In my iBook G4 (Fr), there's no T8 Torx but nut driver.

Be careful, the rubber feet tend to jump out and get lost.

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

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

This part scared me, never in an iFixIt guide have I seen a warning like "trying times are ahead".

I used a plastic iPod opening tool and ran it around the seam in the same order pictured. I had the plastic off in less than a minute with almost no fuss.

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.

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.

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.

I found it easier and "safer" to use a spudge at the back as well (two on each side of the hinge)
