Ê Loosen the four captive screws (combihexagon) on the heat sink in the
following pattern: (4)->(3)->(2)->(1).
Ê Carefully turn the heat sink back and forth to detach it from the processor.
I This may be necessary due to the adhesive quality of the thermal
paste located between the heat sink and processor.
