Technician Notes
!
WARNING: Only authorized technicians trained by Compaq should attempt to 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
indications of component replacement or printed wiring board modifications may void any
warranty.
!
WARNING: To reduce the risk of electric shock or damage to the equipment:
•
Do not disable the power grounding plug. The grounding plug is an important safety feature.
•
Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all
times.
Disconnect the power from the computer by unplugging the power cord either from the electrical
outlet or the computer.
CAUTION: The computer is designed to be electrically grounded. To ensure proper operation, plug
the AC power cord into a properly grounded AC outlet only.
