Hello yoonlim,
Please kindly send the device to service center to check for the hardware.
Thank you.

And i found out restarting the ASUS Optimization service or toggle F7 will bring back the backlight. I think it is related to driver/software issues rather than hardware issues.

Hello yoonlim,
Well...that's special since it was not working in safe mode, I will keep record of it.
But anyway, glad that you found the solution.
Thank you for the update.
