Replacing the system board assembly
  1. Turn off the computer and allow the computer to cool for one hour.
  2. Open the computer cover. See "Opening the cover".
  3. Pivot the drive bay assembly upward to gain access to the system board.

Pivoting the drive bay

  1. While holding the rear of the computer chassis down, pull upward on the handle provided to remove the PCI riser assembly and any adapters that are currently installed.

Removing the PCI adapter

  1. Disconnect the cables connected to the system board.
    • For ThinkCentre A52 (type 8155, 8156, 8157, 8158, 8159, 8160) and M52 (type 8099, 8116, 8215, 9210, 9211) systems, see "System board diagram".
    • For ThinkCentre A52 (type 8289, 8298, 8328, 8341, 8344, 8382) systems, see "System board diagram".


    Important:
    Note the cable routing. It is important to route the cables the same way after you install the new system board.

  2. Using the two blue handles provided, lift the system board assembly out of the computer.

Lifting out system board

Note: You will have to tilt the system board assembly and move it around the edge of the power supply assembly to remove it from the computer.

  1. Place the defective system board next to the new system board on a clean, flat surface.
  2. Release the lever holding the microprocessor heat sink.

Releasing the microprocessor

  1. Remove the heat sink from the system board.
  2. Release the lever 1 for the microprocessor retainer 2 securing the microprocessor 3 and pivot the retainer upward to the open position.

Removing the microprocessor

  1. Use the vacuum pen 1 to lift the microprocessor straight up and out of the socket.

Vacuum pen

Important: Do not touch the gold contacts on the bottom of the microprocessor. Use the vacuum pen provided to remove and install the microprocessor. If you must touch the microprocessor, touch only the sides.

  1. Notice the orientation of the notches 1 on the microprocessor. This is important when installing the microprocessor on the new system board.
    Removing the processor
  2. Do not drop anything on the socket while it is open. Keep all contacts 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.
  2. 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, do not tilt the microprocessor when installing it into the microprocessor socket.
  3. Use the vacuum pen 1 to lower the microprocessor straight down into the microprocessor socket.

Removing the microprocessor

  1. Lower the microprocessor retainer and secure it with the lever.
    Note: There will be a black plastic cover on the microprocessor retainer to protect the socket on the new system board. When you lock the microprocessor in position, remove the black plastic cover. Place the black plastic cover on the microprocessor retainer of the defective system board.
  2. Install and secure the heat sink on the microprocessor.
  3. Remove the memory modules from the defective system board, and install them on the new system board. See "Replacing a memory module". Return here after installing the memory modules and continue to the next step.
  4. Install the new system board assembly into the computer chassis by aligning the tabs on the rear of the system board with the slots in the rear of the computer chassis. Slide the system board toward the rear of the chassis.
  5. Reconnect the cables that were disconnected from the system board. Make sure all cables are routed correctly.
