Removal Sequence
This chapter provides details for removing and replacing each component of the Presario
1200XL units.
Electrostatic Discharge
When removing or replacing parts, be careful to discharge static electricity before touching
the internal Notebook components. A sudden discharge of static electricity from a finger or
other conductor can destroy static-sensitive devices and microcircuitry. Often the spark is
neither felt nor heard, but damage occurs. An electronic device exposed to an electrostatic
discharge may not seem to be affected and continue to work perfectly throughout a normal
cycle. However, the discharge degrades internal layers, which reduces the operating life of
the device. 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.
The table below shows the amount of static electricity generated by common activities
associated with servicing computers.

Tool and Software Requirements
The following items are required to service the Notebook:
• Torx T-9 screwdriver
• 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.
Connectors and Plastic Parts
Plastic parts can be damaged by the use of excessive force during disassembly and
reassembly. When handling plastic parts, use care. Apply pressure only at the points
designated in the instructions. Most of the connectors in these Notebooks are

Cables
Most cables used throughout the unit are ribbon cables.
Cables must be handled with extreme care to avoid damage. Use the following precautions
when handling cables to avoid damage to the cable and the Notebook:
• Always handle cables by their connectors.
• In all cases avoid bending, twisting, pulling, or tearing cables.
• Apply only the minimum pressure required to seat or unseat cables from their
connectors.
• Place the cables so that they are not caught or snagged by parts being removed or
