Compaq Deskpro 1000 Series of Personal Computers 4-5
4.2.2 Screws
The screws used in the computer are not interchangeable. They may have standard or metric
threads and may be of different lengths. 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.
✎
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
Most cables used throughout the unit are flat, flexible cables. These 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:
When servicing this computer, ensure that cables are placed in their proper location during the
reassembly process. Improper cable placement can damage the computer.
4.2.4 Hard Drives
Handle hard drives as delicate precision components, avoiding all physical shock and vibration.
This applies to failed drives as well as spares.
Use only the packaging provided by Compaq for shipping.
Do not remove hard drives from the shipping package for storage.
Keep hard drives in their protective packaging until they are actually mounted in the CPU
or external storage unit.
Avoid dropping drives from any height onto any surface.
4.2.5 Plastic Parts
Plastic parts can be damaged by the use of excessive force during disassembly and reassembly.
When handling the plastic parts, use care. Do not use a screwdriver or similar tool to pry apart the
plastic components.
4.2.6 Lithium Battery
The battery that came with the computer is replaceable.
CAUTION:
Never attempt to remove a lithium battery. You can damage the system board in such an
attempt, thereby making it unusable. Do not abuse or disassemble the lithium battery, as it may explode if
mistreated.
