Notes
a. Note the orientation of the notches on the microprocessor. This
is important when reinstalling the microprocessor on the new
system board.
b. Do not drop anything onto the microprocessor socket while it is
exposed. The socket pins must be kept as clean as possible.
16. 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.
17. 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.
18. Lower the microprocessor straight down into the system board socket
of the new system board.
19. To secure the microprocessor in the socket, close the microprocessor
retainer and lock it into position with the small handle.
20. Install the retention module for the heat sink and fan assembly on the
system board.
