Product Description
1.6 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 expansion board
■ Hard drive
■ Display
■ Keyboard and TouchPad
■ Audio
■ Intel Pentium 4 and Celeron processors
■ Fan
■ PC Card
■ Modem or modem/NIC
The notebook uses an electrical 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 notebook.
CAUTION: To properly ventilate the notebook, allow at least a
Ä
7.6-cm (3-inch) clearance around all sides of the notebook.
