Your DSDT is strange, can you PM me with your ACPI dump extracted from either windows using (AiDA64 v2) or linux according to my DSDT/SSDT patch thread so i can help you?

You don't need my display backlight driver and its only for notebooks up to Intel second generation notebooks. You need Fn keys drivers for your real fn key and ELAN driver for touchpad. Your problem with Keyboard backlight is because of this line in SKBL "^^PCI0.LPCB.EC0.WRAM (0x044B, Local0)". Your original method uses "0x44B" instead of "0x4B1" found in Haswell notebooks. So, correct this and you will get your keyboard backlight working.

What is your problem exactly? Could you explain? Try the new version v3.8 and let m know.

Try the new version v3.8 and change the scroll speed from the trackpad prefpane to get it working. Please read my features explanation thread for details on everything so you can understand. If you have any problem then PM me. Your touchpad problem has been fixed in the new version. Try that and let me know.

For scrolling, try to change the scroll speed and enable the scrolling from the trackpad prefpane at System preferences.

Try the new version and PM me if you still have the problem so i can help you.

I've uploaded new version v3.8, try that and let me know if you have problems though PM so i can fix them and improve the features. PS: Read my features explanation thread for details on new changes and features to understand their usage.

You have optimus nvidia card which is not disabled, so try disabling that and see. Also let me know see your Extra folder and your system log for the boot which takes so much time and which boots quick.

Well, windows drivers you are using might be using different firmware than my kext uses in OSX. So, dual booting with system restarts may give problems. You said something about sleep wake issue before, is that still there?

AR3011 bluetooth uses standard drivers of OSX which doesn't provide bluetooth on/off toggle which i have already explained in the first post. I'm trying to find a workaround for this and its in testing. I will post that solution if its working fine.

Send me your System log and ioreg file so i can take a look at your problem.

Use the IOregistryExplorer app v2.1 or lower (google) and save a file from file menu in that app, for system log open Console app found in OSX and look at the left menu then right click on it and choose shown in finder for that file. Send me the above two files and your DSDT so i can help you.

PM me for beta testing your touchpad.

For scrolling you need to change the speed of the scroll once to get it working after installing my driver.

Do you have ELAN touchpad in your notebook? Also did you remove all the kexts i mentioned in the How to install section? Share your KP picture and ioreg file if you have ELAN so i can help you.

Bluetooth will work if you use my kext and you don't need to boot Windows for activating that. If you have any problems with my kext then send me your system log and ioreg after booting with my kext installed so i can help you.

Can you send me your logs for 10.9.2 and your working 10.9.1 kext?

Try this and send me know your system log/ioreg if you have problems. Use the layout 28 DSDT patch. AppleHDA_Patched__ALC269_2.1.zip

PM me so i can send you debug kext to test and fix this issue. Please explain your issue again in PM with details.

Let me see your DSDT, ioreg and system log. Also provide your notebook specifications.

Yes, next update will enable this from plist. Fn mode 1 makes the Function keys as Fn keys so you will lose the Function keys. If you want Function keys then you use mode 2 and 3 (or) switch between the modes using the keyboard shortcut Caps + Shift + F on the fly. Keyboard backlight is only for Asus notebooks and it can be enabled by editing plist and you need to use the DSDT patches i've provide in the features explanation thread.

You need to use DSDT patches and AsusNBFnkeys kext from projects section.

Send me a private message and I'll give you debug kext for testing then you will send me logs i needed for solving this issue.

These ids are not supported added in 2.3, will be done in next minor update. Try to add your ids like i explained in the post and it will work.

Does it has Nvidia GPU only? If so PM me for more details on this.
