To properly ventilate the computer, allow at least 7.6 cm (3 in) of clearance on the left side 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 requirements. Exhaust air is displaced through the ventilation grill located on the left side
of the computer.
