On a Dell Inspiron 8000. System will not go into Suspend to Disk (Hibernate) when low battery. in /etc/sysconfig/apm-scripts/apmscript under the "change battery section" there is a suggestion to do apm -s but that does not work. There should be a hook to see when a battery reaches a certain percentage for example 5% and then it will triggers suspend to disk.
Shouldn't the BIOS taking care of entering hibernation mode when it's running extremely low on power? No problems here on a Gericom 3xC.
