1.3 Design Overview

This section presents a design overview of key parts and features of the computer. Refer
to Chapter 3 for the illustrated parts catalog and Chapter 5 for removal and replacement
procedures.

System Board

The system board provides the following device connections:
Memory expansion board
Hard drive
Display
Keyboard/Touchpad pointing device
Audio
Pentium II/Celeron processor
Fan
PC Cards
Modem
The computer is equipped with an Intel Pentium III 500-MHz, Intel Pentium II
333-MHz, or Celeron 450- or 333-MHz processor. For ventilation, an electrical fan is
installed. The fan is controlled by a temperature sensor. The fan 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 right side of the computer.
CAUTION: To properly ventilate the computer, allow at least a 3-inch (7.6 cm) clearance
on the left and right sides of the computer.
