CAUTION: To properly ventilate the computer, allow at least a 7.6-cm
(3-inch) clearance on the left and right sides of the computer.
The computer uses an electric fan for ventilation. The fan is
controlled by a temperature sensor and is designed to be turned
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.
