The ins and outs of replacing your upper case.

    • Remove the following 6 screws:

    • Two 10 mm T6 Torx screws on either side of the RAM slot.

    • Four 14.5 mm Phillips screws along the hinge.

  5. Remove the four 3.2 mm PH00 Phillips screws on the port side of the computer.

  6. Rotate the computer 90 degrees and remove the two 3.2 mm Phillips screws from the rear of the computer.

  7. Rotate the computer 90 degrees again and remove the four 3.2 mm Phillips screws from the side of the computer.

  8. Do not yank the upper case off quickly. The case is attached to the logic board via a ribbon cable. Lift up at the rear of the case 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. There are four plastic clips above the DVD slot, and another above and to the left of the IR sensor.  These clips can be very difficult to disengage without prying.  They can also be difficult to re-engage during reassembly.

    • Reassembly Tip: Press down firmly on the tip of the top case above the location of each clip until you hear a snap to reseat them in their slots.

    • Reassembly Tip: The two center DVD clips will rarely snap back into place properly without help, and downward pressure will instead simply deform the frame around the DVD slot. Support the frame by inserting a plastic spudger into the DVD slot directly under the clip location until it is snug, then press down until you hear the snap.

  10. Disconnect the trackpad and keyboard ribbon cable from the logic board, removing tape as necessary. Note: It is possible to replace the hard drive without disconnecting the keyboard from the chassis, but it will need to be held upright to keep it out of the way, while still allowing you both hands to work on the drive removal.

    • Be careful when removing the keyboard-trackpad ribbon cable to ensure that the rear of the upper case is disengaged from the area near the hinge. It is easy to accidentally bend the screw receivers on either side of the keyboard.

  17. Remove the 12 identical Phillips screws attaching the keyboard to the casing.
    • Remove the 12 identical Phillips screws attaching the keyboard to the casing.

    • There are six locking tabs along the back edge of the keyboard holding it in place. These tabs must be straightened before you can remove the keyboard.

  18. Slide the keyboard ribbon out of its connector.
    • Slide the keyboard ribbon out of its connector.

    • If the keyboard ribbon won't slide out, make sure that the black plastic flap holding the ribbon in place is vertical.

    • It is common for the small ribbon just beside the keyboard ribbon to wear out with use in this model. (Keyboard and trackpad would not work but power button will.) The solution is to apply pressure directly on that cable where it enters the flap (with a piece of plastic or a folded paper that is pushed against by the battery).

  19. Place the upper casing on its edge and use a spudger to push the keyboard away from the casing, poking the spudger through the central keyboard screw hole. Grasp the keyboard as it separates from the casing. Maintaining your hold on the keyboard, lay the casing flat and gently bow the keyboard until the two tabs on either side of the keyboard come free.

this part is actually called the "top case", and is referenced as such in Apple's part numbers and take-apart guides.

Just did this. The guide is great. A good mod. Caveats:

(1) Use good screwdrivers... Really. I've done this for years and made the mistake of impatience anyway. I used poor-quality ones (though the right size) and partly stripped screws... Long story short, I had to buy replacement screws and dremel off the heads of the originals (thus also unable to easily re-use old top case)

(2) If your computer's old, you might need some new tape or adhesive at a few points (for the old sticky covers).

(3) If your upgrading A1226 to A1260 to get the new multi-touch trackpad (works BEAUTIFULLY, by the way :)), consider buying the keyboard with the upper case. Swapping keyboards is a fair bit of work, another chance to strip screws, and then you need to re-label (or swap) some keys to reflect the new special functions (these are changed by the new top case controller). If you keep the old keyboard (as I did), a simple P-touch labeler can be used to make new labels over the old keys (or you can swap keycaps if you have them from the new keyboard). Bottom line... A much more elegant solution is to swap the keyboard at the same time.

(4) Take care reassembling new the DVD drive. It's easy to bend the top piece of metal down (the one that engages the clips) and your DVD can get stuck occasional ejecting. Very annoying. Maybe give it a little prophylactic bend upward.

Overall, very happy!! Awesome pictures in the guide.

Yet another way to get good life out of an old Mac. Had an original MacBook Pro 3,1, since upgraded to new mainboard (under warranty), 6GB RAM, new MB fans (thanks iFixIt), new 500GB hybrid flash drive, now multi-touch thanks to this! Running 10.7.2 easily, great return on a purchase in 2007.

Cheers to the iFixit community!

I had a problem that is so common that I would love to see it as a comment within the guide: I spend the better part of a long afternoon reassembling different top cases and cables with the result that trackpad and keyboard didn´t work but the power button did. Sometimes both were working for a few minutes and next time I would start up they would be dead again. Solution was: The small cable that fits into the trackpad / USB Controller and takes the trackpad / keyboard signal to the logic board has a widely documented tendency to loose touch with its connectors after a few years. What helps is to apply pressure on the end of the cable where it enters the controller below the trackpad. Easy to check with fingers. In the long run use a piece of a thick plastic card or cardboard to apply pressure from the battery direkt on that spot. Easy. And works like charm. After I was so close before giving up my Macbook Pro or buying another topcase. Please add that possibility to the guide as it is really common.
