------- Comment #16 from yakui.z...@intel.com  2009-02-23 00:21 -------
Hi, Carlos
    Sorry for the late response.
    What Rui said in comment #14 is correct. There exist the ACPI objects of
_BCL/_BCM. But  unfortunately the _BCM is the bogus object. It will do nothing.
In such case if the generic acpi video driver is used to change the brightness,
it will have no effect.
    >Method (_BCM, 1, NotSerialized)
     {
     }

     At the same time there is no ACPI object(FUJ02B1/FUJ02BF), which causes
that the fujitsu-laptop driver can't be loaded correctly. Of course the
brightness can't be changed by the fujitsu-laptop backlight interface.(sys I/F
or proc I/F).

    Thanks.
