New Procedures

Flex cable compatibility

The sound and modem flex cables are not interchangeable with the original PowerBook
G4 (17-inch) system. The main logic board will be damaged. The correct flex cables have
the word “POWERBOOK G4 17" 1.33GHZ ONLY.”

No L3 cache

L3 cache is not used on this system. So unlike the previous model, there is no blue
thermal pad on the logic board facing the keyboard.

Thermal module interface

Thermal gel is now used on the ATI Mobility Radeon 9600 graphics chip as well as the
Intrepid chip. The thermal module is different from the previous 17-inch PowerBook. It has
a different interface feature for the graphics chip and now has three heat pipes instead of one.

Important Notes

• If a flex connector has a plastic film located on the top that can be lifted up on one
side, use it to carefully pull up and wiggle the connector from side to side to disconnect
it. Otherwise rock the connector from side to side to disconnect.

• The AirPort Extreme card assembly has a flex cable glued to the card, making it
unique and specific to this computer.

76 - PowerBook G4 (17-inch 1.33GHz) Take Apart

Logic Board

4. Important: To prevent damage to the logic board chips, the thermal material between

the logic board and the heatsink must be softened before removing the logic board.

Use the following procedure:

• Remove all memory cards and leave the memory door off.

• Verify all screws have been removed.

• Verify all cables are disconnected and moved away from the procedure area
shown below.

• Turn on a 1600 watt hair dryer and set it to high. Move the dryer back and forth
continuously, left to right, about one second per cycle, over the area shown below,
holding it about 20 mm (about 1-inch) above the board, for approximately one and
a half minutes. (The temperature should reach approximately 75-80-degrees C
(167-176-degrees F).)

• After at least 45-seconds, and while continuing to move the hair dryer as described
above, insert a black stick just under the left edge of the logic board, where shown
below, and apply slight upward pressure (do not pry). Continue the hair dryer
procedure along with the slight upward pressure on the board until the thermal
material releases and the board moves up easily.

• Once the thermal material has released, discontinue using the hair dryer.

• Continue to the next step before the thermal material cools.

Warning: Do not use a heat gun, or damage can result.

Logic Board

5. Lift the logic board from the left side and pivot along the port side.

Note: The thermal material should easily release. If not, repeat the hair dryer
procedure, above (verify that all the screws have been removed). Apply slow
constant pressure until it releases, avoid over flexing.

Warning: Do NOT flex the board. Give special attention at the narrow neck of
the blower cutout.

6. Carefully coax the port end of the board out of the port openings.

Note: The DVI connector may catch on the part of the frame shown here. Carefully
maneuver it until it releases.

Warning: To avoid flexing the logic board, hold the board vertically along the wide
sides. Do not hold the board by the ends or by the narrow neck at the blower cutout,
or horizontally, as the board’s weight can cause excessive flex.

Replacement Procedure

1. Verify that the replacement logic board has EMI shields attached, as shown. If not,
transfer the shields from the replaced board, or replace with a new shield kit.

2. Use a black stick to remove all the original thermal material on the heatsink at all three
mating surface locations shown below.

3. Vigorously clean remaining residue and adhesive with an alcohol pad.

80 - PowerBook G4 (17-inch 1.33GHz) Take Apart

Logic Board

Warning: Whenever the logic board is separated from the heatsink, you must
remove all existing thermal material and install new thermal material to the heatsink
at the three locations shown above. Failure to do so can cause the computer to
overheat and be damaged.

Important: Avoid unnecessary contact with thermal pads or gel, as dirt and body oils

reduce the thermal pad's conductivity.

If thermal pads have a backing material, remove one side before applying to the heatsink.

Logic Board

Center that side over the mating surface (raised surface) and evenly apply it, without
air pockets, by lightly pressing. Remove any remaining backing. (The picture shown
is for illustration only.)

PowerBook G4 (17-inch 1.33GHz) Take Apart - 81

4. Center and install a new thermal pad onto the heatsink where removed, as shown
below.

Important: If the thermal pad kit includes two same-size pads, apply them, with the
backing removed, one on top of the other as a double layer.

5. Apply approximately 0.3 to 0.5 cubic centimeter (cc) of T630 thermal gel (922-5929) to
the center of the center mating surface on the heatsink.

Note: The 10 cc dispenser may be graduated in milliliters. A milliliter (ml) is the same
as a cubic centimeter (cc).

Note: To apply the thermal gel from the 10 cubic centimeter (cc) dispenser, remove
the end cap and push the plunger until the gel reaches the front opening. Note the
position of the end of the plunger in the tube. Dispense the gel until the plunger end
moves about 1/3 to 1/2 of 1 cc (ml). The plunger will move back slightly when
pressure is released, so push it slightly beyond the amount to be dispensed.

6. On the right mating surface, apply approximately 0.3 cc’s to each of the four outer
corners and approximately 0.5 cc’s to the center, as shown.

82 - PowerBook G4 (17-inch 1.33GHz) Take Apart

Logic Board

Important: With an razor knife, trim any excess thermal pad material, if any, that
extends beyond the mating surface, to prevent it from touching holes in the heatsink.

Note: After installing new thermal material, if you must briefly re-separate the logic board
from the heatsink, it is OK to retain the same, new material, as long as they are not
handled excessively.

Logic Board

PowerBook G4 (17-inch 1.33GHz) Take Apart - 83

7. If the logic board was removed to facilitate another procedure and will be reinstalled,
also remove all the thermal material from each of the three corresponding chips
(shown below) in the same manner.

Important: Use extreme care not to damage the chips or logic board components.

8. To replace the logic board, guide the port side into the port openings on the bottom
case. Align the S-video port first.

Note: Use care not to catch cables under the board as it is lowered into place.

9. Attach the screws in the order shown.

Note: The three screws replaced first have “shoulders” and use wavy washers. Make
sure that the washers do not get caught under the shoulder of the screw when
installing.

10. Reassemble and test all ports, components and functions of the computer.
