安装前请先阅读http://www.thinkwiki.org/wiki/Tp_smapi
下面我介绍下我的安装过程。
安装的时候，首先需要创建source的链接（当然了，内核版本不同目录需要相应的变化下，可以用uname -r来查看）
代码： 全选
cd /lib/modules/2.6.27-7-generic/
ln -s /usr/src/linux-headers-2.6.27-7-generic/ ./source
代码： 全选
make
sudo make load
sudo make install
输入
代码： 全选
dmesg |grep thinkpad
代码： 全选
[ 19.144704] thinkpad_acpi: ThinkPad ACPI Extras v0.21
[ 19.144710] thinkpad_acpi: http://ibm-acpi.sf.net/
[ 19.144715] thinkpad_acpi: ThinkPad BIOS xxxxxxx

[ 19.145822] thinkpad_acpi: radio switch found; radios are enabled
[ 19.146068] thinkpad_acpi: This ThinkPad has standard ACPI backlight brightness control, supported by the ACPI video driver

sudo gedit /etc/modules
代码： 全选
sudo update-initramfs -u
代码： 全选
modprobe -a tp_smapi
例如从40开始，70结束。
代码： 全选
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
注意：此模块会和HDAPS模块冲突。http://www.thinkwiki.org/wiki/HDAPS而其内建的HDAPS不支持hdapsd，所以我没装。望达人指导。
用于查看电池信息的脚本
