Without seeing the resulting code (eg. your edited .DSL), I can't say much about the cause of the error, other than you've made a mistake...

Try my brightness fix (others have confirmed it works with some non-HD3000 machines)...

HD3000/HD4000 Brightness Fix:
DSDT Patches from here: https://github.com/RehabMan/Laptop-DSDT-Patch

Apply:
"Rename GFX0 to IGPU"
"Brightness Fix (HD3000/HD4000)"
- rename patch must be done first and to all DSDT/SSDT that contain references to GFX0 that you're including in your final SSDT set
- Brightness patch must be done to the DSDT or SSDT that contains the definition for Device GFX0 (search for 'Device (GFX0)'
- Place DSDT and SSDT (if necessary) into a place where the bootloader will load them. For Clover, EFI/CLOVER/ACPI/patched (DSDT.aml, SSDT-x.aml where 'x' is a number). For Chameleon, /Extra/ssdt.aml, /Exra/ssdt-1.aml, /Extra/ssdt-2.aml, etc.

You applied the wrong brightness patch. Read/follow the instructions carefully. Don't forget to install ACPIBacklight.kext.

RehabMan said:

Great...



I would assume so... all that is required is a proper patch for AppleHDA and correct DSDT patches to activate it.

Use google to see if you can find a patched AppleHDA already created.
