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

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.
