Product Description

1.5 Design Overview

This section presents a design overview of key parts and features of the computer. Refer to to identify replacement parts, and Chapter 6, “Removal and

Replacement Procedures,” for disassembly steps.

The system board provides the following device connections:

■ Memory module

■ Mini PCI communications devices

■ Hard drive

■ Display

■ Keyboard and TouchPad

■ Audio

■ Intel Pentium M and Intel Celeron M processors

■ PC Card

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.

Chapter 4, “Illustrated Parts Catalog,”

The computer uses an electric fan for ventilation. The fan is controlled by a temperature sensor and is designed to be turned 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.

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.
