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

Lift the battery out of the computer.

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

The screws are captive to the metal memory cover.

Lift up on L-shaped memory cover, slide it to the right, and lift it out of the computer.

Remove the following 3 screws:

• One 11 mm Phillips #00 in the middle of the case.
• Two 14.5 mm Phillips #00.

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.

Remove the following 3 screws from the rear wall of the battery compartment:

• Two 3 mm Phillips #00.
• One 4 mm Phillips #00 on the right side.

When reinstalling these screws, it may be helpful to push down on the lower case to line up the screw holes.

Remove the two 6 mm Phillips #00 screws from either side of the right wall of the battery compartment (not the ones closest to the battery connector).

Remove the four 3 mm indicated Phillips #00 screws from the front wall of the battery compartment. When working from the left, remove the 2nd, 4th, 7th and 9th screw.

Remove the following 4 screws from the back of the computer:

• Two 7 mm Philips on the far sides.
• Two 10.5 mm Phillips toward the center.
• Do not over-tighten these; you can cause the case to distort.

Remove the two 5.2 mm shouldered Phillips #00 screws from the optical side of the computer.

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

Starting near the display and working around to the front of the computer, pry up on the upper case. It is held with clips on the right above the optical drive. These will release with some firm lifting pressure.

Be careful when prying up the upper case. It's very easy to slice open a fingertip and thus provide the blood sacrifice the Mac gods sometimes require of those who insist on doing their own repairs.

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

If you have trouble getting the clips to release, be careful that you are not prying the plastic top of the upper case away from its metal frame.

While holding up the upper case, use a spudger to pry up the orange trackpad and keyboard cable from its connector.

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.

Remove the following 3 screws from the left hinge mount:

• One 6 mm smaller diameter Phillips from the right side.
• One 6 mm larger diameter Phillips from the middle.
• One 10 mm Phillips from the left side.

Lift the hinge mount and attached plastic dust cover out of the computer.
