问题
电池指示灯的状态存在一些问题。
我列出了电池状态的一些信息，如下所示：
$ cat /proc/acpi/battery/BAT0/state
present: yes
capacity state: ok
*charging state: charged*
present rate: 0 mW
remaining capacity: 18200 mWh
present voltage: 16103 mV
电池指示灯状态
电源设置面板
有什么方法可以解决这个问题？
sudo fwts battery - > battery.log
3 passed, 4 failed, 0 warnings, 0 aborted, 0 skipped, 0 info only.

答案1
尝试使用fwts测试环境：
sudo add-apt-repository ppa:firmware-testing-team/ppa-fwts-stable
sudo apt-get update
sudo apt-get install fwts
acpi
noefi
acpi_osi
apm
你也可以尝试用acpi程序测试输出参数：
sudo apt-get install acpi
acpi -V
