Lenovo J SERIES 3000 - Manual (Page 113)

Notes:
a. Your microprocessor and socket might look different than the one illustrated.
b. Note the orientation of the microprocessor in the socket. Look for the small triangle on one corner of
the microprocessor. This is important when reinstalling the microprocessor on the new system board.
c. Do not drop anything onto the microprocessor socket while it is exposed. The socket pins must be
kept as clean as possible.
16. Holding the microprocessor with your fingers, position the microprocessor so that the small triangle 1 on
one corner is aligned with the corresponding triangle on the socket.
17. Make sure that the small handle is in the raised position.
18. Lower the microprocessor straight down into the system board socket of the new system board.
19. Lower and latch the handle to secure the microprocessor in the socket.
20. Install the retention module that was removed from the rear of the failing system board on the new
system board.
21. Install the heat sink and fan assembly on the new system board.
