I left my M-50 without batteries for a day or less. When returning it to service with a fully charged battery, my info settings had disappeared. Is there a hidden small battery somewhere in the camera? I have a much older Canon camera that has a button battery in an external compartment that is easy to get to. Is there a hidden battery and if so, where is it and can it be user replaced? Thanks for any and all information.

Has operation (battery memory retention) restored to normal for you?  If not, then your little on-board button cell Lithium rechargeable might have died (perhaps prematurely).  Panasonic (the primary manuf of these Li-Manganese Silicon batts) lists the nominal recharge cycles at 100, so keep your (big) primary battery inserted as much as possible.  I never leave mine out actually (I always make sure it’s charged).
