NOTE:
To properly ventilate the computer, allow at least a 7.6-cm (3-inch) clearance on the left side
of the computer. The computer 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 are affected by high external temperatures, system power consumption, power
management/battery conservation configurations, battery fast charging, and software requirements.
Exhaust air is displaced through the ventilation grill located on the left side of the computer.

1.
Shut down the computer. If you are unsure whether the computer is off or in Hibernation, turn the
computer on, and then shut it down through the operating system.
