Turn the ZIF retaining screw to release the CPU chip. When properly released you will be able to easily lift the CPU out of its socket.

Insert the new CPU into this socket. Note carefully that you must line up the corner of the chip with the two missing pins and the corner of the socket with the two missing pin holes.

Apply heat sink compound to the raised portion of new CPU chip. Also apply heat sink compound to the smaller chip in the upper right corner of the photo.
