New Procedures

If you are familiar with taking apart iBook computers, you will notice some differences with this iBook model:

Slot-load optical drive

AirPort Extreme Card option

Bluetooth option

The number and types of screws differ somewhat from previous models.

Note: The top and bottom EMI shields are now 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 3.5- mm long screw. Use the identifiers as a guide when reassembling the computer.

Tools

The following tools are recommended for the Take Apart procedures:

Coin

ESD wriststrap and mat

Magnetized #0 Phillips screwdriver

Jeweler’s flat-blade screwdriver

Small soft cloth

Torx T8 screwdriver

2.0 mm hex nut driver

Needlenose pliers

Torx T6 screwdriver or 5/32 hex driver (for display housing)

Black stick (or other nonconductive nylon or plastic tool)

Note: To organize the screws you remove from the assembly, use a tray with divided compartments (such as a plastic ice cube tray).
