Ich wäre für Tipps jeder Art zu haben wie sich die Akkulaufzeit bzw. der Energieverbrauch meines X301 unter Ubuntu 14.04 optimieren ließe.
Der 6-Zeller hat noch gut 35Wh Kapazität, diese bringen mich aber bestenfalls 3 Stunden weit. Als ich letztens eine längere Präsentation in Form eines simplen PDF gehalten habe war nach 2,5 Stunden der Akku runter auf 11%.
TLP ist drauf, tlp stat liefert folgende Ausgabe:
