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, no
one should attempt to make repairs at the component level or to make modifications to
any printed wiring board. Improper repairs can create a safety hazard. Any indication of
component replacement or printed wiring board modifications may void any warranty or
exchange allowances.
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.
