Hi, Rehabman.
I have an ASUS A46CA and almost work on all with DSDT
What it worked:
>Integrated Camera
>Keyboard and Multi-Touch pad + gestures
>Fn (Moved to the Context menu + fx)
>Sound (Integrated Speaker + Integrated Mic)
>HD4000 (Device-properties 0x01660003)
>Speedstep (SSDT suggestion from mrkonow)
>Sleep
>Ethernet (it will scramble the IP if I unplug and re-plug the cable while on OS X)
>Brightness control (added PNLF on DSDT)
>USB3 Detected (haven't tested it yet) (Thanks to RehabMan for the GenericUSBXHCI.kext)
>LID Sleep (don't know what did I do, only make the build almost 100% Vanilla (I'm using Injectors like Voodoo))
>Battery Percentage Detected (VoodooBattery + custom AppleACPIPlatform)
>Headphone solved, even get sound after sleep (from patched AppleHDA into VoodooHDA. Thx to PJALM for suggesting Vanilla Build)
What it don't worked:
>WiFi (AR9485) (Detected but no drivers) + Bluetooth (detected but won't search and receive) <- it's combo (AR9004WB)
>Realtek SD Card Reader (Not detected)
Thx for helping
