of the ThinkCentre Safety and Warranty Guide, go to: http://www.lenovo.com/support 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. This section provides instructions on how to remove and replace the system board. The procedure varies depending upon the machine type. 1. Remove the cover. See "Removing the computer cover" on page 69. 2. Place the computer on its right side to help make the system board more accessible. 3. Remove any adapter cards installed in the PCI connectors. 4. Disconnect the signal and power cables from the hard disk drive and remove the hard disk drive out of the chassis. See "Replacing the primary hard disk drive" on page 82. 5. Disconnect the heat sink and fan assembly cable from the system board. And lift the heat sink and fan assembly off the failing system board. See the system board illustration for your machine type at "System board connectors" on page 68. 6. Carefully take note of the location of all cable connections on the system board and disconnect all cables. See the system board illustration for your machine type at "System board connectors" on page 68. 7. Remove the screws that secure the system board to the chassis. 8. Remove the failing system board out of the chassis. 9. 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. Release the lever securing the microprocessor retainer and open the retainer to access the microprocessor. b. Grasp the microprocessor on the sides and lift it straight up and out of the socket. Do not touch the contacts on the microprocessor socket. c. Align the notches 1 of the microprocessor socket cover with the alignment keys 2 of the microprocessor socket. Lower the socket cover straight down into the microprocessor socket on the system board. Note: Your microprocessor socket and cover might look slightly different from the illustration. d. Carefully press the socket cover straight downwards until it is secured into the socket. Chapter 8.

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.

This section provides instructions on how to remove and replace the system board. The procedure varies

depending upon the machine type.

1. Remove the cover. See “Removing the computer cover” on page 69.

2. Place the computer on its right side to help make the system board more accessible.

3. Remove any adapter cards installed in the PCI connectors.

4. Disconnect the signal and power cables from the hard disk drive and remove the hard disk drive out of

the chassis. See “Replacing the primary hard disk drive” on page 82.

5. Disconnect the heat sink and fan assembly cable from the system board. And lift the heat sink and

fan assembly off the failing system board. See the system board illustration for your machine type at

“System board connectors” on page 68.

6. Carefully take note of the location of all cable connections on the system board and disconnect

all cables. See the system board illustration for your machine type at “System board connectors”

on page 68.

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

8. Remove the failing system board out of the chassis.

9. 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:

Release the lever securing the microprocessor retainer and open the retainer to access the

microprocessor.

b. Grasp the microprocessor on the sides and lift it straight up and out of the socket. Do not touch the

contacts on the microprocessor socket.

Align the notches

of the microprocessor socket cover with the alignment keys

of the

microprocessor socket. Lower the socket cover straight down into the microprocessor socket

on the system board.

Note:

Your microprocessor socket and cover might look slightly different from the illustration.

d. Carefully press the socket cover straight downwards until it is secured into the socket.
