2019-10-11, 13:31 PM

I just bought a laptop legion y540. Then, i have been installed full driver for my y540.

But, when I check, laptop can't use fn with f4, f8 and f10.

How to solve this issue?

Thank you very much!

Same here. It seems Lenovo's own drivers bug. Please fix it.

But this Lenovo Utility doesn't show anything if I do Fn + Q. I have to open the vantage app to actually see the changed thermal mode
