General Information
Overview
Identify the PowerBook G4 (15-inch 1.67/1.5GHz) by noting there is no AirPort Extreme card door in the battery well, as with previous 15-inch aluminum alloy body PowerBooks.
General Information |
PowerBook G4 (15-inch 1.67/1.5GHz) Take Apart - 1 |
Main feature differences from previous models:
•Built-in AirPort Extreme
•Illuminated keyboard on all models
•Built-in fiber optic backlit keyboard—the fiber-optic mat has been replaced with a light panel integrated into the keyboard assembly
•Trackpad and keyboard connect through USB, not directly to the power management system—impacts troubleshooting and resetting the power management unit (PMU)
•1.67GHz (and 1.5GHz) logic boards
•128MB VRAM w/ dual link DVI option on 1.67GHz boards
•Sudden Motion Sensor on logic board—helps protect the internal hard drive should the PowerBook be dropped or experience significant vibration
•80GB 5400 RPM standard, 100GB 5400 RPM hard drive option
•8x SuperDrive (standard on 1.67GHz models)
•Trackpad supports scrolling using two fingers
•Built-in Bluetooth 2.0 + EDR (Enhanced Data Rate)
Some key features common to the two previous models that distinguish these computers from earlier PowerBook models include:
•Aluminum alloy enclosure
•Built-in FireWire 800 port
•Supports USB 2.0
•Uses double-data rate (DDR) memory
New Procedures
Several significant service procedures are different from the two previous 15-inch PowerBooks, including:
•Top case
–New design that is easier to remove and install
–The clips behind the optical drive felt, on previous models, are gone
–Disconnecting the keyboard flex cables requires a different lifting and rotation of the top case, before removing
•Keyboard
–A new design added securing bend-tabs and rigid tabs around the edges of the keyboard that require extra care
•AirPort Extreme card
–The card is no longer replaceable through a door in the battery well—no door
–No AirPort Extreme antenna jumper—the antenna runs continuously from the display to the AirPort Extreme card
•The display panel assembly is not available as a stand alone part. Any service for parts contained within requires disassembly of the display.
•New PMU reset procedure
Other minor differences include cable shapes, routings, connector types, locations, screws, brackets, and part designs.

General Information |
Important Memory Note
Memory from the previous 15-inch (Titanium-series) PowerBooks is not compatible with this computer.
Memory from the PowerBook G4 (15-inch FW800) and PowerBook G4 (1.5/1.33GHz) is compatible (not all memory compatible with the PowerBook G4 (1.5/1.33GHz) will be compatible with the PowerBook G4 (15-inch FW800)).
Service Manual Note
In this manual, graphics or photos are intended to help illustrate procedures or information, only, and may show a different level of disassembly, or show a different configuration or computer model, than your computer.
Kapton® Tape Note
During disassembly, note any Kapton tape use and locations, reapply in the same manner. Do not over apply or build up tape on top of old tape; space tolerances are tight and build up or extraneous use of tape may cause pressure on other components.
Cable Routing Note
During disassembly, note cable routing. Reassemble in the same manner. Verify that cables do not route over components when they should route into lower positions or channels. Verify that the cables are not strained or applying pressure onto other components.

Procedure
Warning: The glue used in this procedure can bond instantly to skin. Do not touch the glue. In the event of contact, review the safety instructions at the end of this document. For additional information, refer to the glue manufacturer:
Elmer's Products, Inc.
Columbus, OH. 43215-3799
www.krazyglue.com
1.Place the computer upside down on a clean, lint-free cloth or other nonabrasive surface.
2.Select a foot from the kit. Verify that the case plug and case foot match (refer to the images shown in the table). Do not use a foot that does not match.
3.Make sure the plug area on the bottom case is clean. If any portion of the soft rubber foot remains, remove it so that only the hard plastic plug is visible.
Important: When positioning the foot, make sure the indents and bumps of the rubber foot match up and fit into the corresponding indents and bumps in the plug. This ensures a balanced and level fitting. (Note: The picture below is of a different foot than on the computer, and is for illustration only.)

4.Warning: GLUE IS AN EYE AND SKIN IRRITANT. BONDS SKIN INSTANTLY. Do not touch the glue at any time. Before opening the glue, review the safety instructions at the end of this document.
Important: The glue tube included in the kit is sealed until first use. Do not break the seal until you are ready to use the glue. To break the seal, hold the tube upright and away from you. Place the hollow nozzle cap on the tube and tighten it all the way down. The tube is then ready to dispense the glue through the nozzle cap.
5.Apply one drop of glue to the plug on the bottom case. Do not spread the glue.
6.Using tweezers or needlenose pliers, carefully position the new foot so its textured surface fits into the inner ring of the plug.
7.Using the end of the tweezers or pliers—not your finger—lightly press and hold the foot in place for 30 seconds.
8.Before turning over the computer, allow the glue to set for at least 15 minutes.
9.Discard the tube of glue.
SAFETY INSTRUCTIONS: GLUE IS AN EYE AND SKIN IRRITANT. BONDS SKIN INSTANTLY. Contains ethyl cyanoacrylate. Avoid contact with skin and eyes. If eye or mouth contact occurs, hold eyelid or mouth open and rinse thoroughly but gently with water only for 15 minutes and GET MEDICAL ATTENTION. Liquid glue will sting eye temporarily. Solidified glue may irritate eye like a grain of sand and should be treated by an eye doctor. If skin bonding occurs, soak in acetone-based nail polish remover or warm soapy water and carefully peel or roll skin apart (do not pull). Contact through clothing may cause skin burn. If spilled on clothing, flush with cold water. Avoid prolonged breathing of vapors. Use with adequate ventilation. KEEP OUT OF REACH OF CHILDREN.

Replacement Procedure
Note: If replacing the top case, remove the keyboard and transfer to the replacement top case.
1.Visually check to verify that all cables are connected and routed correctly with nothing raised up or incorrectly over a component.
2.Check perimeter wiring, where shown, to verify that it will not be caught or pinched by the top case during replacement.
3. Verify that the LVDS cable is secure and lays flat.
Top Case |
PowerBook G4 (15-inch 1.67/1.5GHz) Take Apart - 25 |
4. On the top case, check cable connections and routing.
5.Check that the perimeter metal tabs are not bent.
Note: The metal quickly fatigues and can break off easily. Be extremely careful to gently straighten tabs, if needed.
26 - PowerBook G4 (15-inch 1.67/1.5GHz) Take Apart |
Top Case |
6.Connect the flex cable from the top case to the logic board.
7.Lift the top case slightly and rotate it down over the bottom case (verify that the cable is folding properly) and align the corners.
8.Start at the right corner and guide the top case onto the bottom case. Use a black stick to carefully pull or push tabs slightly, if needed.
Important Notes:
•Some side screws have a flexible screw boss. If they block a tab on the top case from seating, use the pointed end of a black stick through the screw hole to push on the boss slightly.
•The tabs are fragile. Do not apply too much pressure or bend them.
•The top case should lay flat along the sides and top, if not, make sure that cables and components are not interfering.
•Screw order is vital for the proper attachment of the top case.
9.Reinstall the side screws in the order shown, below.
Replacement Note: Do NOT insert side screws into the DVI port screw holes. The screws can jam in the holes, requiring removing the logic board to remove.
