Under the keyboard

1. If the computer is on, shut it down and leave the lid open.
2. Remove the computer's keyboard. For more information on how to do this, see technical document 111917, "Keyboard Replacement Instructions".
3. The serial number and Ethernet ID (also called a MAC address) are located underneath the keyboard on the upper ledge. The Ethernet ID is located on the left side of the ledge, and the serial number is to the right.

In the battery bay

1. If the computer is on, shut it down and close the lid.
2. Turn the computer over so you are looking at the battery door.
3. Remove the battery door. For more information on how to do this, see technical document 88121, "Replacing the Battery".
4. The serial number is located on the bottom of the bay for any white iBook EXCEPT the iBook G4 (Late 2004) and most iBook G4 (Mid 2005) models.
