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
. The first subsection explains which parts may be removed by the customer/owner, 
and the second subsection explains which parts should be serviced by the technician.
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.
Å
WARNING: Prior to servicing your Notebook, disconnect AC power cords and 
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.
