NOTE: 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 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.
