Fan/heat sink assembly
NOTE:
The fan/heat sink assembly spare part kit includes replacement thermal material.
Description
For use only on computer models equipped with an AMD processor
For use only on 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.
Before removing the fan/heat sink assembly, follow these steps:
1.
