6. Install the microprocessor in the socket. See Figure6-9.

a. If the release lever on the microprocessor socket is not all the way up, move it to that position now. See Figure6-9.



b. With the pin-1 corners of the processor and socket aligned, set the processor lightly in the socket and make sure that all pins are matched with

the correct holes in the socket.

Because the system uses a ZIF microprocessor socket, you do not need to use force (which could bend the pins if the microprocessor is

misaligned). When the microprocessor is positioned correctly, it should drop down into the socket with minimal pressure.

c. When the processor is fully seated in the socket, rotate the socket release lever back down until it snaps into place, securing the processor.

7. Place the new heat sink on top of the microprocessor. See Figure6-10.

8. Replace the two retention clips:

a. Orient the retention clips. The clips are designed in pairs so that each clip fits only one end of the socket; when installed, the clips face opposite

ways.

l For processor 1, the outer retention clip's release tab faces the back of the system; the inner retention clip faces the opposite way.

l For processor 2, the outer retention clip's release tab faces the front of the system; the inner retention clip faces the opposite way.

b. Hook the end of the clip that is opposite the release tab over the retaining tab on the edge of the socket.

c. Press the clip down so that the hole in the middle of the clip engages the tab in the side of the socket.

d. Continue pressing down on the release tab while pressing in on the free end of the clip until the end of the clip snaps over the tab on the corner

of the socket. See Figure6-10.

NOTICE: When placing the microprocessor in the socket, be sure that all of the pins on the processor go into the corresponding holes of the socket. Be

careful not to bend the pins.
