    • Power down your Mac mini, disconnect all of the cables, and flip it over.

    • Insert the Jimmy into the crack between the aluminum top housing and the plastic lower housing.

    • The Jimmy should reach a stop about 3/8" down.

    • Gently bend the Jimmy outwards to pry the crack open a little larger and lift the lower housing up a small amount.

    • There are several plastic clips on the lower housing that fit into a channel in the aluminum top housing. Your goal is to use the Jimmy to push these clips inward enough to free them from the channel, while gently pulling up on the lower housing.

    • Once you have the first side free, rotate the Mac mini and start prying up on the front edge.

    • Use the same prying motion to both bend the clips inward and lift the lower housing up out of the top housing.

    • You may need to move the Jimmy along the edge to pry up all of the clips. Be patient and do a little bit at a time.

    • Keep working around the perimeter, freeing the clips along the final edge.

    • Flip the Mac mini back over and lift the top housing off of the lower housing.

    • If your mini does not have Airport installed, then skip this step.

    • Grasp the Airport antenna board and lift it off of the two plastic posts holding it in place. You may need to push back the black plastic tab jutting through the lower left corner of the board.

    • Remove the yellow tape securing the power button cable to the black plastic framework.

    • Remove the three black Phillips screws securing the plastic framework to the logic board and lower case.

  10. Mac mini (PowerPC) Logic Board Replacement: 步骤 10 中的图像 1,1
    • Grasp the optical drive and mass storage unit in one hand and lift up enough so that you can see beneath it.

  11. Mac mini (PowerPC) Logic Board Replacement: 步骤 11 中的图像 1,1
    • If your mini has neither an Airport card nor a Bluetooth board, you can simply lift the optical drive up and away. Otherwise, you need to disconnect the Airport and/or Bluetooth antenna cables first.

    • With your free hand, pull the Bluetooth cable up from Bluetooth board and unplug the Airport antenna cable from the right of the Airport card. Caution: both of these connections are very small. When re-assembling unit after repair, you may want to remove the two screws holding the airport card to the assembly and lift the card up and out to re-attach the cables.

  12. Mac mini (PowerPC) Logic Board Replacement, Modem: 步骤 12 中的图像 1,1
    • Remove the two silver Phillips screws from the corners of the modem board.

  13. Mac mini (PowerPC) Logic Board Replacement: 步骤 13 中的图像 1,1
    • Pull the modem up from its connector. If it sticks, just wiggle it back and forth a bit as you pull up.

  14. Mac mini (PowerPC) Logic Board Replacement: 步骤 14 中的图像 1,1
    • Disconnect the RJ-11 cable from the back of the modem.

  15. Mac mini (PowerPC) Logic Board Replacement, Logic Board: 步骤 15 中的图像 1,1
    • Remove the two silver Phillips screws from the corners of the wireless interface board.

  16. Mac mini (PowerPC) Logic Board Replacement: 步骤 16 中的图像 1,1
    • Grasp the board at the front and back, and lift up on the front until the board pulls free of its connector.

  17. Mac mini (PowerPC) Logic Board Replacement: 步骤 17 中的图像 1,1
    • Pull back the black plastic latches on either end of the RAM chip.

  18. Mac mini (PowerPC) Logic Board Replacement: 步骤 18 中的图像 1,1
    • Grasp the RAM chip at the end opposite of the back ports, and pull directly up.

  19. Mac mini (PowerPC) Logic Board Replacement: 步骤 19 中的图像 1,1
    • Push the PRAM battery in and pull it up. You'll have to push the battery in further than you'd expect in order to get it to pop free.

    • When inserting the new battery, make sure the side with writing along the edges faces the black plastic holder. You should also insure that the metal connectors make contact with the battery (you can bend them forward if they do not).

  20. Mac mini (PowerPC) Logic Board Replacement: 步骤 20 中的图像 1,1
    • The cables you're about to remove are very fragile - do not pull directly on the wires. Instead, try to pry up the connector directly, using your fingernails or a small flathead screwdriver if necessary.

    • Disconnect the power button and sleep light cables from the logic board.

  21. Mac mini (PowerPC) Logic Board Replacement: 步骤 21 中的图像 1,1

You are supposed to replace the heat transfer pad on the bottom case when you remove the logic board. If this pad doesn’t make good contact with the GPU, you’ll get overheating and the unit will goto sleep after a short time.

My Mac Mini G4 is missing the screws for the HDD/DVD carrier and the one screw for the logic board. Can you tell me where I can buy these or give me specs so I can find replacements on eBay?
