Hi Stuart, I can reproduce the issue with an up to date Jessie.
1st scenario (not working): I boot the notebook with battery power, I login on KDM and when the KDE desktop is ready I wait till the warning (11%) and critical (10%) thresholds are reached but nothing happens, no messages and no suspend.

I wait till the warning and critical thresholds are reached but nothing happens, no messages and no suspend. 3rd scenario (working): I boot the notebook with AC power. When on KDM I physically remove the battery. Then I login. When the KDE desktop is ready then I insert the battery and disconnect the AC adaptor. I wait till the warning (11%) and critical (10%) thresholds are reached and everything is working as expected. I get a warning message, then I get a critical message and 30 seconds later the notebook is suspending.

I'm really interested to sort this issue out but need some help to get a better understanding how PowerDevil, libsolid4, upower and the kernel are working together. Also some details how to further troubleshoot the issue are very appreciated. Thanks Andreas -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
