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 modification may
void any warranty or exchange allowances.
Utilities that are preinstalled on the computer include:
PhoenixBIOS Setup Utility—Allows you to modify or
■
restore factory default settings and configure the system
BIOS to diagnose and solve minor problems.

Using the PhoenixBIOS Setup Utility
The PhoenixBIOS Setup Utility (PSU) is built into the system.
You can configure the system BIOS and modify or restore factory
default settings, such as date and time, types of disk drives, power
management, and password settings. To run PSU, press the
key during system startup. When the main screen displays, use

Power Cord Set Requirements
3-Conductor Power Cord Set
The computer’s wide range input feature permits it to operate
from any line voltage from 100 to 120 or 220 to 240 volts AC.
The power cord set received with the computer meets the
requirements for use in the country where the equipment is
purchased.
Power cord sets for use in other countries must meet the
requirements of the country where the computer is used. For more
information on power cord set requirements, contact a Compaq
authorized reseller or service provider.
General Requirements
The requirements listed below are applicable to all countries:
The length of the power cord set must be at least 5.00 feet
■
(1.5 m) and a maximum of 6.50 feet (2.0 m).
B
All power cord sets must be approved by an acceptable
■
accredited agency responsible for evaluation in the country
where the power cord set will be used.
The power cord set must have a minimum current capacity of
■
10A and a nominal voltage rating of 125 or 250 volts AC, as
required by each country’s power system.
The appliance coupler must meet the mechanical
■
configuration of an EN 60 320/IEC 320 Standard Sheet C13
connector, for mating with appliance inlet on the back of the
computer.
