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.

Шаг 6

Remove the following 3 screws from the rear wall of the battery compartment:
Two 3 mm Phillips #00. (A1181 has three 3 mm screws and one 4 mm.)
One 4 mm Phillips #00 on the right side.
When reinstalling these screws, press gently on the lower case to line up the screw holes.
These screws easily strip, so be careful while taking these particular screws out.

Шаг 7

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).

Редактировать

Шаг 8

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.

Редактировать

Шаг 9

Remove the following 4 screws from the back of the computer:
Two 7 mm shouldered Phillips on the far sides.
Two 10.5 mm Phillips toward the center.
Do not over-tighten these; you can cause the case to distort.

Редактировать

Шаг 10

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.

Редактировать

Шаг 11

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.

Редактировать

Шаг 12

While holding up the upper case (from the bottom or the top), use a spudger to pry up the orange trackpad and keyboard cable from its connector.
Take care to pry between the black socket and the white connector. You might have to pry on both sides for it to release properly.
Do not pry from the bottom or the top, but from the sides.
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.

Шаг 17

Lift the heat sink out of the computer, making sure that the black tape doesn't catch on the heat sink.
If you need to mount the heat sink back into the laptop, we have a thermal paste guide that makes replacing the thermal compound easy.
