联想 ThinkPad X270,Ubuntu 20.04,一切正常。
然后我安装了 22.04。
现在(在适配器上)顶部面板指示器显示电池电量约为 70%,未充电。在电源设置中:内置电池电量为 30%,适配器开启,未充电。可更换电池电量为 99%,适配器开启,未充电。
当我拔下笔记本电脑时,顶部面板指示器会显示预计剩余时间。在电源设置中,内置电池保持不变 - 30%,适配器开启(绿色,闪电),未充电。可更换电池正确停止显示闪电图标和绿色。
当我不插电工作时,笔记本电脑从来不会显示电池电量不足警告,也不会对电池电量不足做出任何反应。它会无缘无故地关机。而且当电池电量不足时,它也不会从挂起状态唤醒。现在我一直担心丢失工作成果并损坏电池(可能已经损坏了)。

更新:sudo tlp fullcharge BAT0
没有开始充电。
更新:尝试通过 USB 实时运行 20.04。内部电池行为相同。
更新:尝试按下笔记本电脑底部的紧急重置按钮,但没有任何变化。内置电池显示已连接到适配器,但并非一直在充电。昨天拔下笔记本电脑时,我实际上看到电池电量下降了几个百分点。连接后,电量似乎没有回升。移除外部电池和适配器后,笔记本电脑无法启动(如果正在运行,则会立即死机)。
答案1
所以这显然是硬件问题。当我安装较新的 Ubuntu 版本时,它同时出现,这可能只是一个奇怪的巧合。
