There could be a malfunction of the camera. When something is blocked in the camera, the electronic will shut down, to prevent extra damage. Sometimes the lens is stuck and won't come out. This could have lots of causes, but it could overheat the motor or bring extra damage to the gears. In those cases the batteries can be drained very quick. Sure you checked all contacts of the batteries? They should be clean and shiny. Never use a sharp tool to remove oxide or grease from electronic contacts Only use a dry cloth or special contact oil.
