Text of the audio portion of this movie

To remove the system board:

  1. Place the system in the service position
  2. Turn off the system and all attached peripheral devices.
  3. Disconnect all power cords and all external signal cables. For easier access to components, place the system on its side. This is the recommended service position.
  4. Remove the side cover. Press the cover-release button on the right side cover, slide the cover to the rear and lift it off.
  5. Remove the drive cage. Remove the power cables for the drives. Remove the SATA signal cable from the disk.
  6. Remove the signal cable from the diskette. Remove the thumb screw to release the cage from the chassis.
  7. Slide the assembly to the rear and out of the system.
  8. Remove the adapter card. Press down on the release the latch and rotate the card retaining bracket to the open position.
  9. Grasp the adapter cards by the ends and lift it out of the connector. Here’s a close up the adapter retaining release bracket.
  10. Remove the battery. Release the battery latch and lift it out of the holder.
  11. Remove the DIMMs. Push out on the two latches.
  12. Lift the DIMM out of the socket and place it on a static protected surface.
  13. Use the same procedure to remove any remaining DIMMs. Note: Cables have been repositioned for viewing purposes only.
  14. Remove the fan baffle and processor. Squeeze the two tabs on the top of the baffle and lift out.
  15. Remove the heat sink. Prior to removing the heat sink, you should power on the system for a few minutes to soften the thermal layer, so that the heat sink can easily be removed.
  16. Rotate the heat sink release lever to the open position.
  17. Pivot the heat sink up to disengage the bottom end of the heat sink from the lip on the heat sink retention bracket.
  18. Rotate the processor release lever to the open position.
  19. Open the processor retainer. Place the vacuum tool in the center of the processor and squeeze the tool to apply suction to the processor, and then gently lift the processor straight up from the socket. Always place the protective cover over the processor contacts when the processor is out of the system. Use care not to touch the contacts, because any contamination can damage them. If the processor is going to be removed for any length of time, you must install a dust cover to protect the socket from contamination.
  20. Place the dust cover over the processor retainer and press into place. Close the processor retainer.
    Note that when you replace a processor, you must return the processor replacement tool, along with the replaced processor in the packaging provided. The replaced heat sink should be disposed of locally.
  21. Remove the system board. Remove the following cables:
    1. Front fan
    2. P2 Power
    3. P1 Power
    4. Front panel card
  22. Remove the seven screws securing the system board to the chassis.
  23. Slide the system board to the front of the system to release it from the tabs in the chassis and lift the system board out.
