If you follow the guide and instrument your EC queries, I think you'll discover your brightness keys are handled in method _Q11 and _Q12 (because I see Notify(.., 0x86) and Notify(.., 0x87) there which is the Windows mechanism for brightness keys).

i followed the guide and did the "instrument EC queries" and in the console, in system.log the result was the same as the last time...

ACPI is not patched correctly.
DropOem=true is required with patched SSDTs in ACPI/patched.
Make sure you're pressing the same brightness keys as are used in Windows (test on Windows so you're certain you know what they are).

thanks for the help... but could you tell me more precisely what isn't correct in the ACPI patching?
the DropOem=True will activate now..
and the keys i'n sure i'm pressing the right ones. but there is some keys on the keyboard that don't work... i don't work... i just don't remember if the FN is one of them.... and i can't try on Windows... this laptop only have OSX....
