I have a problem with brightness...i patched the dsdt for bightness and i have the bar in the display but when a move it up/down doesn't work...any help??

Thank you for your time rehabman...always giving us the best solutions!!!Keep it up:clap:

So i must search for an ELAN kext and replace it with voodoops2 correct??

I send the wrong dsdt file :P I fix it my sound works just fine now!!!One last think...when i first install osx my trackpad worked fine,but now every time i use it getting crazy when i touch it!!!I used voodoops2.kext...what happened??

Is that correct??

Ok i'll try it from the beginning...for the patch should i use ACPI 6.1??

Here you are

I used the patched Dsdt(to save some time) from post #1 and copied into clover/acpi/Patched.Everything works except the audio!!!

I installed the applehda for conexant CX20751/2 which i found there (http://www.tonymacx86.com/yosemite-laptop-support/151002-lenovo-e540-thinkpad-yosemite-clover-work-progress.html) in S/L/E via Kext utilities but no audio at all!!!Any help??

First i try it with ACPI 5.1 and gave always one error,but indeed with ACPI 6.1 it gives 0 errors!!!Should i fix those warnings or it doesn't matters??

Anyone can help me with this...i can't fix this error!!!

Ok man...thank you again!!! :headbang::clap:

I think i find somthing...thanks...this kext must be installed on L/E right?

Now you can use google to find a patched AppleHDA for it... I cant't find anything about Conexant CX20751/2 in google.Everything works graphics,brightness,sleep,trackpad,keyboard expept the audio!!!

You are right...that's the onboard audio!!! It's seems that i have Conexant CX20751/2

I manage to create the codec dump text from linux but i can't find the codec!!

The AppleHda for Conexant CX20751 it's not on the list that you provide!!!

Ok rehabman...i'll give it a try...thank you!!!

I have a question...that dsdt for battery,brightness colour etc...works also for mavericks??
