This older digital camera has an internal clock that should keep running when I change batteries. Is there a smaller internal battery to keep the clock alive that may need replacing?

The only alternative to a CMOS battery would be a capacitor serving the same function. https://www.youtube.com/watch?v=o4kEeJx6… is only good for the external screw locations,

The Easyshare C813’s is on the sensor side of the main board. http://guide-images.ifixit.net/igi/SVOdX

Thanks! I’m no stranger to working on such electronics, I’ll give it a go. Who knows, maybe if I’m successful, I’ll write a procedure.
