安裝tp-smapi:
# aptitude install tp-smapi-dkms
# modprobe tp_smapi
更改充電阈值：
設置開始充電阈值，如從“60%”開始充電：
# echo 60 > /sys/devices/platform/smapi/BAT0/start_charge_thresh
設置停止充電阈值，如到“100%”停止充電：
# echo 100 > /sys/devices/platform/smapi/BAT0/stop_charge_thresh
查看充電阈值：
# cat /sys/devices/platform/smapi/BAT0/*_charge_thresh
其他：
To prevent charging for 17 minutes (regardless of thresholds):
# echo 17 > /sys/devices/platform/smapi/BAT0/inhibit_charge_minutes
To cancel charging preventation:
# echo 0 > /sys/devices/platform/smapi/BAT0/inhibit_charge_minutes
To force battery discharging (even if connected to AC):
# echo 1 > /sys/devices/platform/smapi/BAT0/force_discharge
To cancel forced discharge:
# echo 0 > /sys/devices/platform/smapi/BAT0/force_discharge
讓設置在啟動時生效（只用同一塊電池）：
It is not necessary to create your own init.d script or modify /etc/rc.local - you just need the package sysfsutils:
# apt-get install sysfsutils
# sudo gedit /etc/sysfs.conf
把下面的放在文件 /etc/sysfs.conf後面:
# cat >> /etc/sysfs.conf << EOF
# For a LiIon battery in a Thinkpad
devices/platform/smapi/BAT0/start_charge_thresh = 50
devices/platform/smapi/BAT0/stop_charge_thresh = 80
EOF
The init script supplied by sysfsutils will load these settings on each boot.
