Before continuing, place a soft cloth on your work surface to rest the computer on. Turn the G4 over, making sure the DVD drive doesn't fall out.
Carefully peel the adhesive strip away from the DVD drive. The plastic dust shield covering the DVD drive is easily damaged. Try to start at the four corners and work toward the center.
Carefully lift the logic board up and pull it away from you. The logic board may catch on the back panel ports liner. If this occurs, use a spudger or non-metal tool to free the logic board.
This step requires some force, but if the logic board will not come up, make sure you have removed all screws and connectors necessary.
Remove the logic board from the computer.
Performing the following steps incorrectly can easily damage the display and render it inoperable. The multicolor display data cable is especially fragile.
Position the display at a 45 degree angle and rest the computer on a cloth with the back panel ports facing up. Remove the two T8 Torx screws from each clutch cover.
Open the display to a 90 degree angle. Rest the trackpad face down on the work surface and allow the display to hang over the edge. If possible, adjust your chair or work surface height so the display will rest on your legs and the upper case will lie flat on the work surface. If you cannot make this adjustment, you can remove the display with the screen closed. We recommend removing the display with the screen open in order to avoid changing the position of the hinges once the display has been removed.
