笔记本电脑电池充满电后仍继续放电（不切换到交流电）

笔记本电脑充满电后不会切换到交流电模式。我双重启动，这个问题在 Windows 10 上不存在。但在 Ubuntu 15.10 上它只是不断放电。

Ubuntu 16.04 版本上也仍然存在此问题。

我尝试完全充电（实际上从未发生过，因为 ubuntu 总是显示正在放电，但我将其充电到尽可能高），然后放电至 0 并再次完全充电。但就是不起作用。

这对电池不利，请帮忙。

我尝试过移除 TLP 并使用全新安装，但仍然没有成功，我希望在这种情况下继续使用不会耗尽电池。

答案1

交流适配器显示在线，电池以零速率放电。

电池充电逻辑不受操作系统控制。笔记本电脑中许多独立的微控制器之一控制电池（以及电池本身中相应的微控制器）决定何时以及如何充电。最糟糕的情况是，您的操作系统无法正确解释它们报告的状态，但我不会担心电池被损坏。

PS: 如果你插上了电源做保持充电状态，对吗，它不会放电？
