Recently i replaced the motherboard of an Asus Q504UAK (i5-7200u), now the keyboard light won't turn on, ATK driver installed, Fn +F3-F4 won't work, i tried Gary Fix (Bt.exe) but it returns: "NO SUPPORT EXTF FUNCTION!", I used a CH341 to flash the original Bios Dump from the damaged motherboard, but it didn't work too.
