How to access the PowerBook G4 Ti DVI Modem Filter Board.

  1. Locate the battery release tab on the underside of the G4.
    • Locate the battery release tab on the underside of the G4.

  2. Turn the keyboard locking screw located in the middle of the keyboard so that it is parallel to the space bar. A half turn from parallel to parallel will unlock it. Another half turn will lock it again.
    • Turn the keyboard locking screw located in the middle of the keyboard so that it is parallel to the space bar. A half turn from parallel to parallel will unlock it. Another half turn will lock it again.

    • Pull the keyboard release tabs toward you and lift up on the keyboard until it pops free.

    This is not a screw, it is light transmitting plastic for the num lock light

    • Rest the keyboard face down on the trackpad area.

    • Disconnect the keyboard connector from the logic board.

    The keyboard connector can be very tightly connected. Use caution and a pair of needle nose pliers to pull it up from the board. The left side of the connector (left as shown in the photo) is easier to grasp than the right, so grab it on that side with the pliers and pull carefully. It will come off.

    • Release the tabs on each side of the RAM chip at the same time. These tabs lock the chip in place and releasing them will cause the chip to "pop" up.

    • Pull the RAM chip out.

    • Repeat this process if a second RAM chip is installed.

    • Remove the seven T8 Torx screws from the lower case.

    • Using your thumbs, slide the lower case toward the front of the computer.

    • The lower case may stick in the front on a tab just above the center of the optical drive. Be careful as you work the case off, or you may break the thin strip of plastic just above the drive.

    • Lift the lower case off.

    • Disconnect the hard drive ribbon from the logic board using a spudger or the tip of your finger.

    • To free the hard drive, remove the two T8 Torx screws from the right wall of the battery housing.

    I suspect you are meant to remove the two T8 Torx screws holding down the drive retaining bar on the other side of the hard drive. Once the bar is removed, the drive will pivot out without having to touch the screws on the battery housing wall side.

    • Remove the hard drive by lifting the left edge up and out of the computer.

    • There are four rubber bumpers that fit over the hard drive screws. Ensure that these bumpers come out when you remove the hard drive.

    The hard drive can be removed with its bumpers intact, by just taking off the black plastic clamp to its right. Reinserting the drive is also vastly easier when done this way.

    • Disconnect and remove the indicated orange ribbon cable.

    • Disconnect the pink and white inverter cable from the inverter board.

    • The display inverter has orange plastic shielding around it that looks similar to the tape used elsewhere within the computer. Do not remove the shielding from the inverter.

    The pink and white inverter cable connection to the inverter board is very tight. Grasp the notch on the right side of the white connector with needle nose pliers and gently wiggle and pull it out of the socket.

    • Remove the two silver T8 Torx screws from the black plastic bar.

    • Lift the black plastic bar out.

    • Reassembly will be significantly easier if you reseat the hard drive before returning the black bar to its place.

    • Disconnect the two orange connectors from the logic board, removing tape as necessary.

    • Remove the drive by lifting the right edge up and out of the computer.

    During reassembly, make sure pink and white inverter cable with white plug does not get trapped under the edge of the drive unit.

    • Disconnect the large DC-In connector from the right side of the logic board.

    • Remove the two T6 Torx screws from the DC-In board.

    • Lift the DC-In board out of the computer by pulling up and away from you.

    • If you don't have a 667 MHz computer, there is a fan in this location which makes it a bit difficult to remove the DC-In board.

    • If there is a fan present, rotate the DC-In board slightly clockwise before easing it out at a slight angle in order to clear the fan clamp on top of it.

    • Before continuing, place a soft cloth on your work surface to rest the computer on. Turn the G4 over and place it on the cloth.

    • Disconnect the four indicated connectors from the logic board.

    • The large multicolor cable may be difficult to free.

    • The top center cable may not need to be disconnected to remove the modem filter board. It connects to the logic board fan to its immediate left, which is attached to the logic board itself.

    Notice the small metal clip in the middle of the optical drive bay - it can be seen on the right side of this picture, just below the keyboard ribbon cable connector. It may come loose when removing the optical drive. Its function doesn't seem to be important (it appears that it just holds couple of conductors) but keep track of it when reassembling the computer.

    If just removing the logic board, I don’t find it necessary to disconnect the top fan connector. It connects to the fan mounted on the logic board , so it doesn’t need to be disconnected when removing the logic board itself.

    • Remove the T8 Torx screw near the heat pipe.

    The Torx screw on the right can be hard to reach (and put back). To get it back, I pushed my Torx wrench through a piece of double sided tape (used for laying carpet), which left a little dot of adhesive on the tip of the wrench that held the screw while performing the contortions to put the screw back in place...

    You're doing something wrong—only the left screw at that position needs to be removed to detach the heatsink from the logic board. In fact this whole walkthru would be simplified a great deal if it concentrated on removing the logic board, heat sink, and internal frame as a unit. There would be only 9 screws instead of ~25, and fewer chances to bend or break intricate parts.

    • Disconnect the two connectors from the modem filter board.

    • To the immediate right of the modem filter board, the heatsink has two sets of five fins with a double-wide space in between them. This space is where the gray & black coiled wire is supposed to go to ensure a flush fit.

    When replacing the logic board, be careful not to lose the top connector's wires under the plate beneath the modem filter board.

    • Remove the modem filter board from the computer by pulling up and to the right.

    • There is a small plastic post which helps hold the modem filter board in place. You need to clear this post to remove the modem filter board from the computer.
