122 Hardware Maintenance Manual
13. Remove the microprocessor from the failing system board. See “Replacing the
microprocessor” on page 124.
14. The failing system board must be returned with a microprocessor socket cover
to protect the pins during shipping and handling. Install the microprocessor
socket cover removed from the new system board on the failing system board.
To install the microprocessor socket cover:
a. Make sure the microprocessor has been removed from the microprocessor
socket, and then close the microprocessor retainer and lock it into position
with the small handle.
b. Insert the tabs ▌1▐ of the socket cover into the hinged side of the socket,
and then press the other side of the socket cover downward until the tabs
▌2▐ snap into position.
15. On the new system board, release the lever securing the microprocessor
retainer and then pivot the retainer until it is fully open.
Note: There will be a black plastic cover on the microprocessor retainer to
protect the socket on the new system board. Remove the black plastic
cover and place it on the microprocessor socket of the failing system
board.
16. Holding the microprocessor with your fingers, position the microprocessor so
that the notches on the microprocessor are aligned with the tabs in the
microprocessor socket.
Important
To avoid damaging the microprocessor contacts, do not tilt the
microprocessor when installing it into the socket.
