Energy driver error on Legion T5 28IMB05 and Thinkpad X1 Yoga (2nd gen) about lenovocontroller

Same error on my device: Thinkpad X1 Yoga (2nd gen)
Still anything we can do about this?

Seems like your models are missing, or have a different, energy driver:

LenovoController/source/Providers/DriverProvider.cs

Lines 18 to 19 in e3b4638

	if (fileHandle == new IntPtr(-1))
	throw new Exception("fileHandle is 0");

I can't help with support of a device that I do not own, unfortunately.

Thanks for the reply. Could you tell what do you mean by 'energy driver'? Lenovo Energy Management?
What driver your device is using?
Maybe there is still a chance to find it somewhere and make it work (at least I could try)...

Each laptop with software, that can control hardware features like power profiles, will have a driver that makes it all work. In the Legion 7's case, this driver is the Energy Driver. If you find out how your laptop operates, and you submit a PR in this repo, I am more than happy to merge it.

I just had the same issue. There was no EnergyDrv interface on my system. Looking into Device Manager I found an error on the "Lenovo ACPI-Compliant Virtual Power Controller", saying something about broken Registry settings. Possibly due to having had Vantage installed and then removing it.

The fix was to remove the device (select & DEL key), then re-detect hardware (button in toolbar) and let windows update the driver, after which the device reappeared without the error, the EnergyDrv interface showed up and LenovoController worked. Try that.
