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.
