I have recently received a Ducky mecha sf radiant emerald. They keyboard is great but when putting the PC to sleep or shutting off, the lights on the board stay on. Is this normal for these boards? My last mechanical keyboard would shut it's lights off when the PC was either asleep or shut down. I know you can disable usb power in bios, but I do like to be able to charge my headset while the pc is off or sleeping.
