Product Description

1.5 Design Overview

This section presents a design overview of key parts and features of the computer. Refer to Chapter 3, “Illustratdocking deviceed

Parts Catalog,” to identify replacement parts, and Chapter 5, “Removal and Replacement Procedures,” for disassembly steps.

The system board provides the following device connections:

■ Intel Pentium M processors

■ Audio

■ Digital media card

■ Display

■ ExpressCard

■ Hard drive

■ Keyboard

■ Memory module

■ Mini Card devices

■ PC Card

■ To uc hP ad

CAUTION: 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 applications. Exhaust air is displaced through the ventilation grill located on the left side of the computer.

1–20 Maintenance and Service Guide

Troubleshooting

WARNING: 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.

2.1 Computer Setup

Computer Setup is a preinstalled, ROM-based utility that can be used even when the operating system is not working or will not load. If the operating system is working, the computer restarts the operating system after you exit Computer Setup.

Pointing devices are not supported in Computer Setup; you
