if u use voodoops2 with VoodooInput.kext, remove this plugin inside VoodooI2C.kext to avoid conflict. both kexts have this plugin

It means when my laptop completely turn off, I can not power on my laptop if not plug in the charger, as this picture:

With your above DSDT, I can do that but unluckily it’s boot stuck

For touch screen, I go inside to VoodooI2C kext —> Show Content —> Plug ins —> Delete voodooinput but still nothing change

All after hairs fallen, I've fixed the problem of lid wake/sleep wake --> It's by AAPL,ig-platform-id, the previous one I choose wrong (do not know why the screen can go inside), now I use the value 00001E19 --> It's run smoothly.

For the problem when shut down laptop, if not connect charger can not turn on laptop by power button --> My battery health still 80%, I think research later because my laptop always go with charger. A little bit inconvenient by need charger the same as starter of car when laptop fully turn off, without starter no power on.

Now remain only how to enable my ELAN Touch screen. I do not know just paste the kext to OC folder or need to do other steps more like PIN configure, SSDT GPI0, XOSI...? Could you please guide for me the way to enable it?

? Please help me, I ask because I really do not know that word.

When I put the kext, touch pad ok, recognize.

but for touch screen, do you think that need to set up Pin configurator?

usb devices in many cases just need kexts inside bootloader folder ;)

In Catalina, I can go over by put VoodooI2C and VoodooI2C HID into Library/Extention. May be that way support to load kext into bootloader. But in Big Sur, may be Apple lock to put kext into LE
