Yes, the power button is an indicator light, blue solid or flashing for asleep or awake, never seen it be orange, as said now nothing.

System was purchase direct from Dell.

I measured the voltages I did by pulling the plug and putting the probes in that end, I'll see if I can slip them down the side to get a reading while still plugged in.

The only other light on the front in normal operation is the drive light.
