Remove the heat sink:
1. Turn the system board upside down with the front toward you.
✎
Steps 2 and 3 apply to computer models equipped with graphics subsystems with discrete memory. See steps 4
and 5 for instructions on removing the heat sink on computer models equipped with graphics subsystems with
UMA memory.
2. Loosen the four Phillips PM2.5×9.0 captive screws 1 and the two Phillips PM2.0×5.0 captive screws 2 that
secure the heat sink to the system board.
3. Remove the heat sink 3.
✎
Due to the adhesive quality of the thermal material located between the heat sink and system board components,
it may be necessary to move the heat sink from side to side to detach the heat sink.
