Linux下 IBM 笔记本电池管理软件

tp_smapi用于控制电池充电和提供额外的电池信息。

 

参考页面：http://www.thinkwiki.org/wiki/Tp_smapi#Battery_charge_control_features

 

Ubuntu集成这个软件自从Hardy以后的版本， 可以直接使用，无需安装。

 

 

电池充电控制

 

设置开始与停止充电的阀值（百分比）

 

# echo 40 > /sys/devices/platform/smapi/BAT0/start_charge_thresh

# echo 70 > /sys/devices/platform/smapi/BAT0/stop_charge_thresh

# cat /sys/devices/platform/smapi/BAT0/*_charge_thresh

（表示低于40%时开始充电，高于70%就停止）

 

 

设置禁止充电时间

17分内防止充电到BAT0（首选电池）:

 

# echo 17 > /sys/devices/platform/smapi/BAT0/inhibit_charge_minutes

 

Hint:

 用于控制给那个电池充电当使用多个电池 Ultrabay battery.

 

 

取消禁止充电:

 

# echo 0 > /sys/devices/platform/smapi/BAT0/inhibit_charge_minutes

强制禁止充电(即使接AC):

 

# echo 1 > /sys/devices/platform/smapi/BAT0/force_discharge

Hint:

用于控制给那个电池充电当使用多个电池 Ultrabay battery. 

 

取消强制禁止充电:

 

# echo 0 > /sys/devices/platform/smapi/BAT0/force_discharge

 

  

显示电池状态信息

 

显示额外的电池状态，比如充电情况、电压、电流、容量、充电次数和型号信息:
