Repairing an iBook's retro internal circuits

In the era of MacBooks, MacBook Pro's and MacBook Air's, an iBook looks like a dinosaur. However, if it still works, that machine will still be usefull for some purposes.
Reboutte, a member of our fora, dediced to repair a broken iBook - apparently a wire had come loose, and made a short circuit.

He managed to fix the problem, and posted photos (with explanation) of the process online:
