在Linux的终端检查笔记本电脑电池的状态和电量
通过三种方法从命令行找到笔记本电脑的电池状态。
方法1-使用"Upower"命令
大多数Linux发行版中都预装了Upower命令。要使用Upower显示电池状态，请打开终端并运行：$ upower -i /org/freedesktop/UPower/devices/battery_BAT0
示例输出：native-path: BAT0
vendor: Samsung SDI
model: DELL 7XFJJA2
serial: 4448
power supply: yes

has history: yes
has statistics: yes
battery
present: yes
rechargeable: yes
state: fully-charged
warning-level: none
energy: 33.4443 Wh
energy-empty: 0 Wh
energy-full: 33.4443 Wh
energy-full-design: 48.84 Wh
energy-rate: 0.0111 W
voltage: 12.446 V
percentage: 100%
capacity: 68.4773%
technology: lithium-ion
icon-name: 'battery-full-charged-symbolic'
如你所见，电池已充满，电池电量为100%。
如果以上命令因原因不能工作，请尝试使用以下命令：$ upower -i `upower -e | grep 'BAT'`
示例输出：native-path: BAT0
