Reset OS: no
========================
Detailed description：
The backlight stopped working and it's adjustable from the keyboard like: FN+F3 and FN+F4. It's very nice to have in a dark rooms.
I read that one can reinstall the Asus driver Asus ATK_Package_V100061 witch controls this and I did, but all other FN command but not the backlight works, like FN+F5 för screen light and FN+12 for music volume so my question is, is the keyboard then (hardware) broken? I opened the laptop and the cable is attached correctly to the keyboard.
There are two cables one large for normal operation and one small for this backlight.
Any idea what to to?
Is there some more Software settings I can toggle to get this working?
Bios settings?

Hello erik,
Please enter BIOS or safe mode to see if the backlight works,
if not, it is very likely a hardware issue.
Please kindly send the device to our service center.
Thank you.

Thanks I opened Bios on start with F2 and I also started win10 in safe mode but backlight is not working.
It's a 4 year old laptop. Do I need to buy a complete new keyboard part or is there some smaller part needed to be replased?

Hello erik,
I can not guarantee at this moment.
Maybe only the cables are not working well, maybe the whole keyboard need to be replaced.
Service center will examine the laptop first, and let you know what need to be repaired or replaced,
then you can decide if you want to repair it.
Thank you.
