PowerBook G3 Series: Identifying PowerBook G3 Series Circuit Boards
Discussion: When replacing PowerBook G3 Series circuit boards it is very important to check the ID codes to verify that you are ordering the correct part.
The ID codes listed below can be found within the serial numbers that are attached to the circuit boards. They are not part of the whole unit serial number that is attached to the bottom of the PowerBook.
These serial numbers can be located in the following locations.
• Microprocessor Board: Follow the instructions in Service Source for removing the microprocessor card. With the card removed, look at the serial number/bar code label on the SODIMM conector on the bottom side of the card.
Hot Issues Overview - 3
• I/O Logic Board: This serial number label is viewable from the opening for the PC Card slots. You don’t need to disassemble the PowerBook. Gently push in the PC Card slot doors and look inside the opening. You should see the serial number/bar code label. You may need to use a small flashlight to see the lettering on the label.
The ID codes are printed in one of two ways:
– Either the next-to-last three characters in the serial number. For example, if the serial number is *CK8xxxxxyyyx* then the ID code would be “yyy”.
– Or within the last 5 characters of the serial number. For example, if the serial number is *KC8xxxxxxyyyxx* then the ID code would be “yyy”. This type of serial number label has Singapore printed directly after the serial number.

Hot Issues Intermittent Video with 13.3” Display - 6
Intermittent Video with 13.3” Display
Customers may describe symptoms related to intermittent video when using PowerBook G3 Series computers configured with the 13.3* display. Reported symptoms may include one of the following:
• intermittent vertical lines
• flickering of the video
• the screen may fade to white.
These symptoms may be caused by an intermittent connection between the internal display cable and the connector it attaches to on the display. If the customer experiences one of these symptoms the unit should be dispatched for replacement of the display cable. Replacement of the I/O logic board or the display are not necessary.

System Configurations
At introduction in May, 1998, six basic configurations of the PowerBook G3 Series computer were available. With build-to-order options, customers may customize their PowerBook G3 Series computers in a variety of ways.
In September, 1998, five new configurations were introduced that feature three new processor cards and support resolution switching of the display. An additional configuration was added October 1. To determine whether the unit you are looking at is one of these later configurations, check the Apple System Profiler to see if the unit has a clock speed of 233 MHz with 512K cache, 266 MHz, or 300 MHz.
For more details on these configurations and on the build- to-order-options, see the Data Sheet at the end of the Specifications chapter of this manual.

DVD-Video PC Card Option
The DVD-Video PC card is an option that was introduced in July, 1998 for the PowerBook G3 Series. Together with its software, the DVD-Video PC card provides DVD-Video playback capabilities for PowerBook G3 Series computers equipped with a DVD-ROM expansion bay module.
DVD discs are similar to music CDs and CD-ROM

discs, but they can hold up to 25 times the amount of data. This greater capacity allows an entire movie to be stored on a single disc, usually with extra storage space left over. Some DVD-Video discs use the additional storage space for different language tracks, extra video clips, and director’s notes.
Important: Audio and video quality varies extensively among DVD-Video disc titles. Symptoms that suggest a DVDVideo PC card failure could actually be caused by a damaged or poorly manufactured DVD-Video disc. To avoid needless DVD-Video PC card replacement, we suggest testing at least two DVD-Video disc titles to see if the symptom persists. For troubleshooting procedures, refer to “DVD-Video PC Card” in the Troubleshooting chapter.
For DVD specifications refer to the DVD data sheet that follows the Specifications chapter in this manual.

Repair Strategy
In the US only, refer to the latest program notice for special service considerations. Beginning September 1, 1998, parts for the PowerBook G3 Series will be available for order through the Service Price Pages and the AppleOrder and ARIS systems. Except for the displays, Apple Authorized Service Providers in the US can now repair PowerBook G3 Series systems. In Canada, Apple Authorized Service Providers can also repair displays.
Because of the complexity of the repairs, we are limiting all PowerBook G3 Series display repairs, except for repairing the latch, to the Central Product Repair Center (CPRC). This includes the 12.1" STN display. On PowerBook G3 Series 12.1” STN displays, the EMI shield is prone to tearing and may not fit correctly after reassembly (refer to the Additional Procedures chapter for more information).

Repair Issues
Prevent Cosmetic Damage
The outside plastics of the PowerBook G3 Series computers are vulnerable to scratches and finger marks from skin oil. To prevent cosmetic damage to a customer’s PowerBook, do not wear jewelry when handling the computer, and wear gloves if you have them available. Wipe fingerprints from the outside plastics with a damp cloth.
Install Microprocessor Board Securely
The microprocessor board can be partially inserted and the computer will still function. However, over time, heat will cause the microprocessor board to lose contact and can cause the system to have intermittent problems such as no booting.
Basics |
Repair Issues - 17 |
|
|
|
|
|
Therefore, verify proper installation by pressing on the |
|
|
microprocessor board connector a second time to make sure |
|
|
the board is fully seated. |
|
Verify Parts Before Placing Orders
The PowerBook G3 Series computers offer build-to-order features. For this reason, it is mandatory that you either see the part you are replacing, or use diagnostics to identify the part, before you place a parts order. Misidentification of parts may occur if this step is not performed first.
