如果我在笔记本电脑关闭时插入电池，电池指示器就会消失。我使用的是带有 Unity 桌面的官方 ubuntu 14.04。在系统设置中，为“在状态栏中显示电池”选择了“当电池存在时”选项。如果我在笔记本电脑开机时插入电池，它就可以正常工作。在 13.10 上，它可以正常工作。我全新安装了 14.04。有什么想法吗？
编辑1：这是输出ps ax | grep indicator-power-service：
2709 ? Ssl 0:00 /usr/lib/x86_64-linux-gnu/indicator-power/indicator-power-service
12133 pts/1 S+ 0:00 grep --color=auto indicator-power-service
编辑2：这是的输出upower --dump。笔记本电脑使用电池供电且未插电，但没有电池指示器：

答案1
你可以在权力中找到它
=> 显示电池状态 => 目前
如果这不起作用请尝试
重新安装指示器电源
sudo apt-get purge indicator-power
sudo apt-get install indicator-power
如果你有配置编辑器
com => appmenu => power => 右键点击 =>
如果你没有则显示
别的
sudo apt-get install dconf-editor
重新开始
答案2
您是否尝试将图标设置为“始终开启”？请参阅这里。
如果您知道要手动运行什么才能恢复图标，则可以编写一个脚本，在设备恢复时调用该脚本。我运行 Xubuntu，因此对我来说有一个 xfce-power-manager。也许对您来说它是 gnome-power-manager？
如果这样可以恢复图标，那么类似这样的脚本/etc/pm/sleep.d/11_power可能会有所帮助。尝试以下操作：
case "${1}" in
resume|thaw)
gnome-power-manager
;;
esac
确保其可执行sudo chmod +x /etc/pm/sleep.d/11_power
答案3
在关机状态下安装电池时是否还插着电源？如果在首次打开电脑时电脑没有检测到电池，那么这几乎就是电池坏了。
答案4
转到“设置”>“电源”> 在“菜单栏中显示电池状态”下，确保将其设置为“当有电池时”
