    • Remove the four Phillips screws from the memory door.

    • Slide the memory door away from the memory compartment.

    Do you actually need to remove any of the screws on the underneath if you're just replacing a PRAM battery, or a hard drive? Aren't those only required if you're taking the whole logic board out?

    • 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).

    I found that the T6 was too small but a T7 worked, with a little push downward to make it sit inside the hex head.

    • 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.

    I've opened the G4 four times. The official Apple way outlined above is vastly superior to the paper clip method. When you lower the screen side of the deck, a little bit of pressure toward you will easily release the clips. Definitely begin with the back (screen side) of the deck where you just remove the two T-6 screws.

  9. PowerBook G4 Aluminum 15" 1-1.5 GHz DC & Sound Card Replacement: passo 9, imagem 1 %32
    • 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.

    This could really use a diagram to show exactly how the clip is structured. I didn't realize the clip was between the front of the case and the back support it attaches to, and it needs to be pried off that back support. (Evil Apple design - would it really hurt to have a screw underneath?). Overall these guides are fantastic! I just replaced a hard drive, and it worked great. And I LOVE the screw guide at the back - brilliant idea!

    isonno - Responder

    Apple official disassembly guide suggests instead to lift the upper case from the back up to 45 degrees. Then while lowering it back gently wiggle the upper case and it does disengage the latches. No tools required, no risk of bending the case.

    John - Responder

    This method worked perfectly for me. Lift at 45 degree angle and wiggle as slowly lower and it popped right off.

  10. PowerBook G4 Aluminum 15" 1-1.5 GHz DC & Sound Card Replacement: passo 10, imagem 1 %32
    • 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).

    I was able to easily release the latch by putting the spudger in the optical drive slot, and gently prying up. You can see the three holes where the upper case clips in above the drive, and the clips are accessible through those holes from the optical drive slot.

    ryan64 - Responder

    "Forward" (step 10) means toward the front. I was not able to release the latch this way. However, I did eventually release all three latches at once by very slightly lifting the rear of the cover and pressing the cover back toward the screen.

    It is not necessary to remove the trackpad and keyboard cables (steps 12, 13, and 14) to replace the hard drive.

    colleenthompson - Responder

    I've done several of these before, but today it was a bear to accomplish. I finally did it by inserting a dental pick through the optical slot and pulling forward to release the clip. In case it will help someone else, pictures of the clip are at Devil Clip.

    colleenthompson - Responder

    I did not find any clip to disengage to remove the top piece. I would like to have seen a picture of the clip after the the top was separated.

    Oh, well. This guide is probably not much use to anyone any more.

    • 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.

    The top assembly for the A1138 model (1.67MHZ high res) does not have two ribbon cables to connect to the logic board as pictured.

    • Remove the orange tape securing the trackpad ribbon to the logic board.

    • Disconnect the trackpad ribbon from the logic board.

    If you are just replacing a hard drive, you do not need to remove either the trackpad or the keyboard cables! They will not be in the way at all. Save yourself a headache.

    dougcabot - Responder

    I agree - removing the cables is not necessary. I didn't even have a keyboard cable on my machine.

    macbaen - Responder

    i agree, too:

    steps 12 to 14 are NOT necessary for replacing the harddrive!

    neither are 17 and 18!

    instead:

    after 10 continue with step 15.

    instead of 17 and 18: free the hd carefully

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

    • 1) With your fingernails, grasp the locking bar on either side and pull up a small amount (about 1/16" or 2 mm).

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

    Be very careful! The clasps holding the black strip are extremely fragile and can snap very easily.

    In fact it is possible to get to your hard drive and replace it without having to detach this ribbon at all and I would advise that if all you are doing is replacing your hard drive then skip this step.

    ChrisT4 - Responder

    My laptop did not have the big gray keyboard ribbon but a short white one with a blue stripe at the end. Anyone knows if this is just a different setup?

    afido - Responder

    my g, 15", 1.5Ghz pbk didn't have this cable at all. It's short white kbd cable attached to the trackpad, and it's orange ribbon cable (only) attached to the logic board as in step 12. lucky me.

    gogreens - Responder

    Yes, the note about skipping this step should be up there, front and center. I followed this step and broke the bit of plastic. Now it's re-fastened with a piece of electrical tape, but I am annoyed because it was totally unnecessary to do that. How do we edit the front page to at least say "OPTIONAL" for this step?

    Focus Fusion Society - Responder

    There should be a note on this to say this step is OPTIONAL. I followed instructions as written, broke the little plastic piece, and have taped it back together with electrical tape. But after replacing the hard drive, I see it was totally unnecessary to take this step. It's a high risk step, people should be warned.

    Focus Fusion Society - Responder

    the diagram is a bit confusing, and the text is a bit confusing for non english speakers. when it said pull up a small amount, i thought you have to try and lift it from the motherboard. all you have to do is move the black plastic bit towards the screen with your fingernails and the broad thing plastic keyboard cable comes off.

    • Loosen the keyboard ribbon clamp by pushing the thin black piece toward the screen, using the tips of your fingers.

    • The black piece is very fragile and easily broken. Use care when separating it from the main socket.

    • Slide the grey keyboard ribbon out of the loosened connector.

    • Remove the upper case from the computer.

    My machine didn't have a keyboard ribbon.

    macbaen - Responder

    Watch this step carefully! The release mechanism pushes back slightly, parallel with the surface of the logic board. You may want to gently use a sparger rather than your thumbs if you have big fingers. This is a very delicate connector. Work one side slightly then the other. The good news is that it does not offer any resistance.

    wcwirla -

    I've found, however, that it's not necessary to remove the cables and thus risking breaking these fragile parts. The still-attached keyboard can simply be rested against the screen/lid of the machine while the rest of the work is done.

    my airport antenna cable has no connector and it doesn't run under the Airport ribbon cable, but instead runs under the PCMCIA card slot to god knows where. urgh, am wondering if I'm following the right guide for my g4, 15: 1.5Ghz Pwrbk.

    gogreens - Responder

    It WAS the right guide, but my machine was missing an Airport cable connector, so I had to remove a half-dozen screws and a nut, loosening some black plastic that was screwed under the modem card, allowing access to remove the PCMCIA receptor (tricky getting it unhooked from the card ejector button), then removing the Airport card in order to unplug the cable.

    • Disconnect the indicated 14 cables from the logic board, starting in one place and moving around the board.

    When reassembling you might want to remember to reconnect the battery cable BEFORE tightening the logic board in place.

    Same goes for the cable from the power supply.

    Both can be done afterwards but it's a pain, better done before securing the board in place.

    • Remove the following 12 Phillips screws from the logic board:

    • Six 4 mm around the edges of the logic board.

    • Two 5 mm securing the right speaker to the logic board (move the speaker off of the logic board).

    • Three 6 mm with wavy washers in the upper, left corner of the logic board.

    • One 4 mm underneath a black bumper in the back right corner of the logic board.

    • One 4 mm screw may not be present on some logic boards.

    I only found 5 red screws

    nic9 - Responder

    It really helps to remove the torx that clamps down the display ribbon cable, located on the display hinge. Removing it frees the display ribbon to be moved out of the way a little when you soon pull out the logic board.

    Mine was stuck like that too. I ended up getting a flathead screwdriver and carefully prying up on the edge of the logic board in the back and it came off with an awful sounding pop. It looks like the processor was attached to the heat sink with something that is probably thermal paste. It doesn't seem to be damaged, but I haven't been able to test it yet.

    You will have to gently work the area next to the fan housing... the key is to do it gently, small movements at a time. If using a flat head, (which you should probably not) make sure not to damage the PCB

    • 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.

    Note during reassembly:

    Be SURE to route the Airport antenna cable into the space between the fat Airport ribbon and the card cage, and make sure it's still there when you reinstall the logic board. That antenna cable can slip under the logic board during reassembly, a mistake that you probably won't notice until much later -- when you put the display back on and discover that the antenna connector coming from the display has nothing to plug into.

Note regarding re-assembly:

I disassembled the PowerBook to replace a faulty DC board and then began performing the steps in reverse to reassemble.

When I arrived at step 38 I realized that I needed to loosen the torx and hex I tightened in step 43 in order to properly align the holes in the DC / sound board to install the PC Card carriage. Once I had the holes lined up and the phillips reinstalled in the PC Card carriage I re-tightened the torx and hex and carried on counting down.

Many thanks for this excellent guide!

My Powerbook is now charging batteries again and hopefully won't shut off when it decides it's worked too hard for the day! :-)

My only note: I was impatient with the keyboard ribbon cable and didn't understand your diagrams until it was too late. I used a fingernail to try and release the left side clip (white plastic)... which I broke off, it's not a clip mechanism, just a spring retainer. you just need to release the black plastic bar in the back under the ribbon cable, there is NO CONNECTOR on the cable, it;s just sort of a pressure fit!

I got it back together and had to use a piece of tape to hold it together... hope that works, unless anyone has a better idea. This laptop won't do much traveling any more, so I hope it will hold.

I also scraped and reapply thermal paste to the GPU chip and the big apple chip in-between (3 total).

CPU temp is running at 59 deg Celcius... hoping that is good? More research is needed.

Many thanks again!

Well, my PB G4 charged batteries for ca. 1 hour just after the repair 2 weeks ago and then decided it had had enough and hasn't charged a battery since. I did notice it got very hot while charging batteries for that hour. I had scraped and reapplied thermal paste to all 3 of the of the chips on the mobo (CPU, GPU and the one in the middle), so I don't think it was due to that.

I have just replaced the PRAM battery, after determining with apple's guide that it was not able to hold a charge and reading that it can affect charging. Still not charging batteries! Tried two different 65 watt power supplies too. Uggggh. Any ideas?
