✎
Steps 2 and 3 apply to computer models equipped with graphics subsystems with discrete memory. See steps 4

subsystems with UMA memory.
2. Loosen the four captive Phillips PM2.0×7.0 screws 1 that secure the fan/heat sink assembly to the
system board.
3. Remove the fan/heat sink assembly 2.
✎
Due to the adhesive quality of the thermal material located between the fan/heat sink assembly and system board
components, it may be necessary to move the fan/heat sink assembly from side to side to detach the assembly.
