Chapter 4.2 Service Considerations 
Listed below are some of the considerations that you should keep in mind
during the disassembly and assembly of the computer.
4.2.1 Tool and Software Requirements
To service the computer, you need the following:
o Torx T-8 screwdriver 
						

							o 3/16-inch nut driver (for screwlocks and standoffs)
o Connector removal tool
o Display bezel removal tool
o Diagnostics software
4.2.2 Screws
The screws used in the computer are not interchangeable. If an incorrect
screw is used during the reassembly process, it can damage the unit.
Compaq strongly recommends that all screws removed during disassembly be
kept with the part that was removed, then returned to their proper
locations.
IMPORTANT: As each subassembly is removed from the computer, it should be
placed away from the work area to prevent damage.
4.2.3 Cables and Connectors
Cables must be handled with extreme care to avoid damage. Apply only the
tension required to seat or unseat the cables during insertion or removal
from the connector. Handle cables by the connector whenever possible. In
all cases, avoid bending, twisting, or tearing the cables, and ensure that
the cables are routed in such a way that they cannot be caught or snagged
by parts being removed or replaced.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CAUTION >>>>>
						

							The computer uses a zero insertion force (ZIF) connector for the keyboard
cable to the system board. To remove a cable from a ZIF connector, lift
both corners of the ZIF connector slide simultaneously with constant light
force. Then remove the cable (Figure 4-1).
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CAUTION >>>>>
						

							Chapter 5. Computer Removal and Replacement Procedures 
 
Chapter 5.0 Introduction 
This chapter presents the removal and replacement procedures for the
computer.
Chapter 5.1 Serial Number 
The computer serial number should be reported to Compaq when requesting
information or ordering spare parts. The serial number is displayed
immediately above the serial connector on the rear of the computer
(Figure 5-1).
Chapter 5.2 Disassembly Sequence Chart 
Use the chart below to determine the section number and disassembly
sequence for removing components from the computer. 
						

							Chapter 5.3 Preparing the Computer for Disassembly 
Before beginning removal and replacement procedures, complete the
following procedures:
1. Undock the computer from the expansion base (Section 5.3.1).
2. Disconnect AC power and any external devices (Section 5.3.2). 
						

							3. Remove the battery pack(s) (Section 5.3.3).
4. Remove the auxiliary battery (Section 5.3.4).
5. Remove the hard drive (Section 5.3.5).
6. Remove the battery or mass storage device from the MultiBay (Section
5.3.6).
7. Remove any PC cards (section 5.3.7).
NOTE: It is important that these instructions be followed when replacement
of any part requires removal of the display assembly:
Slide the display assembly back in place and replace all screws. The
screws must be fully tightened to ensure that they do not touch the
expansion base sensor located near the left hinge. Failure to properly
seat the screws may prevent the unit from booting up.
5.3.1 Undocking the Computer
If the computer is not docked in an expansion base, proceed to Section
5.3.2. If the computer is docked in an expansion base, see Figure 5-3 and
complete the following steps to undock the computer:
1. Turn off the power [1] to the expansion base.
2. Pull the docking lever forward [2] to release the computer and lift the
computer out of the expansion base. 
						

							5.3.2 Disconnecting the Computer
If the computer is docked in an expansion base, see Section 5.3.1 for
undocking instructions. If the computer is not docked in an expansion
base, see Figure 5-4 and complete the following steps to disconnect the
computer:
1. Turn off [1] the computer.
2. Disconnect the AC Adapter power cord from the wall outlet [2].
3. Disconnect the AC Adapter [3] from the computer. 
						

							4. Turn off and disconnect any external devices.
5.3.3 Battery Pack
The battery pack should be removed before performing any internal
maintenance on the computer.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> WARNING >>>>>>
						

							Removing the Battery Pack
To remove the battery pack, see Figure 5-5 and complete the following
steps:
1. Slide the battery release actuator [1] toward the front of the
computer.
2. Slide the battery pack [2] out of the battery bay.
Installing the Battery Pack
To install a battery pack, complete the following steps:
1. Insert the battery pack, with the label facing up and the battery
contacts facing the inside of the bay.
2. Push firmly on the battery pack; it will lock into place.
Using the Battery Pack as a Counterweight
With the display open and the mass storage devices and battery pack
removed from the computer bays, the weight of the display makes the
computer susceptible to being easily tipped over. When performing service 
						

							that does not require the display to be removed, you can use the battery
pack as a counterweight to stabilize the computer.
To use the battery pack as a counterweight, complete the following steps:
1. Slide the battery panel all the way to the right.
2. Insert the battery pack into the battery compartment (Figure 5-6). The
battery panel prevents the battery from making electrical contact.
5.3.4 Auxiliary Battery
The auxiliary battery is stored in a compartment on the bottom of the
computer (Figure 5-7). The auxiliary battery should be removed prior to
servicing the computer.
Removing the Auxiliary Battery
To remove the auxiliary battery, complete the following steps:
1. Using a small flat-blade screwdriver to release the door clips [1],
remove the auxiliary battery compartment door [2] (Figure 5-7).
