1- Apply PNLF Patch or use SSDT PNLF

 PNLF for Sandy Bridge / Ivy Bridge / Haswell / Broadwell / Sky Lake / Kaby Lake processors

SSDT PNLF-KABY-.aml.zip

DSDT patch

into_all device label PNLF remove_entry;
into scope label _SB insert
begin
Device (PNLF)\n
        {\n
            Name (_HID, EisaId ("APP0002"))  // _HID: Hardware ID\n
            Name (_CID, "backlight")  // _CID: Compatible ID\n
            Name (_UID, 0x10)  // _UID: Unique ID\n
            Name (_STA, 0x0B)  // _STA: Status\n
        }\n
end

 

PNLF for Coffe Lake / Whiskey Lake / Comet Lake / Ice Lake processors

SSDT  PNLF-COFFEE+.aml.zip

DSDT patch

into_all device label PNLF remove_entry;
into scope label _SB insert
begin
Device (PNLF)\n
        {\n
            Name (_HID, EisaId ("APP0002"))  // _HID: Hardware ID\n
            Name (_CID, "backlight")  // _CID: Compatible ID\n
            Name (_UID, 0x13)  // _UID: Unique ID\n
            Name (_STA, 0x0B)  // _STA: Status\n
        }\n
end

 

2- Brightness Keys

Use BrightnessKeys.kext for automatic handling of brightness keys based on ACPI Specification

On some Laptops, may be required ACPI patch _OSI to XOSI and SSDT-XOSI.

How can I do this patch with an SSDT? I am looking for a way to just use SSDTs with OpenCore.

in this case u need use rename

example

_Q11 to _Q1x and inject SSDT with new remap

I have made some progress but not there as yet. This is my final issue that I am trying to resolve. The brightness keys should be fn+f3 for up and fn+f2 for down.

I have the renames but the SSDT has an issue. What am I doing wrong?

first u need check what methods _Qxx u need rename

check the name of the device ps2 too

I have done that. It is _Q1C and _Q1D  and I have already done the renames. I am not sure what code I need for fn+f2 and fn+f3.

When I press the brightness keys the PC reboots. I did the rename _Q1C to XQ1C and _Q1D to XQ1D. IS that incorrect ? If not, what should it be?

u have a dual boot?

Yes I have a dual boot but just wanted to see if I can get everything working with SSDTs. This is the only thing I have outstanding and I just can't figure it out. Everything else is working fine. 

I do have a DSDT that you did.

 

[MaLd0n]

ye

devs need fix that

 

[Deihmos]

I got it done. The code was not correct. Now I have everything working with SSDTs.

I don't use OpenCore for dual boot because I don't want my PC to act like a Mac. Hopefully an option is added to disable it. 

[MaLd0n]

if u dont use dual boot why use a incomplete solution provide by SSDT. use full DSDT patched

is there a PNLF Patch for comet lake?

I use dual boot. I also have the DSDT but I don't see any difference between using the SSDTs vs DSDT. I get the same results but can dual boot with the SSDTs.

 

voodoops2 now handles ACPI notification for brightness keys without any patches.

have many difference. with ssdt the system is always a little slippery

but if u reaaly need dual boot and need boot windows from opencore, use ssdt

i'm using bootkey

 

[Deihmos]

Ok thanks for the info. I have explored using rEFInd for dual boot. 

[Israel Serrano]

Thanks a lot🤙

Enjoy!

@Deihmos could you please share the ssdt code (and oc renames) that worked for you?

Im trying to do the same thing with SSDT for HP Elitebook 840 G6.

Thank you for the quick reply @MaLd0n!

I dont know what is my problem exactly, my special keys (fn+f3 and fn+f4) controls brightness perfectly, but everytime I reboot from Windows, it doesn't work anymore (if I hold power button for 30secs to reset my EC, or something ... then it works again, but always after windows stops working).

I tried this kext but reboots always when I try to load it. I dont use any special SSDT or DSDT patches for this. I tried booting with "-v" and "-brkeysdbg" for debug output, but I got nothing meaningful. Just freezes while booting with this kext.

TY

Hello, i've done use this method to fix my FN Brightness Key. But it's work with FN+S for brighness down and FN+B for brightness up. Can u have solution to change that mapping to FN+F11 and FN+F12. Thanks before ☺️
