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 be turned 
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 applications. 
Exhaust air is displaced through the ventilation grill located on 
the left side of the notebook.
