I'm not familiar with OpenCore but according to the DSDT, Skip 15 (for GPI0 /_sta-> xsta) and 32 (for tpd1 /_crs-> xcrs) are now correctly replaced.

Can you post IOReg with the skip 15 Config?

hmmm. touchpad work after sleep.

Here is ioreg skip15_ater_sleep.zip

P.S.

Work after sleep , when i boot from flash. If i move EFI to SSD, - touchpad not work after sleep. I think , sleep work not so good in OC. in AC Power - instant wake.

CustomSMBIOSGuid: Performs GUID patching for UpdateSMBIOSMode Custom mode. Usually relevant for Dell laptops.

Enabled this option. Nothing change.

 

Current bug in OpenCore:

1. Touchpad work only when i boot from USB flash and only after sleep. Part fixed. Touchpad work only after sleep.

2. Sleep not work when i boot from SSD, instant wake.  Part fixed. Sleep work only for battery. 

3. Reboot option hung when i booting in OC, when i want to reboot macos, macos shutdown correct, but black screen hung and no reboot. shutdown are work correct.  Fixed.

4.In about menu no serial /model information:

Catmater, I have the same laptop as you.  I have clover bootloader with Catalina working good on it too.  Was going to try OpenCore when I stumble upon this post.  Post any updates if you can.
