5. Install the microprocessor chip in the socket (as shown in the preceding figure) by performing the following steps.
NOTICE: You must position the microprocessor chip correctly in the socket to avoid permanent damage to the chip and the
computer when you turn on the system.
a. If the release lever on the microprocessor socket is not all the way out, move it to that position now.
b. With the pin-1 corners of the chip and socket aligned, align the pins on the chip with the holes in the socket.
c. Set the chip lightly in the socket and make sure that all pins are headed into the correct holes. Because your system uses a ZIF
microprocessor socket, you do not need to use force, which could bend the pins if the chip is misaligned. When the chip is
positioned correctly, press it with minimal pressure to seat the microprocessor in the socket. Be careful not to bend the pins.
d. When the chip is fully seated in the socket, pivot the microprocessor-socket release lever back toward the socket until it snaps
into place, securing the chip.
