If you have a model with a light at the IO-ports at the back, a light in the Y-Logo in the lid, or another light in the lid please help to test this feature. Please provide the following information. It must be tested on multiple different models since I assume they have slightly different methods. I will first gather information from different models (see below), then implement it, and then ask you to test if it works.

Model and Debug Info

Model name: ??? CPU model: ??? (e.g. AMD Ryzen 7 5800H) GPU model: ??? (e.g NVIDIA RTX 3700) Keyboard backlight: ??? (RGB, single color with off/on, single color with off/medium/bright) Light in lid or logo: ??? (yes/no) Light at IO-Ports at back: ??? (yes/no)

Output of sudo dmidecode -t system. Please remove Serial Number and UUID for privacy:

???

Output of sudo dmidecode -t bios:

???

Test reading light state

Please pull the newest code, compile, and load the kernel module as described in the README, i.e. until the step sudo make reloadmodule.

IO-Port light

The light at the IO-ports can be turned on/off by pressing Fn+U (maybe other?).

Turn the light off.
Get output of sudo cat /sys/kernel/debug/legion/fancurve and copy here.
Get output of cat /sys/class/leds/platform\:\:ioport/brightness and copy here.
Turn the light on.
Get output of sudo cat /sys/kernel/debug/legion/fancurve and copy here.
Get output of cat /sys/class/leds/platform\:\:ioport/brightness and copy here.

Y-Logo/Lid light

The light can be turned on/off by pressing Fn+L (maybe other?).

Turn the light off
Get output of sudo cat /sys/kernel/debug/legion/fancurve and copy here.
Get output of cat /sys/class/leds/platform\:\:ylogo/brightness and copy here,
Turn the light on
Get output of sudo cat /sys/kernel/debug/legion/fancurve and copy here.
Gett output of cat /sys/class/leds/platform\:\:ylogo/brightness and copy here,

The following information would be useful but are optional

Inspecting WMI entries

# Install required tools
sudo apt install fwts

# Create folder for all the new files
mkdir fwts_re
cd fwts_re
sudo fwts wmi - > fwts_wmi.log

Then upload files.

Disassembling ACPI tables

# Install requiered tools
sudo apt install acpica-tools

# Create folder for all the new files
mkdir acpi_re
cd acpi_re

# List ACPI tables and copy them
ls /sys/firmware/acpi/tables/
sudo cp --no-preserve=mode /sys/firmware/acpi/tables/*SDT* .

# Disassemble tables to output DSDT.dsl
iasl -e SSDT* -d DSDT

Then upload files.

Gathering WMI info in Windows

If you have Windows, then the following information are very very useful to make use of the ACPI methods. If you do not have Windows, then just skip this. Open powershell as admin in Windows and run the following script. It will list all available lenovo WMI methods. Copy output to a file and upload.

$wmi_classes = Get-WmiObject -Namespace 'ROOT/WMI' -List -Class "*LENOVO*"
foreach ($wmi_class in $wmi_classes){
  Write-Host "########################################"
  Write-Host "########################################"
  Write-Host "########################################"
  Write-Host "Name:" $wmi_class.Name
  Write-Host "Class Name:" $wmi_class.Name 
  Write-Host "Class GUID:" $wmi_class.Qualifiers["guid"].Value
  Write-Host "Description:" $wmi_class.Methods.Count
  Write-Host "Methods:"
  foreach ($method in $wmi_class.Methods){
    Write-Host "Name:" $method.Name
    Write-Host "WmiMethodId:" $method.Qualifiers["WmiMethodId"].Value
    Write-Host "Class Name:" $wmi_class.Name 
    Write-Host "Class GUID:" $wmi_class.Qualifiers["guid"].Value
    Write-Host "Description:" $method.Qualifiers["Description"].Value
    Write-Host "Implemented:" $method.Qualifiers["Implemented"].Value
    Write-Host ""
  }

IMG_20230504_234219 Are you looking for this?

Lenovo Legion Y7000 (china version) Intel i7-8750H + Nvidia 1050ti

May 04 '23 15:05 Guanran928

@Guanran928 Yes, but I am not sure if it will work on this older model. It would be great if you can do the tests.

May 04 '23 16:05 johnfanv2

Oops. I think disabling Y-logo light feature isn't available for my model, but here's my system information anyway

May 05 '23 04:05 Guanran928

@Guanran928 Sorry, I forgot to mention that you also have to pull and load the kernel module (see above and README) before it might work :smiley: . Could you please upload the file output1.txt and output2.txt ? I guess I have to add your model to the kernel module before it work and I need this information to do it.

May 05 '23 09:05 johnfanv2

Here you go :D.

output1.txt output2.txt

May 07 '23 14:05 Guanran928

Also, the command sudo make reloadmodule isn't working for me. (I did not notice that before, sorry 😟) The log says: [ 648.065732] legion PNP0C09:00: Module not useable for this laptop because it is not in allowlist. Notify maintainer if you want to add your device or force load with param force. Currently I have no idea how to force load XD

Full log here: 1.txt

May 07 '23 15:05 Guanran928

Thanks a lot for the logs. You can force loading it with sudo make forcereloadmodule.

May 07 '23 15:05 johnfanv2

Looks like it is still not working with sudo make forcereloadmodule

Here is the log with sudo make forcereloadmodule > 2.txt 2.txt

May 07 '23 15:05 Guanran928

@Guanran928 I added your model/BIOS version to the the code. You can try it now by getting the new code (git pull or just downloading again), compiling again (make), and loading again (make reloadmodule) it should now work without forcing.

May 07 '23 15:05 johnfanv2

sudo make reloadmodule worked, but FN+L didn't work for me, after some researching, I found that disabling Y-Logo light is not a thing on my model with this specific GPU (according to Lenovo), I didn't know this and I am really sorry. I apologize for the effort that you spent. Is there anything else I can provide?

May 07 '23 16:05 Guanran928

@Guanran928 Thanks for the feedback on controlling the light!

If you want, you can test if the other features, e.g. in the python GUI, work on your laptop in Linux. If something does not work, then feel free to report back I can try to adapt the software to make it work with your model.

Have you tried compiling the latest version of the module from git?

Jun 08 '23 16:06 XenHat

@XenHat I followed instructions from README. Latest commit in local directory matches current latest: https://github.com/johnfanv2/LenovoLegionLinux/commit/f3f363fc1c24469dfc7683003b9ba91dec38f5af

It's been a while, so I removed old directory, updated the system, rebooted and repeated steps:

/sys/class/leds/ before sudo make reloadmodule

input2::capslock/   input2::scrolllock/ input3::compose/    input3::numlock/    input6::capslock/   input6::kana/       input6::scrolllock/
input2::numlock/    input3::capslock/   input3::kana/       input3::scrolllock/ input6::compose/    input6::numlock/

/sys/class/leds/ after sudo make reloadmodule

input2::capslock/        input3::capslock/        input3::numlock/         input6::compose/         input6::scrolllock/      
input2::numlock/         input3::compose/         input3::scrolllock/      input6::kana/            platform::kbd_backlight/ 
input2::scrolllock/      input3::kana/            input6::capslock/        input6::numlock/         platform::ylogo/

platform::ioport/brightness is still missing.

Perhaps the instruction/code isn't adjusted to my model. It has toggle backlight for ports on the back, but no "Y-Logo" - instead it's "LEGION" text logo with RGB backlight.

@sakgoyal Can you somehow control the light of the logo in the lid, e.g. with Ctrl+U or Ctrl+Y? Otherwise, I think controlling the lights in the logo is not possible.

Jul 14 '23 19:07 johnfanv2

I was not able to control it no matter what. I tried Fn+{all letters}. I just want to be able to control the fan behavior (Fn+Q). I am ok with the light staying on. I am also able to manually control the conservation mode for the battery using this command when inside sudo su: echo 1 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004\:00/conservation_mode I didnt know this model even supported that option until I tried it. I never saw that option in vantage when I was on windows. maybe this other folder can do something or has some information that can help?

Jul 14 '23 20:07 sakgoyal

@sakgoyal Then I guess it is not possible to control the lights by software when it is not possible to control it by some key combo.

I see that you use a older model. I have to add it to the kernel driver module. Please create a new issue, where we can test it and try to test all the features step-by-step. Then we can try to fix all stuff (fan control, power modes,...).

I guess this is the same laptop as in previous post from @themightymak the other thread... According to your instructions, I moved my to this thread. Sorry for the inconvenience.
Either way, I am posting more data @johnfanv2 EDIT: @johnfanv2 - Updated WMI Info from Windows 11 (no significant difference): win10_11_wmi_info.diff.txt

Please let me know how you would like me to test it and where and how you would like me to post the results and logs and eventual bugs or issue for further development for this laptop.

Thank You so much for all your effort!

@linuxazo Did I understand that correctly that you can control the light at the IO-Ports and the light in the logo with the keys Fn+U and Fn+L? This is interesting because I want to get this into the driver and software but I cannot control it on my own model. I will look at the ACPI dissambly and try to find a way to control it on the newer models. Currently, you logs looks like it does not work. Stay tuned!

@johnfanv2 Yes. You understood correctly. I can control those lights with those keyboard shortcuts without issues.
