I've posted this before, but it was sort of buried within another message. It was suggested I might expose this data as a separate message, so folks only have a single item to think about! <g>
When I first got my S4, while uploading the it's images to the computer, I used to leave the battery in, attaching the camera to the mains via Pentax' converter, plugging in the signal lead, turning on the camera and uploading. No matter how long it took, sometimes as short as 15 minutes, after I worked my way out, turned the camera off, unplugged, then turned the camera back on again, it told me my batteries were depleted! In 15 minutes?
Anyhow, as an experiment, the last few times I took the battery out of the camera _before_ I attached it to the CPU. Now, after unplugging, I replace the battery, turn the camera back on and voila! no more problems with "battery depleted."
I don't recall seeing a warning to NOT leave the camera's battery in while powering up with the converter, but for some reason, MY camera doesn't like it!
I don't know if it _really_ depletes the camera's battery in as little as 15 minutes, or that leaving the battery in messes up the camera's way of keeping track of battery level, but in either case there's no problem any more. I'd think there would be some caution about that in the manual... Maybe I just missed it. Fortunately, it doesn't seem to have harmed the battery in any way.
As always, comments welcome...
