现在用的是X201,装的是Ubuntu,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
design capacity: 8424 mAh
last full capacity: 8492 mAh
battery technology: rechargeable
design voltage: 10800 mV
design capacity warning: 424 mAh
design capacity low: 18 mAh
cycle count: 0
capacity granularity 1: 1 mAh
capacity granularity 2: 1 mAh
model number: 42T4649
serial number: 261
battery type: LION
OEM info: SANYO
cat /proc/acpi/battery/BAT0/state
present: yes
capacity state: ok
charging state: discharging
present rate: 1555 mA
remaining capacity: 1631 mAh
present voltage: 11094 mV
cat /proc/acpi/battery/BAT0/alarm
alarm: 424 mAh
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”
