Remove the heat sink:
1. Loosen the four Phillips PM2.0×10.0 captive screws 1 that secure the heat sink to the system board.
2. Remove the heat sink 2 by lifting it straight up.
✎
The thermal material must be thoroughly cleaned from the surfaces of the heat sink 1 and 2, the processor 3,
and graphics subsystem component 4 on the system board each time the heat sink is removed. Thermal material
is included with all system board, heat sink, and processor spare part kits.
Reverse this procedure to install the heat sink.
