Lenovo Yoga C940 Unknown device ACPI

2021-01-13, 21:33 PM

I just bought this laptop model 81Q9 and there is an x on my device manager that I wanted to solve. The detail said it's related to ACPI\YMC2017\0.  Which driver should I download to resolve this issue?

Welcome to the community.

 

Based on ACPI\YMC2017\0, it *may* be related to the Yoga Mode Control application. If you visit your support page's driver listing and select Software and Utilities:

https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/yoga-series/yoga-c940-14iil/81q9/downloads/driver-list/ there is a YMC package available.

 

HTH a bit.

Regards.
