Install Software
Before proceeding with the hardware installation, you must run the Crescendo/PB
Installer.
1. Insert the Crescendo diskette into the floppy disk drive or the Sonnet
Installer CD into the CD-ROM drive. Double click the Crescendo/Encore
Install icon.
2. By default, with “Easy Install” selected from the pop-up menu, the required
software will be installed into the active System Folder on the boot drive. If
this is ok, click the Install button; otherwise, select “Custom Install” from the
pop-up menu for more options or select another drive to install the software.
The installer will install the appropriate software into the System Folder of
your computer. If the installation was successful, a dialog box will appear.
3. Click Quit to leave the installer and shut down your computer.
Shut Down and Open Computer
1. If you have not already done so, shut down your PowerBook. If it has been
on for any length of time, wait a few minutes for it to cool before beginning
the installation.
2. Disconnect the power adapter and any peripheral cables from the back of
the PowerBook and move it to an area where you can freely work.
3. If installed, remove the battery from the computer.
4. With the front of the PowerBook facing you, find the speaker grill located
above the keyboard. Remove the speaker grill by sliding it to the left and
away from the computer (Figure 1). You may need to use some gentle
pressure to move it sideways if it has never been removed before. Set the
speaker grill aside.
5. Place your finger (or carefully slide the end of the Phillips screwdriver) under
the top edge of the keyboard and lift it up. Rotate the keyboard forward
(Figure 2) so that it rests upside down on the lower part of the computer’s
case. Take care not to disconnect the keyboard cable from the logic board.
Remove Metal Heat Shield
1. Locate the metal heat shield (Figure 3) and touch it to discharge any
potential damaging static electricity.
Quick Start Guide for Crescendo/PB
Support Note: When handling computer products, take care to prevent
components from being damaged by static electricity; avoid working in
carpeted areas. Handle electronic components only by their edges and avoid
touching connector traces and component pins.
WARNING: To avoid damaging your PowerBook, you should not
install any type of expansion card while a power source is connected.
Follow the instructions below for details on when to disconnect the power
adapter and remove the battery.

Support Note: To avoid regenerating a static charge in your body, do
not walk around the room until after you finish the installation, reassem-
ble and close the computer.

2. Use the Phillips screwdriver to loosen the six screws that hold the heat
shield in place (Figure 4). Remove the screws, noting the two screws that
secure the rear of the heat shield are longer than the other four screws.
Set the screws aside.
3. Lift the heat shield up and away from the computer (Figure 5) and set it
aside near the screws you just removed.
Remove Processor Card
1. Locate the processor card (Figure 6). It is in front of the keyboard cable
connected to the logic board. The processor card should also have four
stand-offs that secure it in place.
2. If present, remove the screen cable shield. Use the hex head driver tool to
loosen the stand-offs (Figure 6). Remove the stand-offs and set them aside,
noting the two rear stand-offs that run horizontal to the screen are longer
than the two stand-offs in front of the keyboard cable.

3. Carefully unseat the processor upgrade card by first lifting up the edge near-
est the keyboard, then lift up the edge nearest the screen. Once un-mated
from the logic board connectors, lift the processor card out toward the key-
board while holding the front edge higher than the screen edge (Figure 7).
Set the card aside near the stand-offs you just removed.
Install the Crescendo/PB
1. Remove the Crescendo card from the anti-static package, making sure to
handle the card by the edges.
2. Lower the card into the unit while holding it with the screen edge lower
than the keyboard edge. Align the screen end of the card connectors with
the logic board connectors. Once aligned, gently press on the outer edges of
the board (as indicated in Figure 8) until the card’s connectors begin to
engage the main logic board connectors. Take care not to press on the board
component shown in Figure 8. Then in one motion, lower the front edge of
the card and firmly press down until the card is seated. DO NOT FORCE IT!
The connection may be tight, but should not require excessive force during
insertion. If the card does not join properly with the logic board connectors,
carefully remove the card using the procedure above, check for bent pins,
and reinstall it using the procedure outlined above.
3. Package the old processor card into the Crescendo’s anti-static package and
store it in a safe place.
4. Reinstall the four stand-offs into their respective holes in the four corners of
the Crescendo card. The two long stand-offs run horizontal to the screen; the
two short stand-offs run horizontal to the keyboard. Reinstall the screen
cable shield if present.
Reinstall Metal Heat Shield
Reinstall the heat shield. Slide the front edge of the heat shield under the case,
then lower the back of the shield until it is flush with the logic board (Figure 9).
Reinstall the six screws. Make sure to put the two long screws at the rear corners
of the shield.

Reassemble Computer
1. Reinstall the keyboard (Figure 10). Gently lift it up and rotate it back into
place, lowering the top edge of the keyboard into the upper part of the case.
2. Reinstall the speaker grill (Figure 11). Lower the grill into the opening above
the top row of keys. Slide the grill to the right to lock it in place.
3. Affix the Powered by Sonnet label to the front of your computer.
Reset Power Management
Hold down the On/Off key for 30 seconds. This procedure acts as a reset for the
PowerBook’s power management chip and ensures that a new processor upgrade
card is recognized at the next startup. Clicking sounds from the speaker may be
audible during this procedure. This is normal and does not indicate a problem
with the installation.
Turn On Computer
1. Before reinstalling the battery or any peripheral cables, reconnect the A/C
power adapter and turn on your upgraded G3 PowerBook. You should hear
the startup tone and see the Crescendo extension load during startup. The
Crescendo extension will rebuild your desktop the first time you restart the
computer. If the PowerBook fails to boot, refer to the troubleshooting section
of these installation instructions.
2. Once the PowerBook has booted, shut down the unit and reinstall the
battery and any peripheral cables.

Troubleshooting
This section addresses issues encountered by some Crescendo/PB users.
Problem:
Although the A/C power adapter has been reconnected, there is no startup
tone when the PowerBook is turned on.
Solution:
Does the sleep light on the upper right corner of the screen stay on
(green)?
Yes: a) The PowerBook power management circuit needs to be completely
reset. To do this, disconnect all peripherals and power sources (bat-
tery and A/C power adapter) from the PowerBook. Use a small
piece of tape to hold down the On/Off key, then leave the
PowerBook in this configuration overnight (8-10 hours). It is nor-
mal if clicking sounds from the speaker are audible during this
procedure. Repeat step 1 of the “Turn On Computer” section of the
installation procedure.
No: a) The PowerBook power management circuit may need to be reset
longer than the 30 seconds prescribed in the “Reset Power
Management” section of the installation procedure. Disconnect all
peripherals and power sources (battery and A/C power adapter).
Hold the On/Off key down for several minutes. It is normal if click-
ing sounds from the speaker are audible during this procedure.
Repeat step 1 of the “Turn On Computer” section of the installa-
tion procedure.
b) The Crescendo card may not be installed properly. After attempting
the above extended reset procedure, verify the Crescendo card is
installed properly.
