System: Windows 10 64bit Model: Asus ROG Strix Scar ll GL704GW Bios: 308 version ======================== Detailed description： FN+Arrow Keys no longer change the aura brightness of the keyboard even after installing ATK Package (v.184.108.40.206) and ASUS System Control Interface (v.220.127.116.11). All other hotkeys work as expected. Aura Brightness changing effects using FN + Arrow Left or FN + Arrow Right, but hotkeys FN + Arrow Up or FN + Arrow Down aren't working. Reinstalling Windows 10 and drivers didn't help. It seems that problem with bios.
