Turn off leds when PC is off

Hi tattdogg,

Thank you for your test and reply.

Please update the BIOS L1.61 and check the result. This BIOS should help you fully disabled the onboard LED when the system is off.

After the BIOS update, please make sure the "Turn on onboard LED in S5" is disabled. You can find this option under BIOS\Advanced\Chipset Configuration

Hi ASRock_TSD,
I had this option disabled in BIOS and everything worked fine (Z490 Extreme4)
But then I accidentally installed beta version of ASRock Polychrome RGB app
After that LEDs are always ON.
I tried to re-disable BIOS option, uninstall beta and install stable version of Polychrome RGB app
Nothing haven't helped
Looks like beta app had updated LED controller firmware (not sure about that)
How can I fix that?

Thanks

Hello everyone. I have a Z390 Extreme4. How can I make the LEDs go off when the PC is off? Thanks!
