Removal and Replacement
This chapter details removing and replacing each component of the Presario 1800XL
Notebook Computers.
Electrostatic Discharge
When removing or replacing parts, be careful to discharge static electricity before touching
the Notebook’s internal 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 affected and 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.
Generated Electrostatic Voltage
Activity
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
CAUTION: As little as 700 Volts can degrade Notebook components. Be sure to
ground yourself before touching the Notebook or its subassemblies.

Tool and Software Requirements
The following items are required to service the Notebook:
• Torx T-8 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.f
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.

ZIF Connector
The 1800XL Series Notebooks use zero insertion force (ZIF) connectors on the system
board.
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
Ä
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.
CAUTION: When servicing this Notebook, ensure that cables are placed in their
proper location during the reassembly process. Improper cable placement can
Ä
damage the Notebook.

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 Notebook:
• Always handle cables by their connectors.
• In all cases, avoid bending, twisting, pulling, or tearing cables.
• Apply only the minimum force required to seat or unseat cables from their
connectors.
• Ensure that cables are routed 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.
CAUTION: When servicing these Notebooks, ensure that cables are placed in their
proper location during the reassembly process. Improper cable placement can
Ä
cause severe damage to the unit.
