Removal Sequence
This section describes the removal and replacement process for the Presario 1400 Series Notebook.
The procedures are divided into two subsections: The Customer Removable Parts and The Service
Removable Parts
and the second subsection explains which parts should be serviced by the technician.
. The first subsection explains which parts may be removed by the customer/owner,
The Customer Removable Parts
Serial Number
Report your Notebook’s serial number 1 to Compaq when requesting information or ordering spare
parts. The serial number is located on the underside of the Notebook as shown below.
WARNING: Prior to servicing your Notebook, disconnect AC power cords and
Å
external devices, and remove the battery pack and any PC Cards. Failure to
disconnect electrical devices may cause damage to the Notebook and loss of
human life.

Electrostatic Discharge
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 that has been exposed to electrostatic discharge (ESD) may not seem to be affected and
work perfectly throughout a normal cycle. Although the Notebook may function normally for a period
of time, it may have been degraded in the internal layers, reducing the 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 level of
electrostatic voltage.

Service Considerations
During the disassembly and assembly of your Notebook, please keep in mind the considerations
listed below.
Tool and Software Requirements
Customer serviceable parts only require the following items during disassembly:
•
Small standard screwdriver
•
Small Phillips screwdriver
•
Diagnostics software
Screws
The screws used on the customer removable parts are Phillips. These screws are not
interchangeable. If an incorrect screw is applied during the reassembly process, it can damage the
unit. Compaq strongly recommends that you keep all screws with their respective parts as they are
removed during disassembly. Then replace the screws in their proper locations.
Important: As each subassembly is removed from the Notebook, place it away from the
work area to prevent damage.
Note: Screws inside the Compaq Presario 1400 Series Portable Notebooks vary in size
and are not interchangeable. During reassembly care must be taken to return the
correct screws to their original location. Keep all screws with their respective
subassembly during removal.

Service Considerations
During the disassembly and assembly of the Notebook, please keep in mind the considerations listed
below.
Tool and Software Requirements
To service the Notebook, the following items are required:
•
Torx T-8 or T-9 screwdriver
•
5mm nut drivers (for screwlocks and standoffs)
•
Small standard screwdriver
•
Small Phillips screwdriver
•
Diagnostics software
Screws
The screws are not interchangeable. If an incorrect screw is applied during the reassembly process,
it can damage the unit. Compaq strongly recommends that you keep all screws with their respective
parts as they are removed during disassembly. Then replace the screws in their proper locations.
As each subassembly is removed from the Notebook, place it away from the work area to prevent
damage.

Cables and Connectors
Most of the cables inside the Notebook are ribbon cables. Handle cables with extreme care to avoid
damage. During insertion or removal from the connector, apply only the amount of pressure
required to seat or unseat the cable, handling it by the connector whenever possible. In all cases,
avoid bending, twisting, or tearing the cables. Route cables in such a way that they cannot be
caught or snagged by parts being removed or replaced.
Cables
To avoid damage to the cable or the Notebook, the following precautions should be taken when
handling cables:
•
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 in such a manner that they cannot be caught or snagged by parts being
removed or replaced.
•
Handle flex cables with extreme care; they can tear easily.
