Starting near the display, lift the upper case straight up off the lower case, minding any cables that may get caught.
Sometimes the "tags"/"lugs" that are around the edge of the top & bottom frame, be careful not to bend them as when putting back the covers they will not merge. I used a screwdriver to poke through the hole the screw was supposed go in & push against the "inside nut" to let the tag from the top slide down between the 2 tags. The "inside nut" is like the one right next to the ribbon cable as shown in Dia.14. The screws are from Dia. 7&8.
When putting the machine back together (following steps in reverse), make sure the trackpad ribbon cable comes through the underside of the computer — there is an opening that the cable needs to go through and you will want to “thread the needle” with the cable before securing the upper case again.
At the end of these instructions, Jimbo Combo also mentions this, but it should be repeated.
Because the trackpad/keyboard cable is part of the top face/keyboard/trackpad assembly, it’s actually a PITA when doing reassembly.
One way to make this step simple is to do the following:
1. straighten the Zif cable removing all of the bends that is probably has in it.
2. Start putting the top face/keyboard/trackpad assembly on, starting with the edge AWAY from the display.
3. Place the laptop on it’s side, and thread the cable through the opening, using tweezers if necessary so that it fully goes through the opening in the case.
4. Place the laptop back to the way it was and proceed.

Use the flat end of a spudger to pry the optical drive cable connector up off the logic board.

Use your fingernail and the tip of a spudger to raise the ZIF cable lock slightly up off its socket.
