  7. PowerBook G4 Aluminum 15" 1-1.5 GHz RJ-11 Board Replacement: step 7, image 1 of 1
    • Turn the computer over and open the display.

    • Remove the 4.2 mm 1/16" H 1.5 hex screws in either corner, next to the display (a T6 Torx driver will also do the job nicely).

  8. PowerBook G4 Aluminum 15" 1-1.5 GHz RJ-11 Board Replacement: step 8, image 1 of 1
    • This step covers the hardest part to get inside this computer. Take a deep breath and think happy thoughts.

    • Grasp the back corners of the upper case and pull up, disengaging hidden tabs on the sides. Do not pull the upper case off yet; you still need to free tabs in the front of the case.

    • The seam is beneath the plastic molding on the upper case.

  9. PowerBook G4 Aluminum 15" 1-1.5 GHz RJ-11 Board Replacement: step 9, image 1 of 1
    • There is one latch that stops you from pulling the upper case right off, located on the left side of the optical drive slit. To free the upper case, you will be pulling a thin metal latch toward you, freeing it from the clasp holding it in place.

    • Pry up the left side of the upper case slightly with your hand and wedge a spudger into the seam between the upper case and lower case.

    • Leave the tool in place applying pressure to the upper case for the next step.

  10. PowerBook G4 Aluminum 15" 1-1.5 GHz RJ-11 Board Replacement: step 10, image 1 of 1
    • Place enough pressure on the upper case to allow you to slide a tool just within the seam between upper case and lower case as shown in the picture. A dentist's hook, push pin, or similar tool will work.

    • Do not yank the upper case off as soon as you free the clasp. The case is attached to the logic board via two ribbon cables.

    • Delicately slip the tip of your tool behind the silver metal latch and pull it forward while pulling up on the case. This may take some effort.

    • Alternatively, you can free the clasp with a small flathead screwdriver through the CD slot. The clasp is 1-3/16 in (3cm) from the left side of the slot. Use the screwdriver to lift out (or press back) the felt lining; then use the screwdriver to pull the clasp (shiny metal) forward to free it from the catch behind it (dull metal).

  11. PowerBook G4 Aluminum 15" 1-1.5 GHz RJ-11 Board Replacement: step 11, image 1 of 1
    • 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.

    • Rotate the upper case up and toward the screen, so that the upper case rests against it.

  12. PowerBook G4 Aluminum 15" 1-1.5 GHz RJ-11 Board Replacement: step 12, image 1 of 1

    • 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. The following steps refer to replacing the thermal paste between the processor and heat sink; follow these steps only when you are ready to place the logic board in the computer.

    • Use a firm plastic edge to scrape the thermal material off the processor.

    • For more advanced instructions on this procedure, see our Applying Thermal Paste Guide.
