thinkpad電腦如何控制電池何時充電

Download tpctl
http://sourceforge.net/projects/tpctl/files/tp_smapi/

tar zxvf tp_smapi-0.40.tgz
cd tp_smapi-0.40/
sudo apt-get install build-essential linux-headers-`uname -r`
sudo -s
make
make load
make install

電力剩下20%時開始充電

echo 20 > /sys/devices/platform/smapi/BAT0/start_charge_thresh

電力到達100%時停止充電

echo 100 > /sys/devices/platform/smapi/BAT0/stop_charge_thresh

不強制充電

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