Does Q have a hidden battery?

Took the battery out of the Q for a recharge. A few hours later put the newly charged battery in the Q. Turned the camera on and was greeted by the set time date menu. Guess There is a 2nd, hidden battery. anyone know for sure?
thanks

Most cameras do have a hidden battery that remember settings when you change your battery. To drain it on a dslr camera, you turn it on with the battery out and hold down the shutter for 30 seconds. I don't know if this would drain the one in the Q, though.

Actually most use a small capacitor, which have life based on number of cycles drained and charged. The best way to ensure
A long life is never leaving your camera without a battery, always switch with a charged one.
Also there was a thread concerning this with the Q that had it happen because of the sd card so try another card and format
It in the camera.

I wondered the same thing with my K-30. It turns out that the camera has what is colloquially known as a "super cap". It's basically a high capacity capacitor which can can be charged quickly and drained slowly. Remembering the settings, date, time, etc takes very little power. The internal processors slow way down into near sleep mode states. It would take many, many days to discharge this super cap down to nothing.
