Hello Everyone, Who can help!
So Problem is that what shows in video, basically pressing Fn(Function keys) doesn't get registered and i dont know how to fix this and also put new switch in that area and thats means thats not switch problem, maybe something work with board, and also i have this problem that after firmware update my keyboard shows on device manager unknown device. So maybe someone help me or i need to contact support. And still have warranty maybe that could help me to send them my keyboard to fix.
