Rotate the computer 90 degrees clockwise, so that the power receptacle faces you.
Remove the three 3 mm Phillips screws.
When replacing these screws, you must place each screw in the correct order. Begin by installing the screw closest to the display hinge, and go out from there.

Grasp the back corners of the upper case and pull up. Do not pull the upper case off yet; you still need to disconnect the keyboard and trackpad cable.
Lift the back of the case up and work your fingers along the sides, freeing the case as you go. Once you have freed the sides, you may need to rock the case up and down to free the front of the upper case.
Two cables still connect to the logic board and must be removed before pulling the board entirely out of the computer.
Use a spudger to gently (very gently) pry up the left side of the logic board.
If the logic board does not immediately come free, it may be necessary to soften the thermal paste between the logic board and heat sink. You can soften the thermal compound using a hairdryer. Move the hairdryer back and forth between the two fans about one inch above the logic board for one minute. At this point, the logic board should now come free easily.
Grasp the logic board at the left edge with one hand and at the thinnest section with the other hand. Lift the left edge of the board up to approximately a 30 degree angle (if you don't have your protractor handy, just lift until the DVI port clears the right hinge).
Once the logic board clears the ports, slide it out to the left.
Important: when you reinstall a logic board, you'll need to replace the thermal paste that goes between the processor on the logic board and the heat sink. Failure to remove the old paste and apply a new layer can cause the computer to overheat and sustain damage.
To properly reassemble your PowerBook, you'll have to clean off and replace the old thermal compound. Use our Applying Thermal Paste Guide to prepare the processor and heat sink surfaces.
Use a firm plastic edge to scrape the thermal material off the processor.
When replacing the logic board, make sure all cables are routed around and above - not under - it, and to connect the two cables that do go beneath before pushing the board into place.
Place the logic board back in the computer, trying not to move it around once the processor has come into contact with the newly-applied thermal paste.
Insert the flat end of a spudger between the front display bezel and the plastic rim attached to the rear bezel near the lower left corner of the display.
Do not insert the spudger between the plastic rim of the rear display bezel and the aluminum rear display bezel plate.
Repeat the previous steps to separate the right side of the rear display bezel from the display.
Use your spudger to pry the plastic retaining clips on the rear display bezel over the raised aluminum tabs on the front display bezel.
At this point, the clips on the left and right edges of the rear display bezel should be free from the raised aluminum tabs on the front display bezel. If they are not, use a spudger to pry them past the front display bezel.
Slightly lift the lower edge of the rear display bezel and push it toward the top edge of the display, releasing the clips along the top edge of the rear display bezel.
Rotate the rear display bezel toward yourself and lay it flat on the table.
The clutch cover is constructed from aluminum and is held on to the clutch hinges with metal clips that require a good deal of force to remove. Proceed with caution.
Use your thumbs to push the clutch cover away from the clutch hinges.
While pressing with your thumbs, rotate the clutch cover toward yourself about its long edge to pop it off the clutch hinge.
It may be necessary to wiggle the clutch cover while pressing it away from the clutch hinges to release the retaining clips.
Repeat this process for the other side of the clutch cover. Once the clutch cover is completely free from the clutch hinges, lift it off the front display bezel.
When replacing the clutch cover, be sure to route the display data cable so that it is inside the clutch cover and extending out the end between the hinge and the display frame.
