In my case, I have an Olympus C700 digital camera, 2-3 years old with a
power drainage problem.

Unfortunately, that is likely (not certain) to be a failure inside a
custom-made IC. The other thing it could be is a leaky electrolytic
capacitor.

I've bought camera service manuals (for film cameras) from Olympus. Have
you tried calling them?
