As for _OS, that is only crasp. Note that you can pass the acpi_os_name='' if you want to change _OS so that some method may work 'better' for you. Sometimes, it may help to try others values, but YMMV. Note also that only some thinkpads have _OS == 'Linux' related stuff implemented in their DSDT, but it seems that it is not well used though (at least, IBM do care of that, even if it is not perfect). I don't find that others vendors do care of others OS other than redmond' one. But it is for laptops/desktop word. To be fair, _OS seems not to be used in servers. -- Ducrot Bruno -- Which is worse: ignorance or apathy? -- Don't know.
