    • The ZIF cable is located underneath the bottom RAM slot. If your PowerBook has both RAM slots occupied, make sure to remove the RAM chip.

    • Use your fingernails to separate the ZIF cable lock away from its socket. (Move the two brown bits down 1mm)

    • The ZIF cable lock will move about a millimeter away from the socket before it stops (see picture 2). Do not try to remove the ZIF cable lock.

    The ZIF cable locks are the little grey pieces seen on the cable-side ends of the white bar. They will slide, as per detailed picture, toward the cable.

    • 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.

    in what direction does one move the ZIF cable lock? what/where is its socket?

    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.

    • Disconnect both of the following connectors from the logic board:

      • Sleep sensor cable.

      • Power button cable.

    • Be sure to pull only parallel to the face of the logic board, as pulling up on the socket will break it off the logic board.

    • When pulling these connectors away from their sockets, it is helpful to use your fingernails to pull on the ears at each side of the connector.

    • Starting near the keyboard, use the flat end of a spudger to help separate the adhesive as you peel back the track pad ribbon cable.

    • Be very careful as you are peeling the ribbon cable back because it is very fragile and easily torn.

    • Also be sure to not pull on the keyboard and backlight ribbon cables underneath the track pad ribbon cable, as they are also very fragile.

Excellent detailed instructions and cautions. Even the magnified pictures are very good. A bit more complicated than a Dell or Toshiba. Mahalo.
