Power Management is not applied correctly neither activated.(from the files on the post you posted and discussed with rehabman)
You uploaded a blank config.plist on the new files.
Also ACPI wasn`t patched correctly.
Thats definetly a bad practice,it will just mix things up.
Your audio had no Audio Layout Injected on DSDT so ofc it wont work,HDAEnabler is a kext that enables specific layout ID (which is the number of the id of your codec that is used in the patch)
ALC293 vs ALC292 a different codec from each other,sometimes even two same Codecs ID`s are different from 1 laptop to the other.
CodecCommander fixes the issue when after you sleep/wake laptop you lose sound. EAPDfix is the same but older kext and system of patch.
We will get back to it later.
Installing them on your partition is a must for your machine to work properly.
They won`t cause conflicts because its the same kext and loads directly from the installation and also same kext cant be loaded twice.
its needed on ESP only for installation purpose.
Remove everything from ESP and just Leave:
FakeSMC,VoodooPS2Controller,AppleIntelE1000,ACPIBatteryManager.
Remove EAPDfix and ALC292 kext that you use.
Install these kexts into System/Library/Extensions(you already have some of them and i will attach the others:
- FakeSMC
- VoodooPS2Controller
- ACPIBatteryManager
- AppleIntelE1000
- IntelBacklight (instead of ACPIBacklight since you have Intel HD Graphics Card)
- FakePCIID
- FakePCIID_Intel_HD_Graphics
- FakePCIID_HDMI_Audio
- USBInjectAll (instead of genericUSBXHCI if you have Intel Chipset/USB)
- AppleALC (for audio)
- Lilu (Kernel for AppleALC)
- CodecCommander
- Shiki (Used with Intel Graphics fixup to fix sierra freezing issues with HD4400/4600/5000)
- IntelGraphicsFixup
try the config.plist that i provided,kexts,ACPI/Patched(leave them as they are and test if things work)
Report back with results,i don`t know for sure if everything will work since i don`t own a T540p but if everything does,i will report back here and tell you what i exactly did so you can learn and don`t need help in the future,even though Rehabman and others guides there are very detailed and clearly explained which they spent so much time for making them so they cover everything for us to have so much easier time fix our machines but some are lazy to read and fix on their own,some just can`t get it at some point.Anyway.
Report back what is working,what is not working.
