Reassembly Notes 
 
Caution 
Each time you install a new CPU module, you must also replace the heat sink’s thermal pad to 
maintain optimum heat transfer. Use a sharp knife or scraper to carefully remove the old thermal 
pad from the heat sink, then attach the new thermal pad. 
 
•  The CPU module is keyed for installation, and can be inserted only one way. 
•  Carefully insert the CPU module into the motherboard, and swing the locking arm forward and 
down. Make sure the clip on the right side of the CPU module socket secures the locking arm. 
•  Be sure to replace the thermal pad on the heat sink, as described in the reassembly notes on  
page 2-47.
