Fan/heat sink assembly

NOTE: The fan/heat sink assembly spare part kit includes replacement thermal material. Replacement thermal material is also available in the Thermal Material Kit, spare part numbers 650277-001 (for use only with computer models equipped with an AMD processor) and 646135-001 (for use only with computer models equipped with an Intel processor).

NOTE: To properly ventilate the computer, allow at least 7.6 cm (3 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.

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.
