Random Kodak Retro Digital Cameras C633, CX7330, C643, Z760, C743, C530 (hi-2-u)

There is a strange issue with at least (3) of them. Even with AA batteries they would not turn on, until I plugged in a 3V AC Adapter. After I turned it on using an AC adapter I could then unplug and it would turn on normally with AA batteries only.
