NOTICE: Positioning the microprocessor incorrectly can permanently damage the chip and the system when you turn on the system.
8. Install the microprocessor chip in the socket (see Figure 6-10).
a. If the release lever on the microprocessor socket is not all the way up, move it to that position now.
NOTICE: When placing the microprocessor chip in the socket, be sure that all of the pins on the chip go into the corresponding holes of the socket. Be
careful not to bend the pins.
b. With the pin-1 corners of the chip and socket aligned, set the chip 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, there is no need to use force (which could bend the pins if the chip is misaligned). When the
chip is positioned correctly, it should drop down into the socket with minimal pressure.
c. When the chip is fully seated in the socket, rotate the socket release lever back down until it snaps into place, securing the chip.

9. Place the new heat sink on top of the microprocessor chip (see Figure 6-11).
10. Replace the retention clip:
a. Orient the clip so that the release tab is facing the back of the system.
b. Hook the unfolded end of the clip over the tab on the edge of the socket facing the front of the system.
c. Press down on the release tab on the free end of the clip to snap the clip over the tab on the socket (see Figure 6-11).
