筆記型電腦電池即使充滿電後仍繼續放電（未切換到交流電）

筆記型電腦充滿電後不會切換到交流模式。我使用雙重引導，這個問題在 Windows 10 上不存在。

Ubuntu 16.04 變體上也存在問題。

我嘗試完全充電（實際上從未發生過，因為ubuntu總是顯示放電，但我將其充電到盡可能高），然後放電至0並再次完全充電。但它就是行不通。

這對電池不好，請幫忙。

我已嘗試刪除 TLP 並使用全新安裝，但仍然沒有運氣，我希望在這種情況下繼續使用不會耗盡電池電量。

交流電源轉接器顯示在線，電池正在以零速率放電。

電池充電邏輯不受作業系統控制。筆記型電腦中的眾多獨立微控制器之一控制電池（以及電池本身中的相應微控制器），決定何時以及如何充電。在最壞的情況下，您的作業系統將無法正確解釋它們報告的狀態，但我不擔心電池被損壞。

PS：如果你已經插上電源了做保持充電狀態，對吧，不放電？
