1.4 Design Overview
This section presents a design overview of key parts and features of the computer. For
assembly/disassembly instructions for the parts described in this section, refer to
Chapter 5.
System Board
The system board provides the following device connections:
■ Memory expansion board
■ MultiBay device
■ Hard drive
■ Display
■ Keyboard/EasyPoint IV pointing device or touchpad
■ Audio
■ Pentium II processor
■ Fan
■ PC Cards
■ Modem
The computer is equipped with an Intel Mobile Pentium III 500-MHz or Intel Mobile
Pentium II 400-MHz processor. For ventilation, an electrical fan is installed. The fan
operates on from 5 to 12 volts and 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 left 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.
