"No Battery" -- camera dead, no response
Maybe she needs to leave the battery in the camera for a while to charge the capacitor that feeds the camera when changing batteries. It could be that after a long time without battery (and aging) this capacitor gets totally discharged. I know it's a long shot but worth trying.
Looking forward to hear from you
