Found "deep sleep" and enabled it. Flashing LED is gone!
BTW, my mouse light wasn't on after shutdown. I had too many computers running at once to realize the mouse was connected to another computer.]]> Thu, 06 May 2021 05:18:54 +0000 https://forum.asrock.com/forum_posts.asp?TID=18724&PID=86861&title=fatal1ty-b450-itx-blinking-power-led-while-off#86861 https://forum.asrock.com/forum_posts.asp?TID=18724&PID=86860&title=fatal1ty-b450-itx-blinking-power-led-while-off#86860 Author: TimTech

I have the B450M Pro4 and have the same problem. I ran for four months then suddenly this blinking power led manifested. I didn't update the bios or anything. Funny, just prior my bios somehow reset it's memory timing back to default by itself and I was seeing fairly regular BSOD. I did a lot of hair pulling until I found the memory timings changed. Set them back to XMP and have only had two BSOD since. I then did the load UEFI defaults thing, then XMP, and so far so good except for the blinking power LED and my mouse light still on after shutdown. I did disable "turn on onboard LED in S5" with no improvement. I haven't found any "deep sleep" setting in the bios.
Looking for a fix. I keep thinking the computer is sleeping.]]> Thu, 06 May 2021 04:50:14 +0000 https://forum.asrock.com/forum_posts.asp?TID=18724&PID=86860&title=fatal1ty-b450-itx-blinking-power-led-while-off#86860 https://forum.asrock.com/forum_posts.asp?TID=18724&PID=86714&title=fatal1ty-b450-itx-blinking-power-led-while-off#86714 Author: LilJesus
