Product Description
1.5 Design Overview
This section presents a design overview of key parts and features
of the notebook. 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:
■ Memory module
■ Mini PCI communications devices
■ Hard drive
■ Display
■ Keyboard and TouchPad
■ Audio
■ Intel Pentium 4 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.
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.

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.
