Product Description
1.4 Design Overview
This section presents a design overview of key parts and features 
of the computer. Refer to Chapter 3, “Illustrated Parts Catalog” 
and Chapter 5, “Removal and Replacement Procedures.”
The system board provides the following device connections:

Memory expansion board

Hard drive

Display

Keyboard/TouchPad

Audio

Intel Pentium III or Intel Celeron Processors

Fan

PC Card

Modem or modem/NIC

Microphone
The computer 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 right side of the computer.
ÄCAUTION: To properly ventilate the computer, allow at least a 3-inch 
(7.6 cm) clearance on the left and right sides of the computer.
