Thinkpad X230T, tp_smapi kernel module

[maxchen]

OS: Ubuntu X64

check the Battery information

cat /proc/acpi/battery/BAT0/info

Then, I install tp_smapi kernel module

sudo apt-get install tp-smapi-dkms
sudo modprobe tp_smapi

FATAL: Error inserting tp_smapi

any help?

start windows 7, set the threshold.
Back to Ubuntu 12.04, the thresholds are working!

Hi,

unfortunately tp-smapi doesn't work with Ivy Bridge models. Instead you have to use tpacpi-bat/acpi_call. You may use TLP to do this.

thanks!

from http://linrunner.de/en/tlp/docs/tlp-configuration.html , I found that
"Hint: the charging process is not controlled by software, but by hardware. TLP just writes the thresholds to the hardware registers (via tp-smapi or tpacpi-bat)."

Thus I set the thresholds in win 7 works, I do not need to install TLP or tp-smapi-dkms

Damn. I shouldn't have written that one into the docs .

In case you don't want to optimize power consumption any further from plain vanilla Ubuntu – then you don't need TLP.

Thanks for your great work, I really appreciate it.
