L'icône de la batterie ne s'affiche pas dans Ubuntu 18.04

Je viens d'installer Ubuntu 18.04 avec Windows sur mon ordinateur portable de jeu Dell Inspiron 7000. Mon problème est que l'icône de la batterie ne s'affiche pas. Lorsque vous utilisez la commande upower -i /org/freedesktop/uPower/devices/battery/BAT0 sur le terminal, no power supply apparaît.

Pourquoi est-ce?

Assurez-vous que vous exécutez le paramètre correct. Par exemple, en utilisant vos paramètres sur mon système:

$ upower -i /org/freedesktop/uPower/devices/battery/BAT0
  native-path:          (null)
  power supply:         no

En utilisant le paramètre correct cependant:
