Hallo zusammen,
ich habe mir vor kurzem Ubuntu im Dualboot mit Windows 8.1 auf mein X240 installiert.
Hardwaremäßig funktioniert alles ganz gut das einzige was mich stört ist die Akkulaufzeit unter Ubuntu,
die ist im Vergleich zu Windows nämlich katastrophal obwohl ich schon TLP nutze.
Ich habe mal einen wagen "Vergleich" gemacht, und zwar ein Video mit VLC unter Windows und Ubuntu so lange laufen lassen bis der Akku leer war.
Bluetooth war beide mal aus, Wlan an und angepasste Helligkeit (ca. 25%).
Unter Ubuntu bin ich auf knapp 03:20 Stunden gekommen und unter Windows auf 7:20 also ca. 4 Stunden mehr. :cursing:
Meine TLP-Config sieht wie folgt aus:
Was mir auch aufgefallen ist, das Lüfter unter Ubuntu öfter an ging wobei er unter Windows die ganze Zeit komplett aus war,
obwohl ich bei Windows und Ubuntu die gleichen Temperaturschwellen für die erste Lüfterstufe gesetzt habe (65°C).
Kann man noch irgendwie was machen um den Akkuverbrauch verbessern oder ist hier das Ende der Fahnenstange erreicht
und Ubuntu geht nicht einfach nicht so effizient mit den Komponenten um?
Wahrscheinlich wurde solche Fragen schon öfter gestellt aber ich hoffe ich könnt mir trotzdem helfen.
Gruß,
Daniel
