I apprecieate that, from memory, even the dual AC loss asks you to press the button just incase it doesn't automatically pop out. I can't remember but dunno on the A320 if it works with the batts off? Seems sensible as they can't rule out that some idiot could have turned them off for some reason. Never flown a boeing, is it not guarded?
