processor onto the processor extender board. Figure 4-17 shows the correct placement of the

CAUTION Test the alignment of the assembly to the socket by gently moving the assembly back
and forth with the palm of your hand—you should feel little or no sideplay. However,
because the assembly is not yet tightened, it may tilt slightly towards the center of
the extender board—this is acceptable.
CAUTION Before locking the processor assembly into its socket, ensure that the power cable is
not pinched between the heatsink and sheet metal frame of the extender board. See
Figure 4-17 for the correct placement of the processor power cable.
Step 9. Insert the 2 mm hex end of the processor installation tool through the processor into the ZIF socket
lock. Rotate the socket 180 degrees clockwise to lock the processor to the processor extender board.
