NOTE: To properly ventilate the computer, allow at least 7.6 cm (3.0 in) of clearance on the left side of

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.
