  3. Unscrew the three evenly-spaced Phillips screws from along the rear wall of the battery compartment.

    • Unscrew the three evenly-spaced Phillips screws from along the rear wall of the battery compartment.

    • The screws are captive to the metal memory cover so you cannot lose them.

    • Using The Flexible Extension sold by iFixit will help with this step.

    • Two 14.5 mm Phillips #00 (Head: 5mm dia. x .75mm thick)

    • If the screws stick in the case, you can use a magnetized screwdriver to draw them out.

    • The shorter of the three screws goes in the middle.

  7. Take extra caution with these screws as they can strip easily!

    • Take extra caution with these screws as they can strip easily!

    • You could use a flexible extension to minimize stripping.

    • One 3 mm Phillips #0. (Head: 2.75 mm. dia.)

    • Two 4 mm Phillips #0 on the either side. (Head: 2.75mm dia.)

    • Two 7.25 mm Phillips #00, with Shank (2mm dia. x 3.75 mm len.) (Head: 3.2 mm. dia. x .5mm thick)

    • During reassemble, install the two longer screws go on the inside, and the two shorter screws go on the outside.

  11. Remove the two Phillips screws from the optical drive side of the computer:

    • Remove the two Phillips screws from the optical drive side of the computer:

    • Two 5.2 mm Phillips #00, with shank (2.3mm dia. x 3.25 mm len.) (Head: 3.2 mm. dia. x .5mm thick)

    • It is not necessary to remove the similar screws on the other side of the computer.

  12. There's a trackpad and keyboard ribbon cable connecting the upper case to the logic board, so don't pull the upper case off entirely just yet.

    • There's a trackpad and keyboard ribbon cable connecting the upper case to the logic board, so don't pull the upper case off entirely just yet.

    • Starting near the display and working around to the front of the computer, pry up on the upper case. A plastic opening tool, expired plastic credit or similarly-thick card, or a medium hard guitar pick may help you to do this.

    • The upper case is likely to stick at the connection above the front edge of the optical drive. If this happens, first free all other sides, then proceed to pull upward on the upper case from either side of the optical drive opening.

    • If you stand the base on end to get a better look, you may displace the four grey plastic clips that hold the right side of the upper case in place. Don't panic. They slide into slots at the top rightmost edge of the lower frame, above the front edge of the optical drive.

    • During reassembly, make sure the clips on the right side click firmly into place. They're different from the clips on the left side, and so normally they require a little more pressure to click into place more firmly.

  13. While holding up the upper case open, pull up the black tab, on the connector end of the silver cable, away from the connector's socket on the logic board. If there is no black tab, you can also use a spudger to gently pry the connector out of its socket on the logic board. This connector is tall, so be sure to pry straight up. If you happen to break your upper case cable when removing the upper case, we stock the cable individually and we have a guide that makes replacing it easy.

    • If you happen to break your upper case cable when removing the upper case, we stock the cable individually and we have a guide that makes replacing it easy.

    • While you have the upper case removed, it's a good time to remove dust, hair, etc. It's best to use a can of compressed air, though if you use a brush, make sure that its bristles are made of a material (usually animal hair) that doesn't generate static electricity, which can destroy electronics.

    • Upon reassembly, there are 4 grey plastic clips installed in slots running along the top of the frame in front of the optical drive (refer to second and third pictures). These clips must be installed in their slots for their mating tabs on the underside of the right side of the upper case to snap into them.

  14. Disconnect the three antenna cables from the Airport card on the left side of the computer. Gently pull an antenna cable straight up to remove it. Notice the order of the antenna cables from left to right is black, blue, and gray.

    • Disconnect the three antenna cables from the Airport card on the left side of the computer. Gently pull an antenna cable straight up to remove it.

    • Notice the order of the antenna cables from left to right is black, blue, and gray.

    • If you have a MacBook Core 2 Duo Santa Rosa/Penryn, there are only two antenna cables on the Airport card--black on the left, and gray on the right.

This guide was great but I have the new Unibody MacBook Pro 13-inch, 2.26GHz. Does anyone know how to replace the wireless card in this new type of MacBook? Thanks!
