Default Ethernet Light Always On

When I shut down my computer for some reason the ethernet light on my motherboard stays on next to the jack. When I flip the switch on my PSU it turns off after a few seconds, and when I filp it back on it stays off. Is this a problem? And if so, is it a problem with the PSU?

Is the RJ-45 cable in the socket when the light is on? Because if so it usually stays on if something is plugged in..

Default Re:


Your motherboard may still be supplying power to your ethernet adaptor because your BIOS might be set to enable boot from ethernet (network).

I'd check your BIOS settings.

i was going to say what the 2 previous posters said . it's either due to the presence of a network cable or BIOS "power-on" settings.

Okay, thanks. Next time I start my computer I will check the BIOS and report back. As long as it doesn't hurt anything I am fine with it.

It might be called Wake on LAN in the BIOS.

Yeah, those lights stay on on all motherboards. It's showing that it's powered.

Ah, you are right. I went into the BIOS and 'wake on lan' was enabled. I guess I have never noticed on other computers since most of ours have wireless.

Thanks all,
