My brightness key on my keyboard are fn+arrowup and fn+arrowdown key. Currently, it's remapped to fn+insert and fn+f3 key. Is there a way to fix this? Thanks

More info:

I tried ACPIDebug and it always log EC _Q66 for all keyboard hotkeys

In the Attachment, there are the info.plist of voodoops2keyboard which I found many mapping there and also my DSDT.aml (Which patched by guys from osxlatitude forum).

Can you attach your DSDT from origin? Which version of VoodooPS2Controller are you using?

VoodooPS2Controller: http://forum.osxlatitude.com/index.php?/topic/8285-refined-alps-touchpad-driver/page-48&do=findComment&comment=65797

I think I use the latest Keyboard plugin from Rehabman 

Origin DSDT:origin.zip

Thank you very much

P/s: A few other hotkeys: 

Fn+F1:Sleep

Fn+F2:Numlock

Fn+F3:Scroll lock

Fn+F10: Previous track?

Fn+F11:Play/pause

Fn+f12:Next Track?

Motherboard: AMIBIOS?

CPU+GPU:IvyBridge i7

Supposing that you have a working brightness slider in System Preferences.

Try this version of VoodooPS2Controller.kext: https://bitbucket.org/RehabMan/os-x-voodoo-ps2-controller/downloads/RehabMan-Voodoo-2017-1130.zip

It maps brightness keys to F14 and F15. The other hotkeys should work OOB.

Your _Q66 Method calls NEVT Method which calls EVxx Methods. Try to debug brightness hotkeys with this DSDT.

Here is the result for both up and down brightness hotkey: 

ACPIDebug: "EC _Q66 enter"

ACPIDebug: "EV4 (0x0800,Zero)"

 

Here is the Log of ApplePS2Keyboard with LogScanCode 1

Arrow up:ApplePS2Keyboard: sending key e048=7e down

Arrow Down: ApplePS2Keyboard: sending key e050=7d down

P/s: I don't use any Backlight kext from Rehabman or from any other hackintohser. I use native one, untouched from Apple.

See my guide for Dell Laptop. The link is in my signature.

Briefly

1. I don't use any Brightness kext.

2. I don't patch DSDT for brightness.

3. Brightness hot keys are F1 and F2 as it should be for real Mac.

4. My version of VoodooPS2Keyboard + VoodooPS2Trackpad by DrHurt.

I have full brightness control for both cases Optimus=Enable/Disable.

But The problem is the Fn+F1 key will hibernate the Operating system. When I boot up again, It completely freezed

Could you please enable that from my DSDT please? I couldn't find anywhere to insert the patch. Thanks

We've made a working code with Rehabman but since Sierra it becomes useless. It's an known issue, the brightness up key lowers also the volume.

The EC query _Q66 is the right place but only useful @10.11 and earlier.

You have removed the WMI code from this DSDT, but it is needed for the brightness key fix. If you upload a DSDT with the WMI part I'll add the code to it, also a kext by Dr Hurt (which you're probably use) with the ADB Map fix.

 

No such issue in current macOS 10.12.6/10.13.x.

No more!

You've changed the ADB codes on your VoodooPS2.kext, but your trackpad code does not support ALPS trackpads. I think the most ALPS user are using Dr Hurts kext without changed ADB codes.

The ADB mapping of the kext was untouched.

P/s: the kext in the Archive.zip may be touched without intention, Please get the original one from http://forum.osxlati...e-48#entry65797 Thanks

I have re-added some AMW code from the original dsdt to the one i sent you.

Archive.zip

Trying to patch DSDT myself. The brightness are now only controlled by the FN+F3 and FN+Insert key. The Fn+Arrow(Which I couldn't managed to get the scancodes) stop changing brightness independently now!DSDT 2.zip

What a pity that it doesn't work as expected

Brightness still map to fn+f3 and fn+Insert instead of fn+Arrow up and down

Does it work with the WMI kext? Is it the E6430?

Here, the DSDT patch works again after the ADB map fix on a E6420, thanks to Rehabman.

I'm on the E6230. The fn+Arrow seem stop changing the brightness, make the Fn+f3/Insert the only way to change the brightness.

kernel	ApplePS2Keyboard: sending key e045=71 down //Fn+ Insert: cause the screen brighten up
kernel	ApplePS2Keyboard: sending key 46=6b down   //Fn+ F3: cause the screen brighten down
kernel	ApplePS2Keyboard: sending key e048=7e down //Arrow Up
kernel	ApplePS2Keyboard: sending key e050=7d down //Arrow Down

Here is the only related scancodes I could fetch Fn+up and Fn+Down doesn't result in scancodes:Only ACPI _Q66

The brightness keys are ACPI controlled, so no scan codes.

The DSDT I've uploaded was a .dsl file, have you saved it as binary?, if not here is the .aml. DSDT.aml.zip

caused the computer freezed when press fn+arrow or fn+f3/insert. took a few reboot early to get back on.

That's a good sign, it seems that the code does something. But your DSDT is a mess, you've added the WMI device to the wrong place. Other code is missing.

Here is the DSDT from Slice, with the brightness code it is probably the same, try it. But, I recommend you to create a new DSDT with the brightness code.

System abrupt when press Fn Arrows with this DSDT(I try to edit the dsdt that i received from osxlatitude). I couldn't patch the dsdt from beginning.

Maybe your laptop needs other codes, try it with the WMI kext below, it's a debug version. Look at the Console.

I think it's better to patch a new DSDT, press F4 @Clover menu and upload the DSDT.
