Hello friends, I'm trying to change how the power button LED behaves on my motherboard or case. When my PC sleeps, it flashes a bright blue light quickly on and off to signal this. I want it to fade more smoothly or stop completely. So far, checking the UEFI settings or AURA hasn't helped. I have an ASUS ROG STRIX B650E-F and a Lian-Li O11 Air Mini.

On ASUS boards: BIOS > Advanced > Onboard Devices Configuration > LED Lighting > When system is in sleep (or similar). Usually you have limited options—just a flashing light or nothing at all. You might consider using a microcontroller to control a smooth fade via PWM, but it would be excessive for most needs.

The tiny electrolytic part near the power button should gradually shut down. It may still turn on abruptly, though.

I'd be cautious about actions that could generate more inrush current than the power LED header can handle.

Current limiting resistor should handle this, likely already integrated into the case or circuit board.
