Replacing the Processor
Note: You will need to apply new thermal grease to the top of the replacement processor before 
installing it on the logic board. Steps 1 and 2 below explain how to apply the thermal grease.Using the syringe of thermal grease that came with the replacement processor, apply the 
1.  
entire contents of the syringe (approximately 4.5 cc) to the top surface of the processor.  
Important: Be sure not to get grease anywhere on the processor other than the very top, flat 
surface that directly contacts the heat sink.  
Use the edge of the package that the alcohol wipe came in as a spatula to spread the

thermal grease evenly over the entire top surface of the processor. Scrape off any excess 
grease with the package edge, then discard the package.
