Technician Notes
WARNING: Only authorized technicians trained by Compaq should repair this equipment. All
troubleshooting and repair procedures are detailed to allow only subassembly/module level repair.
Because of the complexity of the individual boards and subassemblies, the user should not attempt to
make repairs at the component level or to make modifications to any printed circuit board. Improper
repairs can create a safety hazard. Any indications of component replacement or printed circuit board
modifications may void any warranty.
Serial Number
When requesting information or ordering spare parts, the computer serial number should be provided to Compaq. The
serial number can be found on the rear of the computer next to the fan grill and on the front bezel behind the drive
access door.

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 be
affected at all and will work perfectly throughout a normal cycle. Or it may function
normally for a while, then degrade 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.

activities.
