Description
Fan/heat sink assembly
NOTE:
To properly ventilate the computer, allow at least a 7.6-cm (3-inch) clearance on the right
side and rear panel 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.

computer on, and then shut it down through the operating system.
