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:
■ Intel Core Duo and Celeron processors
■ Audio
■ Display
■ Hard drive
■ Keyboard
■ Memory module
■ Mini Card devices
■ To uc hP ad
Ä
CAUTION: To properly ventilate the computer, allow at least a 7.6-cm
(3-inch) clearance on the left and right sides and rear panel 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 computer
rear panel.

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.
