My board is B250M Pro4.

Is there a way in the settings somewhere to change the power LED behavior in sleep mode?  That blinking light drives me nuts at night.  I'm considering just unplugging the power LED at the board but would like it to work when not in sleep mode.

The blinking power LED is a standard thing in Sleep mode for PCs. Some boards have a BIOS option called Good Night LED, in the Chipset Configuration or Tools screen, that when enabled would turn off the Power and Keyboard LEDs when in Sleep mode. I don't see that setting in your board's manual, but it might have been added with a later BIOS update.

Otherwise, find a piece of thick, opaque tape to put over that LED at night, or something else to cover it.

Hi Parsec

I have X570 Steel Legend

https://www.asrock.com/MB/AMD/X570%20Steel%20Legend/

In BIOS/UEFI menu I have option "disable power led on S5" but not working good. On both switches (disable and enabled) on suspend (linux command pm-suspend) where computer go to sleep (with enabled WOL because computer work as NAS) power led is blinking.

In night is frustrating.

Can Asrock fix it?

BR, Krzysiek

Can't edit

BWT - disable "power on on keybord " not working in suspend mode. Every toutch keyboard wake up the computer.

Have UEFI 1.6, newest is 1.92 but change log not say about this two issues however tommorow will upgrade BIOS and check.

I painted the flashing LED with a blue alcohol marker and it's calm ..
