This section explains the removal and replacement procedures for the 1700XL unit.
Serial Number Location
Report the unit’s serial number to Compaq when requesting information or ordering
spare parts. The serial number is located underneath the Notebook as shown below.
A sudden discharge of static electricity from a finger or other conductor can destroy
static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but
damage occurs. An electronic device exposed to electrostatic discharge (ESD) may work
perfectly throughout a normal cycle and may not seem to be affected at all. However,
although it may function normally for a while, it may be degraded in the internal layers,
reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases,
the discharge contains enough power to alter device parameters or melt silicon junctions.
Generating Static
The table below shows activities that generate static electricity and the associated
electrostatic voltage level.

Listed below are some of the considerations to consider during the assembly and
disassembly of the Notebook.
Tool and Software Requirements
The following items are required to service the computer:
•5mm nut drivers (for screwlocks and standoffs)
•Small standard screwdriver
•Small Phillips screwdriver
•Diagnostics software
Screws
The screws used in the Notebook 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 Notebook, place it away from the
work area to prevent damage.
Most cables used throughout the unit are ribbon cables. 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.
Cables
Use the following precautions when handling cables to avoid damage to the cable or the
Notebook:
•Always handle cables by their connectors.
•Avoid bending, twisting, or pulling on the cables.
•Apply minimum required force when seating or unseating the cables from their
connectors.
•Place the cables carefully so that they cannot be caught or snagged by parts being
removed or replaced.
•Handle flex cables with extreme care; they can tear easily.

proper location during the reassembly process. Improper cable placement can
cause severe damage to the unit.
When servicing these computers, ensure that cables are placed in their

Connectors and Plastic Parts
Plastic parts can be damaged by the use of excessive force during disassembly and
reassembly. When handling the plastic parts, use care. Apply pressure only at the points
designated in the maintenance instructions.
Before beginning Removal & Replacement Procedures, complete the following steps:
1. Disconnect AC power and any external devices.
2. Remove the QuikDock (pg 8

Note: The Compaq Presario 1700 Series Portable Computers have several screws of
various sizes that are not interchangeable. During disassembly, place screws in
their correct location. During removal keep screws with their respective
subassembly to make reassembly easy.
