NOTE:
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.
