现在用的是X201,装的是Ubuntu 10.04,前两天换了9芯的电池,想看看是不是零充电,充电的百分比都看不到,后来发现如下的方法,值得留下,备用:-),
在ubuntu里,电池所有相关的信息都在 /proc/acpi/battery/BAT0/ 文件夹下的文件中记录着,好像笔记本都是BAT0,因为大都只有一块电池哦,这个文件夹下有alarm info state 三个文件,终端下输入:
cat /proc/acpi/battery/BAT0/info
present: yes

last full capacity: 8492 mAh

cat /proc/acpi/battery/BAT0/state

cat /proc/acpi/battery/BAT0/alarm

看看还是很详细的,比Thinkpad自带的还好,^_^,另外发现一个图形的界面,如下操作:
Alt+F2,输入“gnome-power-statistics”
