To turn LEDs off on my k6 mobo when I shut down I had to enable deep sleep in s5 in the bios. If you have not figured it out yet let me know and I will look in my bios to see what that setting wss under

Your board has dual (two) UEFI/BIOS chips, one main and one backup. That can be seen in your picture, the two chips have a sticker with the factory installed UEFI version, 1.30. That is a feature of your board, dual UEFI/BIOS.

The LED indicates which UEFI is active. It is normal for that LED to be on all the time with default UEFI settings. The LED allows you to know which UEFI chip is currently active/in use.

As said above, you can try to disable it when the PC is shutdown by setting the Chipset Configuration\Deep Sleep option to S5 from the default disabled.

We've had several threads posted recently about the UEFI/BIOS indicator LEDs on boards with dual UEFI chips. This feature has been used on quite a few ASRock boards for several years, why it suddenly seems to be an issue, I don't understand. With all the RGB lighting that is popular now, what's one more small LED on the board? Confused

on my Mobo I have to enable deep sleep 5 or all my chipset and rear io shield light plus power button and reset button on the mother board stay on plus the little bios chip light. And I don't need my computer lighting up my room when shut down so deep sleep option was the only way to let them turn off when i shut the pc down. i dont mind them at all when the pc is on.
