I have a PowerBook 100 that powers up but chimes about twice every second indefinitely until power is removed. I’ve replaced all the electrolytic caps and tested in another fully working PowerBook 100 so it’s definitely the logic board. I’ve inspected for any damaged components or corrosion but beyond that I’m stuck. I have the schematic but I don’t understand the POST process to even guess what could cause this symptom.
Could anyone offer any pointers?
Much appreciated.
