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," to
identify replacement parts, and Chapter 5, "Removal and

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.
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.
