    Thinkpad X230T, tp_smapi kernel module

    OS: Ubuntu X64

    check the Battery information
    Code:
    cat /proc/acpi/battery/BAT0/info
    Then, I install tp_smapi kernel module
    Code:
    sudo apt-get install tp-smapi-dkms

    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.
