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

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

    • 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.

  8. 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 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).

    Edit

  9. 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 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.

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

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

    • Two 7 mm shouldered Phillips on the far sides.

    • 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.

    Edit

  12. 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.

    • 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.

    Edit

  13. 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.

    • 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.

Does not boot up and did not break or damage the cable to motherboard. Any suggestions? The cable looks as new. But keeps booting for many minutes with spinning wheel

Before you do this - might be worth checking to see that the insulating gasket in the magsafe port is intact. I was about to buy a new board when I noticed that the gasket was broken (I wouldn’t have noticed there was even a gasket unless it was broken).

Turned out for me it was just this insulating gasket in the outside of the port that was stopping it charging and I didn’t even need to open the back. When I found part of it still intact, I guessed partial insulation might be that causing a short. The gasket is made of very thin tape and sure enough when I made a copy and put that in, it charged fine on the new charger I had bought. The old charger is dead (on this and a friend's machine) so I presume it was fried shorting while I repeatedly tried to charge before. P.S. I made the copy by making an inverse template by pressing Blutac into the port and used that as a block to print an outline onto the tape.
