linux – 如果在桌面上,包UPower输出是什么？

在Ubuntu 12.04上,如果我使用命令：

    upower -i /org/freedesktop/UPower/devices/battery_BAT0

它将输出电池的所有统计数据.但是,如果我使用的是台式机,它会输出什么(即没有电池？)

解决方法:

从工作站：

$upower -i /org/freedesktop/UPower/devices/battery_BAT0

输出：

failed to set path: cannot refresh: Cannot get device properties for
 /org/freedesktop/UPower/devices/battery_BAT0: Couldn't call GetAll() to 
 get properties for /org/freedesktop/UPower/devices/battery_BAT0: Method
 "GetAll" with signature "s" on interface "org.freedesktop.DBus.Properties"
 doesn't exist
