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.

• DC-to-DCBoard—Thecomponent 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.
Important: Unless other specific differences are noted, procedures in this chapter apply to both models.
