ykzhao <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #13 from ykzhao <[email protected]> 2010-09-20 07:23:35 --- Hi, Shavkat From the acpidump it seems that there exists the _BCM/_BCL/_BQC object. But after the _BCM object will write the requested brightness level to EC register, the brightness can't be changed. Maybe this is related with the BIOS. When writing the value to IGD PCI config space, it will write the IGD graphics backlight register. Maybe the incorrect ACPI backlight control mechanism is exported on this box.
