Only your solution has solved the keyboard backlight problem for my Samsung Series 9 laptop. For me at first it was an issue to find Samsung Settings App and Samsung Update tool, since in the official download page of Samsung Support there was no any of these items. GeForce® GTX 1080 Ti is the fastest gaming GPU that delivers 35% faster performance than the GeForce GTX 1080.

After you upgrade your computer to Windows 10, if your ASUS Mouse / Keyboard Drivers are not working, you can fix the problem by updating the drivers. It is possible that your Mouse / Keyboard driver is not compatible with the newer version of Windows.

Option 1 (Recommended): Update drivers automatically - Novice computer users can update drivers using trusted software in just a few mouse clicks. Automatic driver updates are fast, efficient and elimate all the guesswork. Your old drivers can even be backed up and restored in case any problems occur.

OR

Option 2: Update drivers manually - Find the correct driver for your Mouse / Keyboard and operating system, then install it by following the step by step instructions below. You’ll need some computer skills to use this method.

The laptop is ASUS FX503vd, I tried several versions of Linux kernels (currently running one is the 4.17.1), but still have not managed to make the keyboard backlight control keys work. After the system boot on, the backlight is always on. There are two function keys (reused the numerical keypad) which is to control the brightness of the backlight. In windows, I can adjust down its brightness until fully off. But pressing the same keys in Linux has no effect at all. My feeling is the kernel did not detected the corresponding WMI device

Below is the /sys/devices/platform/asus-nb-wmi/ contents:

Does anyone have some clues about the laptop keyboard issue?

Does the driver depend on the layout of the keyboard?

Thanks in advance.-woody
