Replacing the processor
WARNING: Before working inside your computer, read the safety 
information that shipped with your computer and follow the steps in Before 
working inside your computer. After working inside your computer, follow 
the instructions in After working inside your computer. For more safety best

CAUTION: If either the processor or the heat sink is replaced, use the 
thermal grease provided in the kit to ensure that thermal conductivity is 
achieved.
NOTE: A new processor ships with a thermal pad in the package. In some 
cases, the processor may ship with the thermal pad attached to it.
 
Procedure
1  Ensure that the release lever on the processor socket is fully extended in the 
open position.
CAUTION: The pin-1 corner of the processor has a triangle that aligns 
with the triangle on the pin-1 corner on the processor socket. When the 
processor is properly seated, all four corners are aligned at the same 
height. If one or more corners of the processor are higher than the 
others, the processor is not seated properly.
2  Align the notches on the processor with the tabs on the processor socket and 
place the processor in the processor socket.
CAUTION: Ensure that the processor-cover notch is positioned 
underneath the alignment post.
3  When the processor is fully seated in the socket, close the processor cover.
