Model Differences
The external housing of the PowerBook G4 (12-inch 1.33 GHz) model looks the same as the PowerBook G4 (12-inch DVI) model. Both have a mini-DVI port (shown below).
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 1.33 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
www.krazyglue.com
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).

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.
