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

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.
