nd below the display.
MCE strongly recommends that the installation be performed by a
qualified technician. The installation procedure involves disassembling
the PowerBook and exposing its sensitive electronics. This is a delicate
process and, if not performed properly, could cause damage to the
PowerBook. These installation instructions are given for those who
understand these risks. If performed correctly, these instructions will
guide an individual step-by-step through a successful installation of the
new hard drive.
The new hard drive comes formatted and initialized with a Macintosh
driver, but generally requires the installation of appropriate Macintosh
operating system (Mac OS) software for use in the PowerBook. You will
need a reliable Macintosh volume from which to boot the PowerBook in
order to load the necessary operating system software. Once the Power-
Book is booted, the new hard drive will automatically mount onto the
PowerBooks Desktop and is ready for software installation. If the drive
does not mount onto the Desktop, the PowerBook may prompt you to
initialize the hard drive upon startup, after which the drive should then
automatically mount onto your Desktop and be ready for software
installation.
See the PowerBook Users Manual for operating system and other
software installation procedures.
Caution: Due to a bug in Apples ROM support for SCSI Disk
Mode, a PowerBook 3400/G3 which has an internal IDE hard drive

larger than 4GB installed cannot be used in SCSI Disk Mode. One
can use this PowerBook with an internal drive larger than 4GBin
normal Macintosh mode. There is no workaround for reliably us-
ing such a PowerBook in SCSI Disk Mode. It is recommended
that one use an Ethernet connection to transfer files if necessary.
Installation Checklist
In addition to the new hard drive, the following items should also be
found in this PowerBook hard drive upgrade kit:
- (1) Disposable Grounding Wrist Strap
- (1) MCE Standard/Phillips Combo Screwdriver
- (1) Torx T8 Screwdriver
Installation Procedure
Caution: Electro-Static Discharge (ESD) can easily damage
electronic components. Before proceeding, ensure that you are
discharged of static electricity by touching a grounded metal
object and by properly securing the provided Disposable
Grounding Wrist Strap.
Step 1: Place your PowerBook on a hard, flat surface.
Step 2: If your PowerBook is on, turn it off. If the unit appears to be
off, make sure that it is not in Sleep mode.
Step 3: Completely unplug all cables from the PowerBook and remove
any PC Card modules from it.
Step 4: Remove the battery by
pushing the latch button in and
sliding the latch to the side. Pull the
battery completely out of the Power-
Book.

Step 5: To remove the floppy/CD-
ROM drive assembly without
damaging it, turn the unit upside
down as shown. Slide the release
button outward. Grasp the ridged
area of the plastics (not the metal
cover) to prevent bending the
metal top case and possibly
damaging the drive. Grasping the
assembly by its ridged area, pull it
out of the media bay.
Step 6: Close and latch the
PowerBook and turn it upside
down. Remove the 3 screws on
the bottom of the case with the
torx screwdriver.
Caution: If you pull the keyboard too far you will rip the
keyboard cables out of their connectors. Perform the next
steps slowly and carefully.
Step 7: Turn the PowerBook right-side-up, front facing you and lift
open the display. Rotate the
display as far back as it will go
away from you, probably, around
170
° from the base of the Power-
Book. Using the small flat-blade
screwdriver to get underneath it,
lift the keyboard slightly up and
toward you until you feel a small
resistance (its four top interior tabs
should just clear the speaker grill).

Step 8: Gently rotate the top of the keyboard (the end closest to the
display) toward you, laying it face down onto the palm rest.
Step 9: Using the small flat-blade
screwdriver, detach the two
keyboard cables by gently lifting
up their respective connector ears.
Remove the keyboard, and set it
safely aside.
Step 10: If present, grasp the
RAM card by the corners closest to
you (supporting the bottom left
corner over the connector and lift
straight up.
Step 11: Carefully detach the
brightness & speaker cable from its
connector. Remove the screw from
the brightness and speaker grill.
Lift off the grill (the piece under the
up arrow in the picture) until you
feel a slight resistance. STOP!

Step 12: Rotate the top of the grill
toward the front of the PowerBook.
Use your fingers to disconnect the
backup battery connector. (The
backup battery is adhered to the
grill with reusable adhesive. This
does not need to be removed from
the grill.)
Step 13: Grasp the area of the clutch
cover under the display. Using a
fingernail, pull up from the seam in
back and gently rock the clutch
cover until it releases. Pull the
clutch cover straight up, watching
to clear the bottom of the display
assembly.
Note: Familiarize yourself with the palm rest. This
section will have to be rotated into the area originally
occupied by the keyboard. Be carefull not to pull the
trackpad cable out of the connector as you turn over the
palm rest. Perform the next steps carefully.
Step 14: Grasp the right corner of the palm rest and gently but firmly
pull it up. PowerBook 3400 and PowerBook G3 (1997)

Step 15: Referring to the latch noted on the previous diagram, use a
small flat-blade screwdriver to gently press the latch toward the palm rest
and at the same time rotate the top right section of the palm rest towards
the front of the PowerBook.
Step 16: Once the latch is freed, grasp the top right side of the palm rest
and pull it up slowly. Note that there are six more latches connecting the
palm rest, along the front and middle seams. Some of these latches may
be a bit tough to release, especially along the left front seam. You might
try gently rocking the palm rest to free these latches. You might also try
pushing with your thumbs on the bottom half of the case below the front
seam as you pull the top palm rest area with your other fingers.
Step 17: Rotate the palm rest
over until it is laying upside
down in the area that the key-
board originally occupied,
remembering not to pull the
trackpad cable out of the connec-
tor as you turn over the palm rest.
Step 18: Remove the three
interchangeable screws connect-
ing the hard drive bracket to the
CPU stiffener. Lift up the bracket
until you feel a slight resistance -

cable connecting the drive to the

Tip: There are two items that the bracket protects - the hard
drive and the power supply board underneath the right side of the
bracket. When separating the bracket from the computer use a
small flat-blade screwdriver to hold down the power supply
board. Do this by applying slight pressure to the right edge of the
board. Touch only the green part of the IC board.
Step 19: While holding the
power supply board in place
rotate the bracket towards the
front of the PowerBook. Discon-
nect the hard drive cable connec-
tor from the logic board by
carefully pulling up on the
hardened plastic back of the
cable.
Step 20: Remove the four screws holding the drive in the bracket.
Step 21: Remove the hard drive
from within the bracket. Use the pull
tabs to disconnect the cable from the
hard drive.
Step 22: Replace the cable connector onto the new hard drive taking
care to orient it properly for later connection of the other end of the cable
to the logic board.

Caution: Note that the ribbon cable connector does not attach to
the Group B pins in the diagram below. The same is true when
you re-attach the connector to the new drive.
Reverse the relevant previous steps to reassemble the computer.
Replacement Notes
Install the palm rest before the clutch covers. The palm rest tabs fit under
the clutch cover tabs.
When replacing the keyboard screws, you may have to apply pressure to
the keyboard for the screws to engage. Apply pressure with great care.
When reinserting the floppy drive align the bay device carefully. Toler-
ances are tight.
As always, install the PowerBooks battery before connecting the AC
power adapter.
Congratulations! You have completed the hardware installation of your
PowerBook hard drive upgrade.
Note: It is normal for usable hard drive capacities to be reduced
by 5-7% upon initialization of the drive. Also, your drive ships
preformatted and initialized, but does not include system software
on it. If you have the appropriate hardware, such as the MCE Trans-
port PC Card Kit, you may transfer the data from the original
