I installed a new Asus z170-e motherboard today and it has a white light under the back edge of the motherboard that flashes constantly on and off about once per second or so. I don't see it in the manual. I'm just wondering what it is. The motherboard presently seems to work fine, in spite of that light, and isn't showing any of the problem lights.

That would appear to be the Audio LED Lighting:
These LEDs light up when the system is fully powered and operating. To change the behavior of the LEDs to still mode or breathing mode, refer to BIOS section 2.6.8 Onboard Devices Configuration Audio LED Lighting for details

3My impression is that it indicates the power supply is connected. But it seems strange to me, that such a bright and slowly flashing light would be used for that kind of indication. And it seems strange that I can't find it in the manual. Note that it happens even when the PC power is off, as long as the power supply itself has power. Also, it's a different kind of light than the problem lights. it's brighter, and white. They're dimmer and colored. They're on top of the motherboard. It's on the bottom.
