7. Align the pin-1 corner of the microprocessor with the pin-1 corner of the microprocessor socket, which is also identified by a small triangle. See Figure 4 -
12 .
Figure 4-12. Installing the Microprocessor
8. Install the microprocessor in the socket. See Figure 4 -12 .
a. If the release lever on the microprocessor socket is not all the way up, move it to that position now. See Figure 4 -12 .
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.
9. Peel away and discard the thin plastic cover that protects the thermal grease on the new heat sink.
10. Place the heat sink on top of the microprocessor, grease side down. See Figure 4 -13 .
11. Replace the two retention clips:
a. Orient the retention clips. When installed, the clips face opposite directions:
l For processor 1, the outer retention clip's release tab faces the back of the system; the inner retention clip faces the opposite direction.
l For processor 2, the outer retention clip's release tab faces the front of the system; the inner retention clip faces the opposite direction.
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 (you may need to also press 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 4 -13 .

NOTICE: Positioning the microprocessor incorrectly can permanently damage the processor and the system when you turn on the system.
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.
NOTE: To ensure that the proper amount of thermal interface grease is present, use the new heat sink included in the microprocessor upgrade
kit.
