Compaq Technician Notes

WARNING: To reduce the risk of personal injury from electrical shock and
hazardous energy levels, do not exceed the level of repair specified in these
procedures. Because of the complexity of the individual boards and
subassemblies, do not attempt to make repairs at the component level or make
modifications to any printed wiring board. Improper repairs could create conditions
that are hazardous.

WARNING: To reduce the risk of electric shock or damage to the equipment:

Disconnect power from the computer by unplugging the power cord from either
the electrical outlet or the computer.

Do not disable the power cord grounding plug. The grounding plug is an important
safety feature.

Plug the AC adapter or power cord into a grounded (earthed) electrical outlet that
is easily accessible at all times.

CAUTION: To properly ventilate the system, you must provide at least 6 inches
(15 cm) of clearance at the front of the workstation and 3 inches (7.6 cm) at the
back.

IMPORTANT: Any indication of repair at the component level or modification of a printed
wiring board may void any warranty.
