My iBook G4 was having trouble charging and after trying different cables, it seemed the problem was the DC-in board. Our local Mac repair shop quoted us $170 for the repair.
The items arrived faster than promised and the instructions were easy to follow. Saved $140 from what the repair shop would have charged for a job that maybe took me 15 minutes to complete. The hardest part is getting the plastic cover off the back.
Did not need the spudger as suggested but you will need a very small phillips head screwdriver for the interior screws.
