Sorry I forgot to wrote these stuff. Asus b660m plus wifi d4. Rgb colors TUF rgb. I don't know if the indicators are lit or not because they are small. I woke up in the evening and he did it right then, but it has happened several times before. Exactly 1 extension cord is closed, so it is not pulled out. But the extension cord disconnects the current normally.Make and model motherboard?
What color is the light? Location?
By "unplugged"you mean that the power cord to the PSU is taken out of the wall outlet?
But it's not getting any power. I mean from CMOS battery, but nothing else, so I think it should not light up. And it's not continuous. It only flashed for a second.If this is an ASUS motherboard with various lights built in there is a setting in bios to control those lights and it needs to be set to STEALTH.
So the light only flashes when you unplug the extension cord?
Was the computer shutdown beforehand by using the Windows Shutdown menu?
The computer should not be being shutdown by unplugging the extension cord or using some switch in the power connections to the PSU.

This motherboard?
Asus b660m
Verify that I found the applicable User Guide.
Use the Motherboard Overview on Page 1-1 to identify the LED that flashes when the extension cord is unplugged.
I believe that you may be referring to the System Power LED as mentioned at the top of Page 1-5. Is that correct?
If not please identify the LED that flashes.
Capacitors can hold charge very long time, potentially indefinitely. MB has a lot of them but PSU has very large and of high capacity. One way to discharge them is to push start button after disconnected from main power.I don't know, but as you wrote, all the LEDs light up during boot. I think this is because I disabled fast boot and everything
check taste.
I see that the 16 is connected. As you said, when it is turned on, it lights up continuously, but something else also flashes on the header panel. But it's not about those.
Also today, the TUF logo flashed for a second at about 3 a.m. But he can do this several times in one night, I don't know. I am attaching which light I see flashing all the time. But unfortunately, I only saw the light of this one, and as a result, I don't see the light of other LEDs. By the time I look over, the light has already gone out. I know that in this case it has to be constantly lit and that is not the problem.
