NOTE:
To properly ventilate the computer, allow at least
7.6 cm
(3.0 in) of 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.
Before removing the fan/heat sink assembly, follow these steps:
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.
2.
Disconnect all external devices connected to the computer.
3.
Disconnect the power from the computer by first unplugging the power cord from the AC outlet and
then unplugging the AC adapter from the computer.

).
5.
