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...

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.
Refer to Appendix B for information on increasing battery pack operating
time, ensuring battery gauge accuracy, conditioning the battery pack, and...

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.

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...

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...

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...

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

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...

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...
