Product Description

1.5 Design Overview

This section presents a design overview of key parts and features of the notebook. Refer to to identify replacement parts, and Chapter 5, “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 processors
PC Card
CAUTION: To properly ventilate the notebook, allow at least a 7.6--cm
Ä
(3-inch) clearance on the left and right sides of the notebook.
Chapter 3, “Illustrated Parts Catalog,”
The notebook 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 notebook.
