"Close the display and flip the computer over." ...Seems like this instruction ought to be at the beginning of step 1 rather than step 2. In step one, the display is already closed and the computer flipped over. In step 2, you just keep it in this position and proceed from taking the battery out to removing the rubber feet.

Don't use a screwdriver! I broke out one of them...

Creditcard, FIngernails would be fine.

Well, if you've had an iBook G4 this long, odds are the little rubber feet are falling off just from being looked at. Except the battery mounted one. That sucker is the Devils' Tower of little rubber feet.

I bought & used the tool kit that you sell for this repair. The 3 rings came off when the screws came out--maybe because the screw bit holder is magnetized.

I found T9's rather than T8's.

Breathe deeply. Trying times are ahead, but we promise the lower case does come off.

  • Push the thin rims of the lower case surrounding the battery compartment in, bending them past the tabs, and then lift up to free that corner of the lower case.

When I did this, it helped to start around the disc drive

I find that a stiff nylon guitar pick will work if you don't have a spudger.

I didn't find this step difficult at all. I have very short nails. I imagine a woman with long nails might have a problem grasping the rim and pulling up.

Definitely read the rest of the instructions now. I struggled at first... I was using my ipad with the step by step instructions and didnt scroll down past this photo, so I didnt see the sequence of how to loosen the tabs. in fact I didn't know where the tabs might be... Only discovered that part when I reassembled it. The spudger didn't work for me. Too soft, I used mostly a thin very small screwdriver.

There is a slot on the wall of the battery compartment that locks the lower case in place. Use a small flathead screwdriver to pry out the slot's lower rim and pull up on the lower case to free the slot from the tabs holding it.

Run a spudger along the seam between the lower case and upper case on the front of the computer to free the tabs locking the lower case. Pull up on the lower case and continue to use the spudger as necessary until you hear three distinct clicks.

Steps 7-9 were effortless for me.

Continue to run the spudger around the front right corner. There are two tabs on the port side of the computer, one near the front corner and one near the sound-out port.

There are three tabs over the optical drive that must be released before the lower case can come off. Slide the spudger into the lower case above the optical drive and run it toward the back of the computer until you hear three distinct clicks.

try using the spudger at the back near the vents. To be specific, on the left side of the hinge when faced upside-down. It's easier this way and it's described on Apple's official repair manual.

then put a library card or something between the outer enclosure and the optical drive enclosure then pull from the other side to free the casing

The front and sides of the lower case are now free.
  • The front and sides of the lower case are now free.

  • Turn the computer so that the back is facing you and pull the lower case up and toward you until the back tabs pop free.

  • It may be helpful to jiggle the case up and down.

Steps 10-12 were just as easy. I bought & used the Spudger, too.

this required a little more force than I felt comfortable with at first.

  • Have patience and follow the directions, the end result is up to you. In my case it worked. But I was a Technician TRW Automotive. and worked on Air Bag modules that was returned from customer's that needed them analyzed. I just retired after 26 years.

This is where things got interesting for me. I had 4 missing screws! I don't know if it came from Apple like that (highly doubtful) or if it was returned to me without the screws from the Apple Store repair I had done to replace the Latch (more likely, huh?).
