Product Description
1.6 Design Overview
This section presents a design overview of key parts and features 
of the computer. 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/TouchPad or pointing stick
■Audio
■AMD Athlon and Duron processors
■Fan
■PC Card
■Modem or modem/NIC
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 left side of the computer.
Ä
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.
