How to replace the track pad once the track pad panel has been removed.

Your track pad is one of the most important parts of your PowerBook's user interface. If the track pad is damaged you will need to use an external mouse or replace the track pad. This is one of the hardest parts to get to in the computer. Before attempting, make sure you will be able to keep the removed parts organized to aid in reassembly.
