low level (if this option is preselected).
Hibernation Hibernation is a power conservation mode that performs the following functions: o Locks the keyboard and clears the screen. o Saves all current information in memory and the place in the application to the hard drive. o Turns the computer off. Hibernation is preenabled on the computer and the Hibernation file is preinstalled on the hard drive. The Hibernation file is slightly larger than the total RAM memory of the computer (system memory and memory expansion board).
1.11 Security The computer has the following security features: o Power-on password and setup password. o The ability to disable certain components, such as the keyboard, diskette drive, display, PCMCIA slot, parallel connector, and serial connector, to prevent unauthorized access. o Provision for an optional cable lock (Figure 1-18) to lock the computer to an immovable object. NOTE: For procedures to clear the power-on password, refer to "Clearing the Power-On Password" in Section 2.1.
Chapter 2 - Compaq LTE Elite Troubleshooting Introduction This chapter covers troubleshooting information for the computer. The basic steps in troubleshooting include: 1. Following the preliminary steps listed in Section 2.1. 2. Running the Power-On Self-Test (POST) as described in Section 2.2. 3. Running Computer Checkup (TEST) as described in Section 2.3. 4. Following the recommended actions described in the diagnostic tables in Section 2.
5. Disconnect any external devices that you do not want to test. (Do not disconnect the printer if you want to test it or use it to log error messages.) NOTE: If a problem only occurs when an external device is connected to the computer, the problem may be with the external device or its cable. Verify this by running POST with and without the external device connected. 6. Install loopback plugs in the serial and parallel connectors if you would like to test these ports (Table 3-13). 7.

11. Connector for docking mechanism motor 12. All pass-through I/O connectors 13. A/B switch 14.
The battery charger [1] (Figure 6-8), controlled by the system board, charges a Compaq LTE Elite spare battery pack. The battery charger operates whenever the expansion base is connected to an electrical outlet, whether the expansion base is on or off. In addition to charging the spare battery pack in the battery charger, the expansion base simultaneously charges the battery pack in the docked computer, whether the system is on or off.
circuits: o Main expansion base circuit (+/- 5 volts, +/- 12 volts) o VBatt1 circuits (10 to 18.5 volts) o VBatt2 circuits (10 to 18.5 volts) The outputs to the above circuits are located on an edge card connector in the power supply. The vertical circuit board plugs into this edge card connector to distribute power to the unit. Refer to Appendix A for pin assignments for the power supply output connector. Figure 6-9 illustrates the function of the power supply output circuits.
VBatt1 Circuits The VBatt1 circuits provide 10 to 18.5 volts to the following: o Computer (while docked) o Docking mechanism VBatt2 Circuits The VBatt2 circuits provide 10 to 18.5 volts to the following: o Battery charger in expansion base o Voltage regulator on the expansion base system board, which converts 18.5 volts to 5 volts for the microcontroller, sensors, and wiring harness. NOTE: The microcontroller controls the VBatt2 circuits.
The expansion base has a motorized docking mechanism (Figure 6-10) that docks and undocks the computer. The mechanism uses a sled apparatus; draw hooks on the sled mate with notches in the bottom of the computer. The mechanism does not operate if the unit is locked with a key or if a sensor detects an undesirable condition such as an open PCMCIA door when a request to undock is made.
The expansion base has a two-part computer status sensor [1] (Figure 6-11) on the docking mechanism sled. This sensor corresponds to two sense pads on the bottom of the Compaq LTE Elite [2] or the bottom of a SmartStation Adapter when connected to a Compaq LTE Lite. The computer status sensor/sense pad combination indicates whether the computer is on, off, or in Standby. The expansion base uses this information to determine if the computer should be allowed to dock/undock.
6. Edge card connection to the power supply 7. Edge card connector to the system board 8. Configuration switches for optional drives In addition, the circuitry for the expansion base registers and hard drive decode are on the vertical circuit board. Configuration Switches The configuration switches [8] (Figure 6-12) are accessible when the bottom cover is removed. The configuration switch settings are listed on a label on the bottom of the drive cage in drive position 1 (Figure 6-14).
IMPORTANT: Skirted expansion boards cannot be installed in the expansion board connector that is next to the drive cable connectors [5] (Figure 6-13).
The expansion base has two half-height drive cages for installing internal drive options in the drive bays. The expansion base comes from the factory with blank panels that cover the drive bay openings. The drive bays are designated as drive positions 1 and 2 [1], [2] (Figure 6-14). To be supported in the expansion base, drives must meet the power requirements in Section 10.2, and the dimension requirements in Section 10.1. Refer to Appendix C to configure the system for drives other than SCSI-2.
"backplane board") and the system board (also known as the "interconnect board") each have a printed description of where the drive cables connect. Each drive cable also has a printed description, a Compaq spare part number, and a Compaq assembly part number. Refer to Section 9.15 for more information on drive cable locations.
replaced separately using parts from the Miscellaneous Small Mechanical Parts Kit (Table 8-8). NOTE: The eject switch board is integrated into the eject switch cable harness. To replace the eject switch board, the eject switch cable harness must be replaced (Section 9.17). Keylock Switch The keylock switch [2] (Figure 6-15) is connected to the eject switch cable harness.
Keylock Assembly and Override Blocker The keylock assembly [1] and override blocker [2], located in the bottom cover, work together to provide system security (Figure 6-16). The keylock assembly mechanically locks the bottom and top cover of the expansion base together and closes the keylock switch. When closed, the keylock switch electronically disables the docking mechanism (to prevent unauthorized docking and undocking of the computer).
The keylock assembly is replaceable. The blocker is integrated into the bottom cover. To replace the blocker, the bottom cover must be replaced. NOTE: In addition to the keylock assembly, the expansion base is designed with a provision for an optional cable lock to secure the expansion base to an immovable object (Section 6.9).
Two horizontal guides [1] located at the front of the docking bay (Figure 6-17) help align the computer in the expansion base. The horizontal guides engage in the grooves that are located between the upper and lower halves of the computer [2]. The guides also prevent the computer from being vertically removed while it is docked in the expansion base to prevent damage to the connectors and to provide additional security. 6.

Appendix B - Battery Pack Operating Time Introduction This appendix covers the following information concerning battery pack operating time: o o o o Increasing battery pack operating time Ensuring battery gauge accuracy Conditioning a battery pack Disposal of a used battery pack B.1 Increasing Battery Pack Operating Time Battery pack operating time differs depending on several variables.
o Set the power conservation levels in the Power Management utility to "High." o Customize the timeout values to work more efficiently with the applications. The amount of battery life depends on the values selected. Maximizing the Energy Stored To maximize the energy stored in the battery pack, follow these guidelines: o Condition the battery pack at least every 60 days to improve overall battery performance and ensure the continued accuracy of the battery gauge.
By pressing the Fn+F8 hotkeys, the battery gauge window displays the operating time and percentage of battery power remaining (Figure B-1). The battery gauge can be displayed when operating the computer under battery power or AC power. The time remaining on the battery gauge varies depending on the power requirements of any applications currently being used, and options currently installed. NOTE: When the power cord is connected to an external outlet, the battery gauge displays a power cord plug symbol.
9. Use the Fn+F7 hotkeys to reset the power conservation level. It takes approximately 1 hour to fast charge the battery pack if the computer is turned off, and approximately 1 1/2 to 2 hours if the computer is being used. NOTE: The battery pack can be charged in the computer, the battery charging compartment in the expansion base, or the battery fastcharger option (Table 3-14). B.
Appendix C - Configuring the System for Optional Drives in SmartStation Introduction This appendix covers configuring the system for optional drives (other than SCSI-2) that are installed in the Compaq SmartStation and includes the following: o Configuring an IDE hard drive o Setting configuration switches for a diskette, tape or an IDE hard drive o Changing the A/B and C/D logical drive designations o Installing EXTDISK.
IMPORTANT: If the expansion base has one IDE hard drive, set the drive jumpers to the "single" drive position. If the drive does not have a "single" position, set the jumpers to "master." Do not set the jumpers to the "slave" position unless a second IDE drive in the expansion base is set to "master." Refer to the drive manufacturer's instructions for information on how to set the jumpers and other important installation instructions. 2. Install the hard drive (Section 9.15). 3.
10. Format the hard drive using the MS-DOS FORMAT command. Enter FORMAT D: IMPORTANT: When formatting an IDE drive that will be used as a bootable drive, add the /S switch to the FORMAT command so that you can use the C/D drive selection switch. Enter FORMAT D:/S 11. If the C/D switch on the vertical circuit board is enabled (the default), set the C/D drive selection switch to operate the hard drive in the expansion base as logical drive C or D. (The default position is D.) 12.
Set the configuration switches to correspond with the new drive configuration and whether you want to disable the A/B and/or C/D drive selection switches. The configuration switch settings are listed in Table C-1 and are also listed on a label on the bottom of the drive cage in drive position 1. Table C-1.
=========================================================================== NOTE: Switch number 6 can be turned off to deactivate the keylock switch and most of the sensors for troubleshooting purposes. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CAUTION <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< Be sure to turn configuration switch number 6 back on when troubleshooting is complete to avoid possible data loss or damage to the system that may occur during docking or undocking.
To change the A/B drive designations, set the new switch position before turning on the computer. Designating Logical Drive C When a Compaq LTE Elite is docked, the C/D drive selection switch sets an optional IDE hard drive in the expansion base to operate as logical drive C (the boot drive) or as logical drive D. The default position is D (the hard drive in the expansion base is D).

Appendix E - Electrostatic Discharge Introduction This appendix covers the proper methods for grounding and the use of recommended materials and equipment for preventing damage from electrostatic discharge (ESD). A sudden discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or micro circuitry. Often the spark is neither felt nor heard, but damage occurs.
o To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes. o Protect all electrostatic parts and assemblies with conductive or approved containers or packaging. o Keep electrostatic sensitive parts in their containers until they arrive at static-free stations. o Place items on a grounded surface before removing them from their container. o Always be properly grounded when touching a sensitive component or assembly.
Grounding Workstations To prevent static damage at the workstation, use the following precautions: o Cover the workstation with approved static-dissipative material. Provide a wrist strap connected to the work surface and properly grounded tools and equipment. o Use static-dissipative mats, heel straps, or air ionizers to give added protection. o Handle electrostatic sensitive components, parts, and assemblies by the case or PCB laminate. Handle them only at static-free workstations.
o o o o o o o o o o o o o o o o o Antistatic tape Antistatic smocks, aprons, or sleeve protectors Conductive bins and other assembly or soldering aids Conductive foam Conductive table-top workstations with ground cord of 1 megohm resistance Static dissipative table or floor mats with hard tie to ground Field service kits Static awareness labels Wrist straps and footwear straps providing 1 megohm +/-10% resistance Material handling packages Conductive plastic bags Conductive plastic tubes Conductive tote bo
Appendix F - Connecting and Configuring Optional SCSI-2 Devices Introduction This appendix contains guidelines for using SCSI-2 (small computer system interface-2) devices, and explains how to connect external SCSI-2 devices, install an internal SCSI-2 drive in the Compaq SmartStation, and install SCSI-2 device drivers.
must install or remove according to your configuration. 4. External cables must be a minimum of 1 foot in length (0.3 meters). The combined length of SCSI-2 cables in a chain must not be longer than approximately 20 feet (6 meters). 5. Generally, each SCSI-2 device requires a software driver. 6. Most SCSI-2 drivers require that their associated device be turned on during startup to recognize the device. Therefore, turn on external SCSI-2 devices before turning on the expansion base. F.
F.3 Changing The SCSI-2 Ddefault Configuration By default, the integrated SCSI-2 controller has the configuration settings listed in Table F-1. To adjust the default settings, refer to the Compaq EZ-SCSI Software Reference Guide. Table F-1.
Parity: When the Parity feature is enabled, the controller checks the parity of received data from the SCSI-2 bus. The controller always generates parity when transmitting data onto the SCSI-2 bus. Disconnect: When the Disconnect feature is enabled, the controller overlaps communications across the SCSI-2 bus. The controller can request operation from multiple SCSI-2 devices in parallel, increasing overall bus performance.
1. Install the SCSI-2 drive (Section 9.15). 2. Connect the SCSI-2 signal and power cables (Figure F-2) as follows: - Connect one end of the SCSI-2 signal cable [1] to the connector on the system board. - Connect the other end [2] to the connector on the rear of the drive. - Connect the outside connector of the drive power cable [3] to the connector on the rear of the drive. - Be sure that the other end of the drive power cable [4] is connected to the vertical circuit board.
5. Install the SCSI-2 drivers to allow the computer to recognize the SCSI-2 drive in the expansion base (Section F.6). 6. If you installed a SCSI-2 hard drive, format and partition the drive. Refer to the Compaq EZ-SCSI Software Reference Guide for additional information. 7. Reboot the computer by pressing the Ctrl+Alt+Delete keys to integrate the new information. 8. If the computer does not automatically reconfigure the system when you turn it on, run Computer Setup ( Section 6.7). 9.
The SCSI drivers enable the computer to communicate with optional SCSI-2 devices. For detailed information about the SCSI-2 drivers and utilities, refer to the Compaq EZ-SCSI Software Reference Guide. IMPORTANT: To ensure that the computer recognizes a SCSI-2 device and installs all necessary drivers, turn on the device before turning on the computer and ensure that the device is turned on when you install the device drivers.
