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 exposed to electrostatic discharge (ESD) may not seem to be
affected at all and works perfectly throughout a normal cycle. 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.
Typical Electrostatic Voltages
Relative Humidity
10% 40% 55%
Walking across carpet 35,000 V 15,000 V 7,500 V
Walking across vinyl floor 12,000 V 5,000 V 3,000 V
Motions of bench worker 6,000 V 800 V 400 V
Removing DIPS from plastic tubes 2,000 V 700 V 400 V
Removing DIPS from vinyl trays 11,500 V 4,000 V 2,000 V
Removing DIPS from styrofoam 14,500 V 5,000 V 3,500 V
Removing bubble pack from PCBs 26,000 V 20,000 V 7,000 V
Packing PCBs in foam-lined box 21,000 V 11,000 V 5,000 V
Note: 700 Volts can degrade a product.

Service Considerations
Listed below are some of the considerations to consider during the disassembly and
assembly of the Notebook.
Tool and Software Requirements
The following items are required to service the computer:
Compaq screwdriver kit (Spare Part No. 161946-001)
Torx T-9 screwdriver
3/16-in. and 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, and 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.

Cables and Connectors
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. Most cables used throughout the
unit are ribbon cables.
Cables
Use the following precautions when handling cables to avoid damage to the cable or
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 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.
Ä
CAUTION: When servicing these computers, ensure that cables are placed in their
proper location during the reassembly process. Improper cable placement can
cause severe damage to the unit.
The following illustrations show the proper placement for each cable:
Connectors and Plastic Parts
Plastic parts can be damaged by the use of excessive force during disassembly and
reassembly. When handling these plastic parts, use care. Apply pressure only at the points
designated in the maintenance instructions.

ZIF Connector
The 1200XL Series Notebooks use zero insertion force (ZIF) connectors on the system
board.
Ä
CAUTION: A ZIF connector and its attached cable can be easily damaged. Handle
only the connector slide when removing or replacing a cable. Never pull or twist on
the cable while it is connected.
To remove a cable from a ZIF connector, lift both corners of the ZIF connector and slide the
cable out simultaneously with constant light force.
Ä
CAUTION: When servicing this notebook, ensure that cables are placed in their
proper location during the reassembly process. Improper cable placement can
damage the notebook.
