System board removal and installation - ThinkCentre M57 (type 6068, 6074, 9172, 6008) / M57p (type 9087, 9193, 9018, 9012)

This procedure describes how to remove and replace the system board.

Important: The heat sink and microprocessor might be very hot. Make sure these components are cool enough to safely handle before continuing this procedure.

Note: When replacing the system board you must also order a new retention module for the new system board. Make sure you have a retention module for the new system board before continuing with this procedure.

  1. Remove cover. See "Cover removal".
  2. Lift the fan duct off the heat sink fan.
  3. Remove any adapter cards installed in the PCI connectors.
  4. You might have to remove the drive bay assembly to access the system board. See "Accessing system board components and drives".
  5. 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".
  6. Remove the hard disk drive. See "Replacing the hard disk drive".
  7. Remove the screws that secure the system board to the chassis.
  8. Lift the system board out of the chassis.
  9. Remove the memory modules from the failing system board and install them in the same location on the new system board.
  10. Disconnect the heat sink and fan assembly cable from the system board. See the system board illustration for your machine type at "System board connectors".
  11. Remove the four screws securing the heat sink and fan assembly to the system board.

Replace board

  1. Lift the heat sink and fan assembly off the failing system board. Place the heat sink on its side so that the thermal grease does not come in contact with anything.

    Note: You might have to gently twist the heat sink to free it from the microprocessor.

  2. To remove the microprocessor 2 from the system board, lift the small handle 3 and open the retainer 1.

System board

Important: Touch only the sides of the microprocessor. Do not touch the gold contacts on the bottom.

  1. Lift the microprocessor straight up and out of the socket.

Lift the microprocessor

Notes:

a. Notice the orientation of the notches 1 on the microprocessor. This is important when reinstalling the microprocessor on the new system board.

Processor

b. Do not drop anything onto the microprocessor socket while it is exposed. The socket pins must be kept as clean as possible.

  1. 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.

  2. 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.

  3. Lower the microprocessor straight down into the system board socket of the new system board.

Lower the microprocessor

  1. To secure the microprocessor in the socket, close the microprocessor retainer and lock it into position with the small handle.
  2. Install the new retention module (if required) on the new system board.
  3. Install the heat sink and fan assembly on the new system board.
  4. Reconnect the heat sink and fan assembly cable to the system board. See the system board illustration for your machine type at "System board connectors".
  5. Install the new system board into the chassis and align the screw holes with those in the chassis. Insert and tighten the screws that secure the system board.
  6. Reconnect all cables that were disconnected from the system board.
  7. Reinstall the hard disk drive. See "Replacing the hard disk drive".
  8. Align the drive bay assembly with the two slots and rails on the sides of the chassis, reconnect the drive cables on the system board, and then slide the drive bay assembly towards the rear of the chassis until it snaps into position.
  9. Reinstall the front bezel.
  10. Reinstall any PCI adapter cards that were removed.
  11. Position the fan duct on the heat sink fan.
  12. Go to "Completing the FRU replacement".
