Lenovo Y540 Keyboard problem

I have an Y540 and sometimes, randomly they Keyboard is unresponsive after awaking from sleep on windows 10.


I have to use the Windows 10 screen accessibility keyboard feature to input the password with mouse and after logged in the keyboard works as expected.


Do anyone has this problem?

Re: Lenovo Y540 Keyboard problem

Happened to me a couple of times, but I think using a shortcut (fn+f#) made my keyboard work again.
