Product Description

The notebook uses an electrical 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 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.

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.
