CAUTION:
To properly ventilate the notebook, allow at least a 7.6-cm
(3-inch) clearance on all sides of the notebook.
The notebook uses an electric fan for ventilation. The fan is
controlled by a temperature sensor and is designed to come on
automatically when high temperature conditions exist. These
conditions can be caused by high external temperatures, heavy
system power consumption, certain power management/battery
conservation configurations, battery fast charging, and some
software applications. Exhaust air is displaced through the
ventilation grill located on the notebook rear panel.
