jones333333 Posted October 30, 2020 Share Posted October 30, 2020 Hey Jake Lo i just acquired a 820 g3 model. I think it's very similar to your 840 G3 model as I used your OC folder and could directly install Catalina on it! This laptop is blazing fast with Catalina it really feels like a real MAC. I plan to use your OC folder as basis for my config but I would like to use my own patched SSDT's as think it will be even better performance of the overall system. Do you think you could help me with this? ACPI DUMP.zip jones333333.ioreg.txt.zip Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted December 8, 2020 Moderators Share Posted December 8, 2020 You have audio layout-id set to 15, it should be 13 My fault, i'll update the files later but for now, you can change it under NVRam, set alcid=13 New files uploaded with OC 0.6.4 Link to comment Share on other sites More sharing options...
jones333333 Posted December 12, 2020 Author Share Posted December 12, 2020 Thanks a lot for your help Jake Lo, I did update my files with your last OC files and everything is working now! Jake Lo, are you able to use the usb C port on the HP to connect to an external screen? Link to comment Share on other sites More sharing options...
jones333333 Posted December 14, 2020 Author Share Posted December 14, 2020 Jake Lo, may I ask you some informations regarding some files that you are using in your OC configuration as I am trying to better understand how the whole ACPI patching is done. What is the purpose of the SSDT-840G3.aml file in the ACPI folder ? really want to understand all the steps that you followed to patch your ACPI but it is quite complex. Also I see that you all the ACPI patches in your config.plist are enabled. Are these patches applying on the DSDT of the machine or on the SSDT files ? Thanks in advance for your help.

Moderators Jake Lo Posted December 14, 2020 Moderators Share Posted December 14, 2020 As you see in the guide, the credits to the SSDT patches goes to Rehabman. They are hot patches that apply to the DSDT during boot. Patches in SSDT-840G3 includes the following: Audio layoutid Battery Status Sleep / Wake USB Port EC SBUS PS2K The others are from Dortania's OC guide Link to comment Share on other sites More sharing options...
jones333333 Posted December 14, 2020 Author Share Posted December 14, 2020 Thanks a lot for the clarification regarding the SSDT files. Also I see that all the patches in the ACPI section of OC are enabled. Are they all necessary for our HP model? Link to comment Share on other sites More sharing options...
