1.2 Resetting the Computer

If the computer you are servicing has an unknown password, follow the steps below to reset the password. These steps also clear CMOS.

The following steps will not clear an unknown password if the stringent security option has been enabled in the BIOS. If stringent security is enabled, the system board must be replaced to reset an unknown password. Refer to Section 5.13, “RTC Battery,” for more information on replacing the system board.

Before replacing the system board, perform the steps below to be sure that stringent security has been properly enabled.

Enabling stringent security provides enhanced protection for the power-on password and administrator password and other forms of power-on authorization. Stringent security is enabled/disabled by accessing the Password Options menu in the Computer Setup utility. Refer to Section 2.1, “Computer Setup,” for more information.

1.Prepare the computer for disassembly (refer to Section 5.3, “Preparing the Computer for Disassembly,” for more information). Remove the real-time clock (RTC) battery (refer to Section 5.13, “RTC Battery,” for more information on removing and replacing the RTC battery).

2.Wait approximately 5 minutes.

3.Replace the RTC battery and reassemble the computer.

4.Connect AC power to the computer. Do not reinsert any batteries at this time.

5.Turn on the computer.

All passwords and all CMOS settings have been cleared.

Product Description

1.5 Design Overview

This section presents a design overview of key parts and features of the computer. Refer to Chapter 3, “Illustrated Parts Catalog,” to identify replacement parts, and Chapter 5, “Removal and Replacement Procedures,” for disassembly steps.

The system board provides the following device connections:

■AMD Turion 64 or Mobile AMD Sempron processors

■Audio

■Display

■ExpressCard

■Fingerprint reader board (HP Compaq nx6325 models only)

■Hard drive

■Keyboard and TouchPad

■Memory module

■Mini Card module

■PC Card

ÄCAUTION: To properly ventilate the computer, allow at least a 7.6-cm (3-inch) clearance on the left and right sides of the computer.

The computer uses an electric fan for ventilation. The fan is controlled by a temperature sensor and is designed to turn on automatically when high temperature conditions exist. These conditions are affected by high external temperatures, system power consumption, power management/battery conservation configurations, battery fast charging, and software. Exhaust air is displaced through the ventilation grill located on the left side of the computer.

Troubleshooting

ÅWARNING: Only authorized technicians trained by HP 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, do not attempt to make repairs at the component level or 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.
