PowerBook G4 (17-inch DLSD/1.67/1.5/1.33GHz) Basics - 1 |
From the exterior, the PowerBook G4 (17-inch Double-Layer SD) physically is identical to its predecessor, the PowerBook G4 (17-inch 1.67GHz).
The quickest ways to identify the PowerBook G4 (17-inch Double-Layer SD) computer:
•If the system is bootable, power it on. After pressing the power button the sleep LED light comes on solid and stays on until video appears onscreen.
•Also the "About this Mac." Under Memory, shows DDR2 memory.
• Check a memory card to see if it is DDR2 (keyed differently than DDR)
2 - PowerBook G4 (17-inch DLSD/1.67/1.5/1.33GHz) Basics |
General Information |
Main feature differences from the previous models:
•Higher resolution 17-inch display, 1680 x 1050, 116 dpi (previously 1440 x 900, 100 dpi)
–Prism technology is used to increase the screen brightness from 150 nits to 220 nits
•Support DDR2 memory up to 2GB
•Double-Layer SuperDrive allows user to burn two layers through a single side of a double-layer burnable disk.
•120GB 5400 RPM standard, 100GB 7200 RPM hard drive option
New Parts and Procedures
Service parts and procedures are different from the previous 17-inch PowerBook computer including:
•Top Case
–As the sleep magnet has been relocated to the display bezel, the sleep sensor has moved from the trackpad flex to the edge of the top case. Previous top cases will not work with this system.
•Keyboard
–The keyboard has a narrower flex than the previous the integrated backlight keyboard used in the PowerBook G4 (17-inch 1.67GHz). These two keyboards are not interchangeable. This keyboard is the same as the PowerBook G4 (15-inch Double-Layer SD).
•Mass Storage (Hard drive and optical drive)
–Both devices share a single ATA bus using a cable select addressing scheme. Previously each drive was a master device on separate ATA busses. Although, an older hard drive may work in this system, the optical drive will either not show up as a device or cause the system to not boot-up properly.
•AirPort Extreme and Bluetooth 2.0
–These two functions have been combined on a single card.
–The card has the antenna diversity function built-in, eliminating that card in the clutch barrel.
•Main Logic Board
–A new thermal grease is used. It has a greyish color.

Flex cable compatibility
Warning: The logic board will be damaged if the wrong sound board or modem flex cable is used. The sound cable marked PowerBook 17" 1.33GHz or greater can NOT be used on the PowerBook G4 (17-inch 1.67GHz) computer. Cables from the earlier PowerBook G4 (17-inch) system are also NOT compatible.
The cables must be marked as indicated in the following chart:

Important Notes
•To disconnect a flex cable connector, if the connector has a plastic film on its top that can be lifted up on one side as a pull tab, carefully pull it and wiggle the connector from side to side to disconnect it. Otherwise carefully rock the connector from side to side, or use a black stick to carefully pry up the connector.
•The AirPort Extreme card assembly has a flex cable glued to the card.

Zero Insertion Force Connectors
Zero insertion force (ZIF) connectors are used in several locations in the computer.
Important: The locking bar on the ZIF connector is extremely fragile and is not intended to separate from the connector. When releasing a bar, use extreme care and a restrained light pressure to move the bar only slightly.
Warning: If a locking bar breaks, you will need to replace the board.
To release the flex cable
Use a flat-blade tool to move the bar on both sides.
6 - PowerBook G4 (17-inch DLSD/1.67/1.5/1.33GHz) Basics |
General Information |
To connect a flex cable
Make sure the locking bar is released, then slide the end of the flex cable all the way into the connector. Hold the cable in place, then slide the locking bar into the connector on both sides to secure.
Important: Verify that the cable is straight. Use either the alignment mark, if present, or the metal edge on the cable as a guide to ensure the cable is straight.
Warning: If the flex cable is inserted crooked, some signals may not be connected or signals may short together (a bad connection is shown below.)
Note: If a cable is not securing properly, verify that it is inserted on the correct side of the locking bar.

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 section. 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.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 (as shown with both types of plugs below).
Important: Notice the recessed hole in the center of the plug. When positioning the foot, make sure the raised bump on the textured plane of the rubber foot fits into the center hole in the plug. This ensures a balanced and level fitting.

3.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 section.
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.
4.Apply one drop of glue to the plug on the bottom case. Do not spread the glue.
5.Using tweezers or needlenose pliers, carefully position the new foot so it is centered over the plug, and its integral bumps fit into the compatible holes in the plug.
6.Using the end of the tweezers or pliers—not your finger—lightly press and hold the foot in place for 30 seconds.
7.Before turning over the computer, allow the glue to set for at least 15 minutes.
8.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.
