Yoga 3 1470 80JH Some keys not working 65-%= LCTRL

Hi, suddenly some keys stop working. 

65-%= and left control.

There was no accident or dissasembling.

Problem is also before windows starts (in BIOS).


Is it possible that one path in keyboard tape is broken and inflict on this specific keys?

USB keyboard and screen keyboard are working normally.

Hi mikolajb,


Welcome to the Community Forums.


There is probability that there is a hardware issue seing that both onscreen and external mouse would work fine. This may also be isolated by booting the machine on a different operating system like a live rescue image so it would have the same issue similar to booting in Windows.


You can review this article if the keyboard needs replacement specially if you did try to reseat the cable and cleaned up the keys:
