PowerBook G3 Series: Identifying PowerBook
G3 Series Circuit Boards
Discussion:
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.

• 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.

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.

the unit to be dispatched to Apple’s Central Product Repair
Center. If customers wish, they may contact Apple to
arrange this dispatch themselves.

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 buildto-order-options, see the Data Sheet at the end of the
Specifications chapter of this manual.

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
BasicsDVD-Video PC Card Option - 10
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.

operation and installation
manual.
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.
BasicsRepair Strategy - 11
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).
BasicsRepair Strategy - 12
Service the PowerBook G3 Series computers through module
exchange and parts replacement. Customers can request onsite service from an Apple Authorized Service Provider Plus
(AASP+), Apple Assurance (US only), or Apple Canada
Technical Answerline (Canada only). They can also choose
carry-in service from an AASP.
Ordering
Apple Service Providers planning to support the computer
systems covered in this manual may purchase Service
modules and parts to develop servicing capability. To order
parts, use the AppleOrder (US only) or ARIS (Canada only)
system and refer to the PowerBook G3 Series “Service
Price Pages.”
Large businesses, universities, and K-12 accounts must
provide a purchase order on all transactions, including

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.
BasicsRepair 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.

I/O Logic Board Identification
There are two I/O logic boards with both TV out and 4 MB of
SGRAM. Look for these differences to differentiate them:
• 661-2019 has components at locations U8 and U9 on the
top of the board under the microprocessor board, and an
ATI Rage LT chip on the bottom of the board.
• 661-2087 has no components at locations U8 and U9 on
the top of the board under the microprocessor board, and
has an ATI Rage Pro chip on the bottom of the board.
