Add support for Ideapad (and maybe Yoga)

[mooms06]

Currently the only missing feature in LenovoLegionToolkit for complete support of the Ideapad Pro 5 16APH8 is the CPU power switch, every other features are working.

I found an other open source utility on Github who have the missing feature: IdeapadToolkit.
But it need .Net 6.0, and it does not support hotkey switching, so it's not a perfect repplacement to Vantage, like LLT is.

Maybe you can join your forces to make the ultimate app, or maybe some dev can add the support to LenovoLegionToolkit with the help of the sources of IdeapadToolkit ?

As I said, the only missing features is switching the CPU power modes, I can gladly help with the tests on my own device.

As I said many times - I will not add support for Ideapads/Yoga/etc because I do not have the time or resources. If someone wants to add support, I open for it.

found an other open source utility on Github who have the missing feature: IdeapadToolkit.

Respectfully, this project has nothing that is remotely interesting, as it doesn't implement the feature, but require a DLL from Vantage to be copied. Which is neither a good solution nor it is compliant with the EULA of Lenovo's software.

Yes, I know you said that, but as it stands, LLT already almost fully supports my Ideapad, the one missing function being the TDP limit switch.
LLT could be an universal replacement for Vantage...

I'm not a dev myself, otherwise I probably would already implemented it. Speaking of which, how hard would it be ? Do we need to "spy" the communications between Vantage and the laptop to be able to replicate it in LLT ? I'm not a dev but I'm a power user, not afraid to run some command lines or such, but I need some guidance...

Thanks for your answer.
Regards.

What is needed most likely is getting Ghidra and reverse engineering the DLL that the project mentioned above uses. WMIExplorer might also be handy since most likely these power modes are changed through one of the methods on one of the WMI classes starting with LENOVO_ - they are registered under root\WMI.

[BartoszCichecki]

Another note: the other likely option is that these power modes are changed via energy driver, which will be more tricky.

[mooms06]

I'm afraid that's above my competences.

I've launched WMIExplorer and made a filter with "Lenovo", here are the results, do you think it can help ? I have no idea what I'm doing.

[BartoszCichecki]

That is the tricky part - you need to go through most of these and see if there is a method that sounds like it could be "it". Or going the Ghidra route is also an option.

IdeapadToolkit has been updated to .Net 8.0.
Coupled with LenovoLegionToolkit, it's a complete replacement to Vantage, at least on my IdeaPad.
