To properly ventilate the computer, allow at least a 7.6-cm (3-in) 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.
