『转』ubuntu的电池管理
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:
