-
-
-
Lift the DC-In board out of the computer by pulling up and away from you.
-
If there is a fan present, rotate the DC-In board slightly clockwise before easing it out at a slight angle in order to clear the fan clamp on top of it.

Disconnect the 5 indicated connectors from the logic board, removing tape as necessary.
-
Reassembly Tip: Reseating the logic board will be much easier if you use kapton tape to hold these five connectors out of the way until it is in place.
-
Caution: If taping the connectors back, be careful not to use tape with anything but very weak adhesive (i.e. kapton tape). Even electrical tape can pull the paint off the hinges when removed.

Close the display and pull off both clutch covers. You can use a non-metal flathead screwdriver if the clutch covers do not come off easily.
-
-
-
Open the back panel port cover and remove the four T6 Torx screws.
-
-
-
Open the display to a 90 degree angle. Rest the trackpad face down on your work surface and allow the display to hang over the edge. If possible, adjust your chair or worksurface height so the display will rest on your legs and the trackpad will lie flat on the worksurface.
-
Remove the four T8 Torx screws which fasten the display to the trackpad. The screw closest to the display data cable has a tapered head.
-
-
-
Grasp the metal heat exchanger and pull up and away from you. You may need to move the inverter cable on the right side of the computer in order to rotate the heat exchanger.

This walk through is almost useless: it makes something long and complicated out of something simple and easy. The only thing you have to take out is the logic board in order to access the back of the display attachments. The heat exchanger may stay in too. Just be careful with the screen wires.
Same here. This guide may be using imagery from the pre-A1025 model PowerBook G4 Titanium’s, which would explain this discrepancy.
