Overview
  Some of the key features that distinguish this computer from earlier notebook models 
include: 
• Faster processor speed: 1.5 GHz (shown on serial number label)
• AirPort Extreme Card installed
• Sudden Motion Sensor (SMS)—Sudden Motion Sensor technology is a bui\
lt-in feature on the logic board that helps protect the hard drive if the computer is \
dropped or 
experiences severe vibration. If the sensor detects motion beyond a pres\
et trigger 
point, it sends a signal to instantly park the drive heads. This action \
helps reduce the 
risk of damage to the hard drive on impact. 
 
Note:   In some environments, such as live concert halls, recording studios, or \
dance clubs, external vibrations may be major enough to cause the sensor\
 to 
trigger unexpectedly, resulting in interrupted sound or video playback. \
Refer 
to the Troubleshooting chapter for instructions on how to disable SMS. 
Note:   In some locations you may see the Sudden Motion Sensor referred to as 
the Mobile Motion Module. Both names refer to the same feature.

• Scrolling Trackpad—A new trackpad feature allows faster navigation in\
 windows with 
scroll bars. To scroll or pan vertically, move two adjoining fingers up \
or down the 
trackpad. To scroll or pan horizontally, move two adjoining fingers left\
 or right on the 
trackpad. You can customize this feature or turn it off in the Keyboard \
& Mouse pane 
of System Preferences. 
 
Note:   If you find that the pointer moves as you type because you accidentally \
brush the trackpad, make sure that the Ignore accidental trackpad input\
 
option in the Keyboard & Mouse pane of System Preferences is selected. F\
or 
more information on using the trackpad, choose Help > Mac Help from the \
menu bar at the top of the screen.

 General Information 
Model Differences
  The external housing of the PowerBook G4 (12-inch 1.5 GHz) model looks the same as on 
the PowerBook G4 (12-inch 1.33 GHz) model. Both have a mini-DVI port (shown below), 
and both have two latches inside the battery bay. 
  
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.
To distinguish the PowerBook G4 (12-inch 1.5 GHz) model from previous models, check 
the processor speed and note the latches in the battery bay.
This computer model includes two latches inside the battery bay. These latches help 
secure the top case to the computer. Refer to the Top Case procedure for more 
information.
