First of all, I want to say thank you for all of your hard work in order to research and share your efi build with us. I just want to ask if you know any information about my remaining issues, or lucky some solution for them.
So I have a few questions regarding other problems which I haven't resolved yet
The USB 3.0 port stopped working and the backlight flashed randomly on macintosh boot
Long sleep time and then wake will cause the built-in monitor won't turn on
Imessages doesn't work with ethernet (cause I don't have a suitable wifi card)
I wonder if you have encountered the same bugs and thanks for your support
I am using the legion-5800H with a discrete card of 3060, I adjusted some content in your efi, it works very well except for the built-in trackpad. Could you suggest a reason why this is case?
I'm just wondering how you get the "PP_PhmSoftPowerPlayTable" value.
You saved the the bios rom file using GPU-z?
I tried to save GPU bios to rom file, but failed. Someone just told me that graphics for laptops do not have standalone bios, so we can not save a rom file using GPU-z.
However, without the rom file, how could I get the "PP_PhmSoftPowerPlayTable" value?
I have the same laptop model, and I want to mention an error. When I try to install it, it shows that it's installing, but then the installation freezes and doesn't complete. The same thing happens when I try to format the partition; it freezes during the first formatting mode, but the partition gets formatted. Is there a solution?
Bro, may I take a look at your AMD Power Gadget speed steps settings? I have a laptop with the same 5600h processor, but it doesn't work when selecting different speed step with AMD Power Gadget. Do you have a customized PState?
Hi! I just wanna ask how do you determine the value of DeviceProperties containing CFG_LINKED_MAP to enable DRM on macOS.
I already installed macOS Ventura on my Legion 5 15ARH05 but the DRM fails showed by VDADecoder failed.
an answer will be highly appreciated, thank you!
The built-in microphone in my computer can be recognized normally, but when I want to use it to record sound, it doesn't respond at all.
Later, I tried to adapt to AppleALC.kext, but it still didn't work. In addition, the built-in microphone in Windows 11 can use recording to confirm that there is no problem with the hardware.
My Legion 5 is slightly different, it has the synaptics version of the trackpad. Looks like DSDT supports both the ELAN and synaptics.
Could you please send me your DSDT?
Thank you for a wonderfully successful project with your machine
I will refer to your EFI to see if I need to optimize something for my machine. And I discovered the "Delete to fix SRFZ namespace" Patch. May I know if it has any effect? It seems to me that it is not used in conjunction with any SSDT?. Can you explain to me why we use that Patch and what its effects are?
I managed to identify the internal graphics card with Nootedred, but the hdmi does not work at all. I cannot transfer images via Type-C. How can I solve this problem?
Why don't you use that kext? I have the lenovo legion 5 pro with a ryzen 7 5800h and it doesn't work for me The touchpad, the brightness control (I tried your efi and nothing...)
