Perhaps the LED stays on without PSU power (CMOS battery status LED)?

This is a relatively big channel. It's unlikely they they would make such a mistake.

    I guess anything is possible, but I don't think I've ever seen a CMOS battery light, though I've seen a lot of motherboards with an LED to indicate that they're getting power from the PSU. I'm pretty sure that you'd burn through a CMOS battery pretty quickly if you just left an LED always on powered off it.
