[Guide] Patching DSDT/SSDT for LAPTOP backlight control

EDIT: Brightness Slider solved. Thank you Rehabman. Reference Post #1232 Page 124.
Only thing left is to map the Brightness Slider.

Hello everyone Good day! I'm a complete newbie and looking for someone to help me.

My problem is with my brightness controls slider.

My laptop is Sony SVF14213SAW, Intel i3-3227u + Intel HD4000.

I applied the pre-Haswell: "Brightness Fix (HD3000/HD4000)" and added ACPIBacklight.kext on my Clover EFI/CLOVER/KEXTS/10.12 and then applied the "Rename GFX0 to IGPU" on my DSDT.

I rebooted and I got the highest brightness and the brightness slider doesn't seem to do anything.

Any help is really appreciated and please bear with me, Thank you.

Actually, it is linked from post #1... I guess you didn't read very carefully.

My bad. Didn't have enough sleep yesterday. Everything is okay now.

Thank you so much for your work.
 
Hi Rehabman,

I have a Surface Pro 2 with CPU Core i5-4200U and HD 4400 graphic.
I tried to follow your guide and install IntelBacklight.kext. I also patched the SSDT (SSDT-8) using the file "graphics_PNLF" (I can't find the file "Brightness Fix" in the link https://github.com/RehabMan/Laptop-DSDT-Patch) and modified the config.plist but the backlight slider still didn't appear. Did I do anything wrong ?
Thank for your help.

BG,

"Brightness Fix" is found in MaciASL when you add the repo correctly to MaciASL->Preferences->Sources.

Read FAQ, "Problem Reporting"

After imported the repo and applied the Brightness Fix patch to the DSDT I got to a bunch of error when I try to save as ACPI Machine Language Library so I decided to re disassembly the DSDT file using iasl download from https://bitbucket.org/RehabMan/acpica/downloads
But I got this warning :
iASL Warning: There were 12 external control methods found during disassembly, but only 5 were resolved (7 unresolved). Additional ACPI tables may be required to properly disassemble the code.

Did I do anything wrong? I already copied all of my SSDT to the same folder.
Thanks.

resulting disassembler output file may not compile because the
disassembler did not know how many arguments to assign to the

runtime and may or may not be available via the host OS.

In addition, the -fe option can be used to specify a file containing
control method external declarations with the associated method

iASL Warning: There were 12 external control methods found during
disassembly, but only 5 were resolved (7 unresolved). Additional
ACPI tables may be required to properly disassemble the code. This
resulting disassembler output file may not compile because the
disassembler did not know how many arguments to assign to the
unresolved methods. Note: SSDTs can be dynamically loaded at
runtime and may or may not be available via the host OS.

In addition, the -fe option can be used to specify a file containing

I disassembled ACPI/origin with: iasl -da -dl -fe refs.txt DSDT.aml SSDT*.aml

The resulting DSDT.dsl compiles without error using MaciASL (linked by my guide) and ACPI 6.1 (see MaciASL->Preferences->iASL).
