To remove the heat sink:  
 
 
CAUTION: To prevent the heat sink from tilting to one side during installation and removal 
procedures, use a diagonally opposite pattern (an “X” pattern) when loosening and tightening the 
four spring-loaded screws. Do not over tighten the heat sink’s spring-loaded screws to prevent them 
from breaking off. A maximum torque of 4 in-Ib is set for the system. 
1.  Loosen the four mounting pins. 
2.  Lift the heat sink away from the system board. 
 
 
CAUTION: Place heat sink down in an upright position with the thermal patch facing upward. Do 
not let the thermal patch touch the work surface.
