========================
Detailed description：
My keyboard back-light would just randomly turn off. Meaning when I press any key the light does not come on. I have to press the function key again to get it to come on. This would happen occasionally. I tried to re-install the driver for ASUS System Control Interface. I did the procedure to do EC reset by holding power for 40 seconds. I checked Windows updates and have latest version of MyASUS app installed.

Hello matt,

Does the same issue happen in Safe mode or in BIOS?

And the issue happen when the adapter is plugged in, right?

Thank you.
