我在联想 Thinkpad w540 上运行 Ubuntu 17.10。我已经安装了 TLP 并使用了电池充电阈值。我已经安装了 acpi-call-dkms 包来支持充电阈值。但是当我插入充电器时，电池会卡在原来的电量上。它不会再充电了。我附上了有关我的配置的所有相关信息。如果您需要更具体的信息，请告诉我。
这是当没有插入充电器时的情况：

答案1
您的实际阈值设置指示电池控制器在交流电连接且充电水平介于 15% 至 95% 之间时不充电。目前您的电池电量为 59%，因此其工作方式与设计和配置一致。
您可以使用以下方式暂时重置阈值
sudo tlp fullcharge
或者选择更合适的启动阈值，如常问问题 或者通过注释两行配置来完全删除阈值。
