klog: HIGH Kernel message: [ 0.831339] [Firmware Bug]: ACPI: No _BQC
method, cannot determine initial brightness is not really a bug.
_BQC is used to get current brightness from BIOS. In ACPI, it was not
listed as mandatory, but it is much needed functional-wise. Linux kernel
will keep trace the current brightness level if _BQC is not present.
We'd like to keep this HIGH as we want to ODM to fix it during
development cycle as much as possible, but this does not hurt any
functions.
