You need to provide more information.

1. Logs from current version
2. What type of keyboard backlight is it (white/per-key rgb/4-zone rgb)?
3. How many backlight levels are there?
4. What are the current keyboard shortcuts to control the keyboard?
5. Screen shots of all backlight settings in Legion Zone or Vantage

[pengweiqhca]

1. Who's log? LLT(folder is empty) or legion zone?
2. white/per-key
3. three: 0% 50% 100%
4. Not found shortcut.
5. Legion Zone(Vantage not test).

ps: I am a C# developer, I can assist you debuging.

Also,

white/per-key

You mean it's white only or you can set each key color separately?

[pengweiqhca]

Sorry, I misunderstand, Is single color, not per-key.

OK so the place you want to debug is here:

https://github.com/BartoszCichecki/LenovoLegionToolkit/blob/68f341e255d4874cf3461e8c16d14c8d0d3e581f/LenovoLegionToolkit.Lib/Features/WhiteKeyboardBacklightFeature.cs#L15

Please check what value do you have in outBuffer on line 17 (or if you get an exception). It might be that Lenovo either uses a different result code or they changed the interface completely.

[pengweiqhca]

Exception in https://github.com/BartoszCichecki/LenovoLegionToolkit/blob/master/LenovoLegionToolkit.Lib/Features/AbstractDriverFeature.cs#L83.

It looks like there is again another method for controlling the backlight unfortunately.

I will need to do some reverse engineering so it will probably take some time.

Legion Slim 7 16IRH8 (BIOS M0CN27WW) also cannot change change keyboard backlight with FN + Backspace

@pengweiqhca Hey, could you try version 2.14.1, and run SpectrumTester.exe? I would like to see what kind of keyboard do you have. It will also try to adjust brightness as a test to see if the keyboard is responding.

Not relevant anymore for now.

[BartoszCichecki]

I would also appreciate output of this PS command: Get-WmiObject -namespace root\WMI -class LENOVO_LIGHTING_DATA

[BartoszCichecki]

And one last thing: can you test this build? LenovoLegionToolkitSetup.zip

[pengweiqhca]

Sorry, I has sold it for other reasons, I can't test.

[BartoszCichecki]

That's ok, I managed to find someone with 2023 Slim 7 who did some tests and I think it's ok to assume that this will be solved for 2023 7 Pro too.
