PowerBook G4 (12-inch) Take Apart
General Information
Model Differences
The external housing of the PowerBook G4 (12-inch DVI) model looks the same as the
PowerBook G4 (12-inch) model except for one port. To distinguish the models, look for a
mini-DVI port (shown below) on the PowerBook G4 (12-inch DVI) computer.
PowerBook G4 (12-inch DVI)
The mini-DVI port is used with an adapter cable to connect the computer to a monitor,
television, VCR, or other video device. The adapter cables that can be used with this port
include a mini-DVI-to-DVI adapter, a mini-DVI-to-VGA adapter, and a mini-DVI-to-S-Video
adapter.
By contrast, the PowerBook G4 (12-inch) computer has a video-out VGA port instead of a
mini-DVI port.

Specific model differences that are noted in the Take Apart procedures include
• Reed Switch Board and Cable—For the
PowerBook G4 (12-inch DVI) model, this
part is called the "Hall Effect Sensor Board and Cable," but the procedure is
the same.
• DC-to-DC Board—The
component layout on the board differs, but the procedure
is the same.
• Heatsink—The heatsink shape and thermal pad placement differs.
• Inner Frame—The main frame shape differs, but the procedure is similar.
• RJ11 Modem Board—The procedure is the same, but the placement of the tape that
secures the cable differs.
• Fan—The fan is secured to the heatsink in the
PowerBook G4 (12-inch) model,
but it is secured to the inner frame in the PowerBook G4 (12-inch DVI)
model.
• Logic Board—The component layout on the board differs, but the procedure is the
same.
• Optical Drive—The slot load bezel must be transferred to a replacement optical drive
for the
PowerBook G4 (12-inch) model only.

Unless other specific differences are noted, procedures in this chapter apply
to both models.
