G4 Aluminum 17" 1.67 GHz (HR) DC-In Board

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.

Where could I get a whole replacement for this connector ? Mine came off the motherboard

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

Remove the strip of tape covering the speaker cables.

Schritt 12

Disconnect the RJ-11 cable from the modem.

Schritt 13

Use your fingernails or the tip of a spudger to separate the ZIF cable lock from its socket.
The ZIF cable lock will move about 1 mm and stop. Do not attempt to completely remove the ZIF cable lock.

Schritt 14

Pull the DC-in cable out of its socket.

Schritt 15

Peel the DC-in cable off the adhesive securing it to the lower case.

Schritt 16

Use the tip of a spudger to remove the piece of foam tape from the channel on the side of the left speaker.
De-route the cables from the channel in the left speaker.

Schritt 17

Remove the single T8 Torx screw securing the left speaker to the lower case.
Lift the left speaker from its rear edge and maneuver it out of the lower case, minding the cables sitting in the channel near the front edge of the left speaker.
Set the speaker next to the lower case.

Schritt 18

Pull the DC power cable connector straight up off the DC-in board.

Schritt 19

Remove the two T8 Torx screws securing the DC-in board to the lower case.
New line.

Schritt 20

Pull the DC-in board away from the side of the lower case to separate the ports from their bezel.
Lift the DC-in board out of the lower case.

Schritt 21

Use your thumbs to slide the RJ-11 board slightly away from the DC-In board.

Schritt 22

Use the flat end of a spudger to continue removing the RJ-11 board away from the DC-In board.

Schritt 23

Use the flat end of a spudger to separate the ZIF cable lock from its socket.
The ZIF cable lock will move about 1 mm and stop. Do not attempt to completely remove the ZIF cable lock.

Schritt 24

Pull the DC-in board cable straight out of its socket.
DC-in board remains.

This guide was perfect, I successfully repaired my machine with a replacement board.

I just wanted to make two comments that might help someone else following this guide:

* (Step 20) When inserting the replacement board, I had a bit of trouble getting it to sit in place; it would go in, but even when pushed, was about 1.5mm out of position. After a while I realised there was a tiny plastic rib under the board that seemed to be interfering. I pinched the plastic rib with pliers and then my board slotted fully into place.

* (Step 10, when reassembling) When replacing the top half on to the case, make sure the trackpad ribbon cable is poking through the small slot in the base chassis! First time I reassembled, the ribbon was folded up and I had to re-separate the case to poke it through.
