Turn the system board upside down, with the front toward you. NOTE: Steps 2 through 4 apply to computer models equipped with switchable discrete graphics. See steps 5 through 7 for heat sink assembly removal information for computer models equipped with UMA graphics. 2. Remove the four Phillips M2.5x4.0 screws (1) and the three Phillips PM2.5x4.0 screws (2) that secure the heat sink assembly to the system board. 3. Remove the heat sink assembly (3) from the system board.
