hi there! it's not an issue

[Vorshim92]

Hello! :) I'm also a happy owner of this laptop. If you want a hand in improving some features, I can give you some advice. I have working Thunderbolt, applied LayoutID 69 on the latest AppleALC with a functioning combojack (headphone mic as well). I'm working on a solution for S3/S4 hibernation mode 3. I noticed that you use an SSDT; in reality, it should be sufficient to disable a function in the BIOS called "Low Power S0 Idle Capability" with a tool called ru.efi (or maybe with setup_var Setup 0x20 0x0). Anyway, I'm finishing up my GitHub repository, so in case, you'll be able to see everything better there ;)

Hi there,
Thanks for sharing!

I wasn't aware of the ru.efi tool which was why I instead used an SSDT to disable S3. Everything else sounds great!

Please keep me updated, thanks!

setup_var Setup 0x20 0x0

yeah! you can also use the same tool for the CFG just using this
setup_var Setup 0x20 0x0
are you using last bios? 1.26?

bios 1.26 xps 2in1 7390.txt
here the txt of our 1.26 bios
you can also check DVMT option for the igpu so can avoid to use speacial fix in the Device Prop...
I use ru.efi, which is much simpler and faster and less dangerous than it seems, but I believe it can always be done with that CFG tool.

DVMT Pre-Allocated is in SaSetup

setup_var SaSetup 0xA4 0x5
to set it to 160MB

DVMT Total Gfx Mem
setup_var SaSetup 0xA5 0x3
to set it to MAX

try this :)

and from the last applealc dont' forget to set layoutid 69

Thanks, I'll make sure to add them to the repo.

Where'd you get ru.efi from? I have never seen that tool in all my research.

What issues were caused by the DVMT and what's the special fix? I didn't have any issues with my iGPU, so just curious.

RU.EFI is a tool from JamesAmiTw -> https://github.com/JamesAmiTw/ru-uefi
this is an example from one of my laptop -> https://github.com/Vorshim92/HP-Pavilion-x360-14-dw0004nl-Ice-Lake#bios-settings-for-bios-version-f21
it's a good tool! let me know if you reach the same result with the cfg tool with the commands I wrote you in the last message.

anyway

this is the fix you have in your config. with that change in bios you can delete it.

this is my patch btw.

can I ask you if you have touchscreen and trackpad working?
if you want to share information better with me I have telegram here: Telegram

I will add these bits of info to my repo. I am (and have been) quite busy lately, I will add them whenever I have time.

Thanks again!
