Configure acpid manually:
First look in /var/log/acpid which event is triggered when the battery
runs low. You'll see a line like
 received event "ibm/hotkey HKEY 00000080 00005001"
where ibm/hotkey HKEY 00000080 00005001 is the name of the event

Then create a file batterylow in /etc/acpi/events that
contains this two lines:
  event=your_event
  action=/usr/sbin/hibernate -F /etc/hibernate/suspend2.conf
replace your_event with the name of the event
