Customer spilled water on this Mac Powerbook G4 laptop. It was not turning on at all. We performed a full internal cleanup but still it would not turn on after assembling it back. In this particular Mac model the power button and keyboard are part of palmrest and they have a tendency to fail as well. We tried our own palmrest and managed to start the laptop. After fully testing the machine we ordered the palmrest and replaced it. Another Mac brought back to life!
