Important:
model is the appearance of the foot sockets. Check the foot sockets on the bottom case to
see this difference. For this model, the foot sockets are uniformly flat with no "dimples."
However, the foot sockets are compatible with earlier models, so this physical difference is
not an absolute indicator of the model type. Be sure to confirm the model type using serial
number verification.
The only noticeable physical difference between this model and the earlier G4
iBook G4 (Early 2004): Foot sockets include three "dimples"
iBook G4 (Late 2004 and Mid 2005): Foot sockets are uniformly flat

• The procedures for the RAM shield, cables, hard drive, reed switch, and heatsink differ
somewhat from earlier models.
• The number and types of screws differ somewhat from previous models.
Note:
The top and bottom EMI shields are marked with screw identifiers for most of the
screw locations. The screw identifiers are in the form of "M2x_" where the last digit
indicates the approximate screw length. For example, a marking of "M2x3" indicates a 3.5mm long screw. Use the identifiers as a guide when reassembling the computer.

Replacing the Feet and Sockets
1. Install the new socket. For the best fit, do not reuse the old socket.
Replacement Note: When replacing the socket, notice the wedge area on the
bottom of the socket and the matching wedge area in the bottom case. Position the
socket in the bottom case to align the wedge areas. You might need to rotate the
socket slightly until it sits flat into the bottom case.
With the socket sitting flat in the bottom case, install the screw.

3. Before installing the replacement foot, check the shape. The socket and foot are
keyed:
• The socket has three identical openings and a fourth indented area.
• The foot has three identical raised areas and a fourth smaller raised surface.
