							Appendix B - Battery Pack Operating Time 
 
Introduction 
This appendix covers the following information concerning battery pack
operating time:
o Increasing battery pack operating time
o Ensuring battery gauge accuracy
o Conditioning a battery pack
o Disposal of a used battery pack
B.1 Increasing Battery Pack Operating Time 
Battery pack operating time differs depending on several variables. To
avoid unnecessary replacement, consider the following variables when
determining how long a charged battery pack should last:
o Power management settings
o Hardware configuration
o Software applications
o Installed options
o Display brightness
o Hard drive usage
o Changes in operating temperature
o Type and number of installed PCMCIA cards
NOTE: The power consumption requirements for PCMCIA cards vary widely. Some
cards drain the battery pack very rapidly.
Table B-1 shows battery pack operating times by model based on worst to
best case.
Table B-1. Battery Operating Time
===========================================================================
Computer Hours
===========================================================================
LTE Elite 4/75CX 2.5 - 4.0 hr
LTE Elite 4/50CX 2.5 - 4.5 hr
LTE Elite 4/40CX 2.5 - 5.0 hr
LTE Elite 4/50E 3.0 - 5.5 hr
LTE Elite 4/40C 3.0 - 5.5 hr
===========================================================================
Battery pack operating time can be increased by as much as 50% by
controlling the energy required by the computer and the energy stored in
the battery pack.
Minimizing the Energy Required
To minimize the energy required by the computer, practice the following: 
						

							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.
o Keep a battery pack in the computer when using it with AC power to supply
the battery pack with a constant trickle charge.
o Store the battery pack in a cool, dry place when not in use.
B.2 Ensuring Battery Gauge Accuracy  
						

							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.
If question marks are displayed in the battery gauge, it means that the
gauge is no longer accurate. To restore the accuracy of the battery gauge
condition the battery pack.
B.3 Conditioning A Battery Pack 
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CAUTION >>>>>
						

							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.4 Disposal Of A Used Battery Pack 
In the interest of safeguarding our environment, Compaq Computer
Corporation recommends that nickel metal hydride (NiMH) and nickel cadmium
(NiCad) battery packs be recycled. Battery packs should be handled in
accordance with country, state, province, or local regulations.

							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.SYS on the Compaq LTE Lite
NOTE: Refer to Appendix F to configure the system for optional SCSI-2
devices.
If you are installing an IDE hard drive, follow the procedures in Section
C.1 to configure the system. If you are installing an IDE hard drive in an
expansion base that will dock a Compaq LTE Lite, install the EXTDISK.SYS
file as described in Section C.4.
If you are installing a diskette drive, set the configuration switches as
described in Section C.2 and read the information on changing the A/B drive
designations in Section C.3.
If you are installing a tape drive, set the configuration switches as
described in Section C.2 and install the tape utility as described in the
documentation included with the tape drive.
C.1 Configuring An IDE Hard Drive 
The Compaq SmartStation has its own interface for an integrated drive
electronics (IDE) hard drive. A hard drive installed in the expansion base
operates on a separate IDE adapter from the one used by the hard drive in
the computer.
IMPORTANT: MS-DOS 6 or higher (5.0 or higher as published by Compaq) is
required to use an optional IDE hard drive in the Compaq
SmartStation. When using a previous version of MS-DOS, the
computer will not recognize the optional IDE hard drive in the
Compaq SmartStation.
To configure the system for an IDE hard drive, complete the following
steps:
1. Before installing the drive, ensure that the master/slave/single
jumpers on the drive are set correctly. 
						

							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 manufacturers instructions for
information on how to set the jumpers and other important
installation instructions.
2. Install the hard drive (Section 9.15).
3. While the bottom cover is off the expansion base, set the configuration
switches on the vertical circuit board to reflect the number and kinds
of drives installed (drive configuration) and whether you want to
disable the C/D switch. Refer to Section C.2 for information on the
configuration switches and to Section C.3 for information on the C/D
switch.
4. Replace the bottom cover (Section 9.6) and turn the expansion base
right side up.
5. If configuration switch number 5 is enabled (the default), ensure that
the C/D drive selection switch is set to the D (default) position.
6. Turn the system off with the power switch, then on again to integrate
the selected configuration and C/D switch settings.
7. When using a Compaq LTE Lite, install the EXTDISK.SYS external device
driver to allow the computer to recognize the IDE hard drive in the
expansion base (Section C.4).
NOTE: The Compaq LTE Elite does not require the EXTDISK.SYS driver.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CAUTION >>>>>
						

							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. Turn the system off with the power switch, then on again to integrate
the new information.
13. If the computer does not automatically reconfigure the system when you
turn it on, run Computer Setup (Section 6.7).
14. Run Computer Checkup to ensure that the drive is working properly
(Section 2.3).
C.2 Setting The Configuration Switches 
The configuration switches on the Compaq SmartStation vertical circuit
board (Figure C-1) must be set when a diskette drive, tape drive, or IDE
hard drive is installed in the expansion base. The six configuration
switches are accessible when the bottom cover is removed. However, you may
have to remove optional expansion boards to gain access.
