Hello PhilMUG. A sad evening for me. My iBook G4 is not starting up. I searched the forum for related threads but majority of the suggestions didn't work. My iBook G4 is having symptoms just like in this thread. I tried these methods: 1. Reset PRAM and NVRAM 2. Reset PMU 3. Removed the RAM 4. Tried to boot from CD (CD won't eject) 5. Tried Target Mode with PowerBook G4 Titanium But all of these with no success. To sum up, these are the iBook's activities: No start-up chime, no display, CD drive spins for around 4 seconds, I can feel the HD's vibration, keyboard has power (caps lock and num lock), battery won't charge - AC adapter lit green. When I press the battery indicator, 4 lights are blinking. I am thinking that the improvised adapter could have fried the Logic Board. I hope not.
