1 year ago There was another Ideapad laptop where most of the features worked. The driver definitely has to be configured and a little bit adapted. We can try but I am not sure if all features will work. Which features are the most useful for you? What is the model year of the laptop?
To this end, please provide the following information:
Model and Debug Info
Distribution: ??? (including version, e.g. Ubuntu 24.04) 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:

???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.logThen 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 DSDTThen 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 skip it. 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 ""

I know it's not very appropriate to refer to this, sorry. But I am wondering if this tool would work on other models of lenovo laptops, I am thinking of trying it on my ideapad gaming 3i
