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 requirements.
Exhaust air is displaced through the ventilation grill located on the left side of the computer.
