NOTE:
To properly ventilate the computer, allow at least 7.6 cm (3 in) of clearance on the left side

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.
