What you need

  1. PowerBook G4 Aluminum 17" 1-1.67 GHz Logic Board Replacement, Battery: adım 1, 1 resimden 1.

    • Orient the computer so that the side with the line of screws on it is away from you.

    • Use your thumbs to push both battery release tabs away so that the edge of the battery lifts up.

    • Lift the battery out of the computer.

  3. PowerBook G4 Aluminum 17" 1-1.67 GHz Logic Board Replacement: adım 3, 1 resimden 1.

    • Lift the memory door up enough so that you can get a grip on it, and slide it toward you, pulling it away from the casing.

    • Release the tabs on each side of the RAM chip at the same time. These tabs lock the chip in place and releasing them will cause the chip to "pop" up.

    • Pull the chip directly out from its connectors. If there is a second RAM chip installed, pop it out in the same manner.

    • This is a diagram of the trackpad ribbon clamp connector you will disconnect in the next step.

    • 1) With your fingernails, grasp the locking bar on either side slide it a small amount (about 1/16" or 2 mm) towards the battery.

    • 2) After disengaging the locking bar, slide the cable out of the connector.

    • For this step, you only need to move the connector about 2 mm. Pulling too hard or too far will damage the connector.

    • Loosen the trackpad connector by pulling the locking bar toward the battery housing, using the tips of your fingers.

    • Slide the trackpad cable out of the loosened connector.

    • When reattaching the trackpad ribbon cable, make sure that the orange cable is slid into the connector above the locking bar.

    • Note: When reassembling the case, the trackpad cable can get stuck below the slot to the motherboard. It's possible to nudge it out slowly by gently prodding it on either side with a small screwdriver. You don't need to use much force to do this. Eventually it will just pop back out and you can reconnect as per the instructions above. Also, note that the locking bar comes loose so if you see a little piece of plastic lying around when reassembling, that's what it is. :)

    • 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, 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. 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 raised copper heat conduit in three places. Clean the surface with rubbing alcohol.

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

    • Apply a new layer of thermal paste to all three chips.

    • 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.

    • When you place the logic board back in the computer, try not to move it around once the processor has come into contact with the newly-applied thermal paste.

All steps: photos seem to be missing (sept 21, 2015) from Steps 5, 8, 9, and 19. Any chance of getting them restored? Also, numerous pieces of yellow translucent scotch-like tape appear to hold cables out of the way, but are now dried out & non-sticky; can I use regular scotch-like tape for re-assembly, or is this some special stuff that needs to be replaced with like? If the latter, what is it called & where can it be acquired?

gary - Yanıt

You can get a kapton tape (the same stuff it was originally used)

Any chance of suitable thermal paste for GPU and chipset? The original is much thicker and feels more like liquid thermal pads than paste. It is a white stuff...
