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.
WARNING: The computer is designed to be
electrically grounded. To ensure proper operation,
plug the AC power cord into a properly grounded
electrical outlet only.
CAUTION: To properly ventilate the system, you
must provide at least 3 inches (7.62 cm) of clearance
on the left and right sides of the computer.
Serial Number
When requesting information or ordering spare parts, the computer serial number
should be provided to Compaq. The serial number is located on the bottom of the
computer.
