CAUTION: To properly ventilate the notebook, allow at least a 7.6-cm 
(3-inch) clearance on the left and right sides of the notebook.
The notebook uses an electric fan for ventilation. The fan is 
controlled by a temperature sensor and is designed to turn 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 left side of the notebook.
