you could try adding all ports, something similar to this:

hackintool can help you with that

I follow this guide https://www.tonymacx86.com/threads/...ching-guide-hdmi-black-screen-problem.269149/
Now works, but not allways. Sometimes persists the black screen and others i boot works fine.

Now i'll try to fix the shut down problem and the batery patch. I followed the open core guide but doesn't works.

as you have setup your usb ports, you need to disable:
XhciPortLimit

also I don't think that a DSDT should be used with OpenCore

 

[Guiltys33d]

DSDT should be used with OpenCore

If it's excluded, how do you get battery management and battery status?

just by using VirtualSMC.kext and SMCBatteryManager.kext, the battery showed up automatically

With only this kexts doesn't work on my laptop. I follow this guide https://dortania.github.io/OpenCore-Desktop-Guide/post-install/pm.html and doesn't work too to fix the shutdown problem and batery status.

shutdown problem

Set your BIOS to EFI only,
disable BOOT on LAN

Open your laptop and remove both the small and big batteries inside for about 2 mins
then

reset it to default after you've re assmabled it back together

and lastly

Set your BIOS to boot on EFI only,
disable BOOT on LAN
disable your dGPU
disable your Virtualization

and try again
