NOTE: To properly ventilate the computer, allow at least a 7.6-cm (3-inch) clearance on the right
side and rear panel 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.
