Alps touchpad on Dell Latitude 5580 not working - Catalina 10.15.3

[Keronei]

There's the Internal Intel wifi card, which has a Bluetooth that is USB based, that seems to be the only networked USB device. It doesn't work either, although I configured it in UIAC with connector type 255 (internal).

 

I use the external mouse & keyboard as well.

 

What are the specific configurations which makes the touchpad recognised(from your config pack) ? maybe I can just work with that for now(with the previous configuration) until I manage to get the DSDT patch detected.

Did you add the DSDT back with files I attached? You suppose to replace all the files and not merge.

The SSDT's + DSDT renaming in Config file are hot patches that replace any DSDT patching, so no DSDT is needed.

Try disabling or removing the Intel wifi/bluetooth to fix the sleep issue.

 

If you want to use your files and patch the DSDT for touchpad, here're the patches you'll need to apply

I'll just remove the Intel card altogether because it has no job.

 

Initially, I didn't merge the files. I kept a backup of all the clover folder and deleted everything in /patched and placed the ones you sent, did same for config.plist and did as instructed for the kexts(excluding the Broadcom ones because I don't have any Broadcom chip).

 

I will patch the DSDT with the what you've provided and report progress. I can't predict how long it will take but will ultimately report back.

 

Thanks again.

and one more, the ambient light sensor, if I can also get that...posibly it will be better.

Just add the SSDT-ALS0.aml to the patched folder
