General Information
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 built-in feature
General Information
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 preset 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.
In some environments, such as live concert halls, recording studios, or
Note:
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. For
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.

Procedure
Warning: The glue used in this procedure can bond instantly to skin. Do not touch the
glue. In the event of contact, review the safety instructions at the end of this document. For
additional information, refer to the glue manufacturer:
Elmer's Products, Inc.
Columbus, OH. 43215-3799

1. Place the computer upside down on a clean, lint-free cloth or other nonabrasive
surface.
2. Select a foot from the kit that matches the plug on the bottom case. (Refer to the
images shown in the table.) Do not use a foot that does not match.
3. Make sure the plug area on the bottom case is clean. If any portion of the soft rubber
foot remains, remove it so that only the hard plastic plug is visible (as shown below).
Battery Plug Case Plug
Important: Notice the inner ring of the plug. When positioning the foot, make sure
the textured plane of the rubber foot fits into the compatible ring in the plug. This
ensures a balanced and level fitting.

4. Warning: GLUE IS AN EYE AND SKIN IRRITANT. BONDS SKIN INSTANTLY. Do not
touch the glue at any time. Before opening the glue, review the safety instructions at
the end of this document.
Important: The glue tube included in the kit is sealed until first use. Do not break the
seal until you are ready to use the glue. To break the seal, hold the tube upright and
away from you. Place the hollow nozzle cap on the tube and tighten it all the way
down. The tube is then ready to dispense the glue through the nozzle cap.
5. Apply one drop of glue to the plug on the bottom case. Do not spread the glue.
6. Using tweezers or needlenose pliers, carefully position the new foot so its textured
surface fits into the inner ring of the plug.
7. Using the end of the tweezers or pliers—not your finger—lightly press and hold the
foot in place for 30 seconds.
8. Before turning over the computer, allow the glue to set for at least 15 minutes.
9. Discard the tube of glue.
SAFETY INSTRUCTIONS: GLUE IS AN EYE AND SKIN IRRITANT. BONDS SKIN
INSTANTLY. Contains ethyl cyanoacrylate. Avoid contact with skin and eyes. If eye or
mouth contact occurs, hold eyelid or mouth open and rinse thoroughly but gently with
water only for 15 minutes and GET MEDICAL ATTENTION. Liquid glue will sting eye
temporarily. Solidified glue may irritate eye like a grain of sand and should be treated by an
eye doctor. If skin bonding occurs, soak in acetone-based nail polish remover or warm
soapy water and carefully peel or roll skin apart (do not pull). Contact through clothing may
cause skin burn. If spilled on clothing, flush with cold water. Avoid prolonged breathing of
vapors. Use with adequate ventilation. KEEP OUT OF REACH OF CHILDREN.
