Attention

Do not open your computer or attempt any repair before reading and understanding the

“Important safety information” in the ThinkCentre Safety and Warranty Guide that came with

your computer. To obtain a copy of the ThinkCentre Safety and Warranty Guide, go to:

CAUTION:

The heat sink and microprocessor might be very hot. Turn off the computer and

wait three to five minutes to let the computer cool before opening the computer

cover.

Note:

When replacing the system board a new retention module for the

microprocessor heat sink is required. Make sure you have a new retention

module before beginning this procedure.

1. Remove the computer covers. See “Removing the computer cover” on page

86.

2. Lay the computer on its side for easier access to the system board.

3. Remove any adapter cards installed in the PCI connectors. See “Replacing a

PCI adapter card” on page 92.

4. Carefully take note of the location of all cable connections on the system

board and disconnect all cables. See “Identifying parts on the system board”

on page 85.

5. Remove the screws that secure the system board to the chassis.

6. Lift the system board out of the chassis.

7. Remove the memory modules from the failing system board and install them

in the same location on the new system board.

8. Lift the heat sink and fan assembly off the failing system board. Lay the heat

sink on its side so that the thermal grease does not come in contact with

anything.

9. 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 when you complete this procedure.

10. 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 on the new system board.

Important

To avoid damaging the microprocessor contacts, do not tilt the

microprocessor when installing it into the socket.

11. Lower the microprocessor straight down into the system board socket of the

new system board.
