ícone de bateria a 0%;

[herbert jung sin]

Ubuntu!

Estou com o Ubuntu 18.04 em um Dell e7270.

A bateria demora para chegar a 100% quando está perto de ficar cheia. Ela fica por um bom tempo no 98%, falando que falta 0:01 min para encher.

Quando a bateria chega a 100% ela demora cerca de 4.5 horas para chegar a 0%, daí o pc entra em sleep mode.
O que tá me deixando louco é que eu consigo ligar o laptop novamente, e a bateria aguenta mais uma hora inteira com brilho no máximo vendo vídeo no youtube a 2k e som pelos auto-falantes, ainda com o indicador de bateria a 0%!

Vi em uma postagem a respeito de um sensor que poderia estar desregulado. Segui as recomendações de desplugar a bateria, fazer o boot completo somente com o carregador, desligar o laptop, retirar o carregador, reconectar a bateria, reconectar o carregador e fazer o boot novamente. O erro persiste.

Dei um 'purge laptop-mode-tools' e instalei o TLP.

O output do 'tlp-stat' é:
