Lenovo Ideapad is supported?

[JuanH88]

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

[johnfanv2]

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:

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 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 ""
  }
