NOTE: 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.
