Procedure
 
1.
When opening the bottom housing, rotate the base so the optical drive door is on the 
right. (This position is less stressful on the internal cables when the bottom is open).
2.
Remove the four torx screws.
 
Replacement Note:
 
 
 
 
 
These torx screws must be tightened to at least 17 in.-lbs. If you do 
not have a torque driver, you will have to make sure these screws are tightened by hand 
FIRMLY, BUT NOT FORCIBLY. Or, purchase the service tool (076-0899) in order to ensure 
the thermal pipe is firmly mated with the top base. If the bottom housing is not securely 
attached to the base in this fashion, the CPU may overheat and become damaged. For 
more information, refer to “Thermal Paste Application’” in this chapter. Rotate the base so 
that the optical drive door is on the right.
