I don't know which interface these controls are using, so I will be needed some help to add this toggle.

Just out of curiosity, can you use the Fn+U or Fn+L shortcut to turn these on/off?

[AceAsket]

yes FN + U worked

will this be added to the plan?

[BartoszCichecki]

If someone reverse engineers, how are they controlled then yes.

Hi @BartoszCichecki, you may implement that by using this script.

function Toggle-RearUSBLightingState {
    $LenovoWMIPath=(Get-WmiObject -Namespace "root\WMI" -Query "SELECT * FROM LENOVO_LIGHTING_METHOD").__PATH
    $LenovoWMI=[WMI]$LenovoWMIPath
    $LightingID=5
    $CurrentState=$LenovoWMI.Get_Lighting_Current_Status($LightingID).Current_State_Type
    $TargetState=[int]($CurrentState -xor 1)
    $LenovoWMI.Set_Lighting_Current_Status($LightingID,$TargetState,0)
    
}

function Toggle-LogoLightingState {
    $LenovoWMIPath=(Get-WmiObject -Namespace "root\WMI" -Query "SELECT * FROM LENOVO_LIGHTING_METHOD").__PATH
    $LenovoWMI=[WMI]$LenovoWMIPath
    $LightingID=3
    $CurrentState=$LenovoWMI.Get_Lighting_Current_Status($LightingID).Current_State_Type
    $TargetState=[int]($CurrentState -xor 1)
    $LenovoWMI.Set_Lighting_Current_Status($LightingID,$TargetState,0)
    
}

@RoadToDream do you know if more could be done via this interface? Anything more than USB ports and logo lights?

[RoadToDream]

There should be more for different versions of BIOS, but for mine I guess that's all. There are also some methods that helps implementing Spectrum via other interface. But that is not related to this issue.

[BartoszCichecki]

Hey, @RoadToDream you have an idea how to check for compatibility of this feature? I can execute these commands on L5P which doesn't have backlight of ports. I need to check somehow if device supports it, so that I don't show this on device like L5P.

WMI call should return a code where code 3 should be error. If that doesn't work, maybe a BIOS version whitelist is good I guess.

[BartoszCichecki]

Closing since there doesn't seem to be a consistent interface for this that would allow:

1. Checking if devices has support for this
2. How to reliably turn it on/off an a wide range of devices.

In general looks like Lenovo has a very complex/broken logic for this.

If someone comes up with a solution to this make a PR.
