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 indication of component replacement or printed wiring board modifications
may void any warranty or exchange allowances.
CAUTION:
To properly ventilate your system, you must provide at least 3 inches
(7.62 cm) of clearance on the front and back of the computer.
