尝试indicator-power使用以下命令重新安装：
sudo apt-get install --reinstall indicator-power
如果那不能解决问题，请考虑使用我以前的回答之一提供的电池监视脚本：https : //askubuntu.com/a/603322/295286
以下是python脚本，可以在电池电量超过一定百分比时通知您，并在电池电量达到10％之后挂起系统。用法很简单：
python battery_monitor.py INT
其中INT是所需电池百分比的整数值，例如30。
您还可以将以上命令添加到启动应用程序，以在每次登录Unity会话时启动此脚本。
源代码
根据聊天和评论中的OP请求，脚本现在带有两个参数，第一个用于放电通知，第二个用于充电通知。
也可用作Github Gitst

indicator-power包。如果你愿意，我还可以提供一个脚本，可以给你通知。
