    • Use a coin to rotate the battery locking screw 90 degrees clockwise.

    • Lift the battery out of the computer.

    Also unplug the computer just before taking the two steps described above.

    • Your laptop should look approximately like this.

    Don’t we need to remove the screws before the next step?

    Remove the two long screws along the back edge, and the shorter screw in the middle. Torx T-8. Pry up the rubber feet, and unscrew the three Phillips screws that hold the feet in place. Putting the silver collars back requires a little bit of fiddling to get them oriented correctly so they sit flush with the bottom case.

    Step 10 should come after step 15.

    • Use a pin (or anything you like) to remove the three rubber feet from the lower case.

    • Remove the three 5.2 mm newly-revealed Phillips screws.

    Screw sizes are 2.5mm x 6mm flat low profile head or cheese head.

    this should be after step 12 no?

    This should be step 3.

    • Use a spudger or small flathead screwdriver to pry up the three metal rings that housed the rubber bumpers.

    • Remove the one 10 mm and two 20 mm hex screws using a 2mm hex. Alternatively, a T8 Torx screwdriver key will do.

    FYI, the two screws at the top of this picture are longer than the one in the middle of the case. Don't mix them up!

    Top screws are 20 mm, middle one is 10 mm. These have thread lock.

    The 3 long screws (not the ones under the rubber feet) are 2.5mm x 20mm metric. Head style is cheese head. i found replacements for these at ACE hardware, for about $0.08 each in a flat head drive style which IMO are better than the hex style that can easily be stripped.

    I'm using a T9 here as my T8 is way too small.

    Matt - Réponse

    Two of the hex screws here got stripped. Please, replace them ASAP and I would recommend not putting them back just to not risk making them stuck. I spent 30 minutes trying to get those two out.

    • Remove the two 4.2 mm Phillips screws on either side of the battery contacts.

    • 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.

  9. iBook G3 12" Lower Case Replacement: étape 9, image 1 de 1
    • 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.

    If your iBook's been opened many times (Like mine has been) then this piece may be broken.

    If it's cracked down the middle or a little off, what you'll want to do is use your bent paperclip from a few steps later (or another screwdriver) and pull the second piece away from the shell when you start lifting. should pull right out

    • 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.

  11. iBook G3 12" Lower Case Replacement: étape 11, image 1 de 1
    • 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.

    isn’t this step out of order? It belongs much later I think

    panakabear - Réponse

    This should be step 4.

    • Once the front and sides of the lower case are 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).

    You might wanna use your spudger to pry up those back tabs to. You might break the bottom case just wiggling around waiting for it to pop loose.

    The orange screw on my machine has no head on it and is simply a flat surface. There is no way to remove it and consequently I completely trashed my unit attempting to remove the top cover.

    There went a few bucks all for nothing as I had a spare HD sitting here ready to put in!

    Calum - Réponse

    Be aware that you may need to use a spudger at the front of the computer to separate the metal shield from the bottom case.

    • Remove the small greasy springs with white plastic caps from either side of the battery contacts.

    Clean the springs and put them back, hopefully without breaking the small plastic pieces on the top of each spring. One of mine broke off and the other one was already missing. Poor design.
