Thank's for your DSDT, I just added comment on bugzilla. This machine support newest WMID GUID3 method but the old WMID_GUID2 method must be also work. I am tracing DSDT for why the WMID2 method return acpi fail, and maybe this machine direct support standard ACPI backlight method. Sorry for I didn't follow up this mail loop and maybe lose some information. Does this machine's backlight control works before 2.6.39 kernel? I mean does backlight control works fine on 2.6.38 or 37 or even older kernel ? Thank's a lot!
