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.
