Comment 26 for bug 481576

Im running Lucid Lynx (i386) on a Acer Aspire One D150, (upgraded to 2gb RAM) i can confirm that hibernate function works for me if I have the value percentage_action on 5 or higher, then the system hibernates automatically.

I also tried lower values than 5 and then nothing happened until battery totally died.

In my case it seems that my battery needs to have at least 5% (actually 4%, because the action starts when its not 5% anymore) to be able to complete the hibernate. Because when computer then is turned off i cannot start it again without the AC connected. Also tested to just connect AC during startup, then unplug, when I did that the computer died immediately. Conclusion: the battery really is empty.

Therefore in my case this isn't a bug it,s just needs the correct action value. Maybe its the same for some of you others.

Just a hint to try. Good luck
