REMOVAL AND REPLACEMENT
PROCEDURES
This chapter provides removal and replacement assembly procedures for the Compaq Aero 8000
H/PC Professional.
1.1 Electrostatic Discharge
A discharge of static electricity from your body or other conductor may damage system boards or
other electrostatic-sensitive devices. This type of damage may reduce the life expectancy of the
devices.
1.1.1 Preventing Electrostatic Discharge
To prevent electrostatic damage, observe the following precautions:
„#Avoid hand contact by transporting and storing products in electrostatic-safe containers.
„#Keep electrostatic-sensitive parts in their containers until they arrive at electrostatic-free
workstations.
„#Place parts on a grounded surface before removing them from their containers.
„#Avoid touching pins, leads, or circuitry.
„#Always be properly grounded when touching an electrostatic-sensitive component or
assembly.
1.1.2 Grounding Methods
There are several methods for grounding. Use one or more of the following methods when handling
or installing electrostatic-sensitive parts.
„#Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis.
Wrist straps are flexible straps with a minimum of 1 megohm +/- 10 percent resistance in the
ground cords. To provide proper ground, wear the strap snug against the skin.
„#Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both
feet when standing on conductive floors or dissipating floor mats.
„#Use conductive field service tools.
„#Use a portable field service kit with a folding, electrostatic-dissipating work mat.
✎If you do not have the suggested equipment for proper grounding, or if you need more
information on static electricity or assistance with product installation, contact a Compaq
authorized service provider.

1-2 Removal and Replacement Procedures
1.2 Service Considerations
Listed below are some of the considerations that you should keep in mind during the disassembly
and assembly of the Compaq Aero 8000 H/PC Pro.
1.2.1 Tool and Software Requirements
To service the Aero 8000, you need the following:
„#Magnetic screwdriver
„#Torx T-8 screwdriver
„#Small Phillips or flat blade screwdriver
1.2.2 Screws
The screws used in the Compaq Aero 8000 H/PC Pro 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.
CAUTION: When servicing the computer, ensure that all screws are kept with the part with
which they belong. Using an improper screw during reassembly can damage the computer.
IMPORTANT: As each subassembly is removed from the computer, it should be placed away from the
work area to prevent damage.
1.2.3 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. Handle flex cables with extreme care; they can tear easily.
CAUTION: When servicing the computer, ensure that cables are placed in their proper
location during the reassembly process. Improper cable placement can damage the
computer.
1.2.4 Plastic Parts
Plastic parts can be damaged by the use of excessive force during disassembly and reassembly.
When handling the plastic parts, use care. Use a bezel removal tool to separate plastic components.
Apply pressure only at the points designated in the maintenance instructions.
