To remove and replace the CPU
1
Unlock the CPU socket lever and raise it into the open position (flex the lever away from the retention post, and
then raise it).
2
Open the load plate.
3
Grasp the CPU by its edges, lift it out of the socket, and then place the CPU in a safe place.
Note:
If you remove the CPU from the motherboard to install it on a new motherboard, unpack the new
motherboard and remove the protective plastic cover from the CPU socket. Transfer the protective cover to the
CPU socket of the old motherboard to protect the circuitry.
4
Wipe the contact surface of the CPU (the smooth, gray side of the chip) with a clean, lint-free cloth to ensure
proper contact with the new heatsink.
If you remove the CPU from the motherboard to install it on a new motherboard, make sure that you completely
remove any thermal compound residue on the surface of the CPU and at the base of the heatsink. It may help to
scrape all the residue off of the surface using the flat edge of something non-conductive.
Be aware that both the cooling assembly and the CPU may be very hot. You may need to allow the
components to cool before you attempt to remove them.
