Einleitung

Replace your sound card to regain audio functionality.

Werkzeuge

Ersatzteile

Schritt 1

Use your thumbs to push the two battery retaining tabs away from the battery.
The battery should pop up enough to rotate it toward yourself and lift it out of the lower case.

Schritt 2

Remove the three 2.3 mm Phillips screws securing the memory cover to the lower case.

Schritt 3

Lift the memory cover slightly and pull it toward yourself to remove it from the lower case.

Schritt 4

Remove the following ten screws:
Two 14.7 mm shouldered Phillips.
Three 12.3 mm Phillips.
One 3.8 mm T8 Torx.
One 6.8 mm T8 Torx.
Three 1.3 mm Phillips.

Schritt 5

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.

Schritt 6

Use the tip of a spudger to slide the trackpad ribbon cable out of its socket.

Schritt 7

Remove the four 3.4 mm Phillips screws from the PC card side of the PowerBook.
When replacing these screws, you must reinstall each screw in the correct order. Begin by installing the screw closest to the display hinge, and go out from there.

Schritt 8

Remove the four 3.4 mm Phillips screws from the DVI connector side of the PowerBook.
When replacing these screws, you must reinstall each screw in the correct order. Begin by installing the screw closest to the display hinge, and go out from there.
During reassembly, make sure to reinstall the two screws on the right into their appropriate locations, and not the DVI port anchor holes.

Schritt 9

Depress the display latch release button and open your display.

Schritt 10

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.

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.

Schritt 11

Use the flat end of a spudger to pry the sound card ribbon cable connector up off the logic board.
Move the sound card ribbon cable away from the face of the hard drive.
It is not necessary to disconnect the sound card ribbon cable from the sound card.

Schritt 12

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

Schritt 13

Remove the following four screws:
Three 11.1 mm T8 Torx.
One 3.9 mm T8 Torx.
Lift the hard drive out of the lower case.

Schritt 14

If necessary, remove the strip of tape covering the speaker cable.

Schritt 15

Pull the speaker cable connector straight up to disconnect it from the sound card.

Schritt 16

Remove the two T8 Torx screws securing the sound card to the lower case.

Schritt 17

Use the flat end of a spudger to pry the USB sockets away from the left edge of the lower case.

Lift the sound card slightly out of the lower case, minding the fragile lower portion holding the microphone connector.
The sound card is still attached to the PowerBook by the microphone cable.
