Hi all,

I have an AsRock B450M Steel Legend (the pink one). I've had this PC for 6 months. The LEDs not turning off when I shut down always annoyed me, but it was just this week when I learned that disabling LED in S5 under BIOS is possible. And so I did.

It worked for a good 3 days, but today the LEDs did not close upon shut down. I double checked BIOS and it was still disabled.

Do you know any quick fix? I mean - I guess I can live with it but I really hate having lights when I sleep :) I don't like flipping the PSU switch off (just to turn off the LEDs) and I just leave my PC connected to the UPS even when it's shut down.

Many thanks for all your help for this newbie!
