CAUTION:
To prevent overheating, do not obstruct vents. Do not allow
a hard surface, such as a printer, or a soft surface, such as pillows or
thick rugs, to block airflow.
The tablet PC uses an electric fan for ventilation. The fan is
controlled by a temperature sensor and is designed to operate
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.
Cooling air is taken in through the air vent located on the rear of
the tablet PC. Exhaust air is expelled through the air vent located
on the left side of the tablet PC.
