							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 fan is integrated into the input/output (I/O) bracket/fan assembly. To
replace the fan, the I/O bracket/fan assembly must be replaced.

							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.
Hard drive security clips can be installed to prevent the hard drive from
being removed (refer to Section 4.12). When the security clips are
installed, a lock label should be attached to the front of the hard drive
to indicate that the drive is locked in place. The computer must be
partially disassembled to remove the security clips before the hard drive
can be removed.
NOTE: The Compaq Diagnostics utilities (which include Computer Setup)
reside in a hidden partition on the Compaq LTE Elite hard drive (not
in the ROM). There is no preinstalled software on a new spare hard
drive. When installing a new spare hard drive, the hidden partition
must be created, the diagnostics utilities must be installed, and the
C: partition must be formatted before restoring any data
(Section 4.12). On the option kit hard drives, the hidden partition 
						

							is already created and the diagnostics utilities are already 
installed.
IMPORTANT: The hard drive must be handled with care. Refer to the cautions listed in Section 4.12.
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]. The color STN display assembly has two
externally adjustable control slides: one for contrast [2] and one for 
brightness [3]. The display assembly comes with one of the following 
panels, depending on the model: 
o 9.5-inch color STN 
o 9.5-inch mono TFT 
o 8.4-inch color TFT 
o 9.5-inch color TFT 
IMPORTANT: In order to optimize display quality and ensure regulatory compliance, many of the parts in the 9.5-inch color TFT display 
can be  replaced  only  by  repla cing  the  entire  display  assembly  (Section 4.9). 
						

							Refer to Section 5.4 for display specifications. 
NOTE: A certain number of pixels in the display panel are allowed to benonfunctional 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. The slot accommodates one of the following card 
combinations: 
o Two PCMCIA Type I or Type II cards 
o One PCMCIA Type III card 
The PCMCIA slot supports both 5 volt and 3.3 volt PCMCIA cards in 
accordance with PC Card Standard Release 2.1 or later and the Exchangeable
Card Architecture (ExCA) Specification 1.10. 
						

							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. Call Compaq Reseller Support to have a copy of the
list faxed to you.
1.7 Docking Options 
The Compaq LTE Elite docks with the following options (Figure 1-16):
o Compaq SmartStation expansion base
o Compaq LTE Lite Desktop Expansion Base (with an Upgrade Adapter)
o Compaq MiniStation/EN and MiniStation/TR convenience bases
Refer to Appendix D for more information on docking and undocking.
1.8 Running Computer Setup 
The Computer Setup utility resides in a hidden partition on the hard drive. 
						

							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. A low battery
condition could initiate Standby and interrupt the program.
To run Computer Setup, complete the following steps:
1. Turn on or restart the computer.
2. Press the F10 key as soon as the cursor moves to the upper-right corner
of the screen.
3. When prompted, select the desired language.
4. Select Computer Setup from the Configuration and Diagnostics menu.
5. Follow the instructions on the screen.
1.9 Reprogrammable Flash ROM 
The flash ROM can be reprogrammed to update system firmware and provide the
most recent level of system functionality. In some cases, problems may be
solved by upgrading the ROM.
Erase and reprogram the nonvolatile read only memory (ROM) by using the
ROMPaq utility. The ROMPaq utility is available on the Portables ROMPaq
Upgrade Diskette, which includes on-screen instructions for implementing
the flash ROM upgrade (Table 3-16).
1.10 Power Management 
The following power management features are available for conserving AC
power and extending battery operating time:
o Advanced Power Management (APM)
o Power management settings
o Standby
o Hibernation
Advanced Power Management (APM)
APM is installed on the computer and requires no action from the user to
reduce power consumption. APM turns off the processor between keystrokes 
						

							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. A timeout is
specified period of system or component inactivity. After this period, the
system or component (for example, the hard drive) is shut down to conserve
power until it is accessed again.
If the power conservation rate and timeouts are not selected, the computer
uses the default settings listed in Table 1-3.
Table 1-3. Power Conservation Default Settings
===========================================================================
Battery Power AC Power
Feature Default Setting Default Setting
===========================================================================
Standby timeout 5 minutes 15 minutes
Hard drive timeout 2 minutes 15 minutes
Screen save timeout 3 minutes 15 minutes
Display brightness 75% of rated brightness 100% of rated brightness
Processor speed (MHZ) 100% of rated speed 100% of rated speed
===========================================================================
Standby 
						

							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).
When the user exits Standby (by pressing the standby button again),
information returns to the screen at the point where Standby was initiated.
Under battery power, the computer can maintain Standby for up to 120 hours.
NOTE: The computer cannot initiate Standby under the conditions listed
above when docked in an expansion base or a convenience base. In
addition, the computer cannot initiate Standby if there is activity
from the hard drive, diskette drive, mouse, keyboard, PCMCIA slot,
parallel connector, or serial connector.
