Removal and replacement procedures
Remove the fan/heat sink assembly:
✎
Due to the adhesive quality of the thermal material located between the fan/heat sink assembly and system board
components, you might need to move the fan/heat sink assembly from side to side to detach the assembly.
Ä
CAUTION: To avoid damage to the processor, loosen the fan/heat sink assembly screws in the sequence indicated on the heat
sink assembly. Likewise, tighten the screws in the same sequence when installing the fan/heat sink assembly.
✎
Steps 1 through 4 apply only to computer models equipped with graphics subsystems having UMA memory.
