'systemctl hibernate' works but f21 does not hibernate on low battery

I have a new fedora 21 install that will hibernate with 'systemctl hibernate' and correctly restore on subsequent power up but the system will not hibernate on low battery power. The system does display the low battery message and says it will hibernate but continues to run until the battery dies without hibernating. (Note: I added 'resume=/dev/mapper/fedora-swap' to '/boot/grub2/grub.cfg' and '/etc/default/grub' to get restoration to work after 'systemctl hibernate'.)

Running 'gsettings get org.gnome.settings-daemon.plugins.power critical-battery-action' returns 'hibernate'. Is there some other setting required to cause 'systemctl hibernate' to be run on low battery?
