However it may not work either, since my ThinkPad is T430 and I've found at thinkwiki.org: If you are installing on a recent Thinkpad that has an Ivy Bridge or newer processor (X230, T430, T530, etc.), tp_smapi will not work. You will be mostly limited to thinkpad-acpi capabilities. Since acpi_ibm in Linux does work, it's probably not so hard to port those features to FreeBSD. I'll take a look when have spare time. Sergey
