KDE battery monitor
Dear lazyweb, using a ThinkPad X1 Carbon with Debian unstable and KDE 4.14.2, I have not had battery warnings for a few weeks, now. The battery status can be read out via acpi -V as well as via the KDE widget. Hibernation via systemctl hibernate works as well. What does not work is the warning when my battery is low, or automagic hibernation when shutting the lid or when the battery level is critical.
