Intel NUC Mini PC's motherboard light doesn't light up

TechGeek-DA — Wed, 25 Jun 2025 10:13:41 GMT

I have an Intel NUC5CPYH Mini PC, and when I connect the PSU to the motherboard, the green light on the motherboard doesn't turn on.

The PC also fails to power on after pressing the power button.

I checked the output voltage of the PSU and it's 19V.

I tried BIOS reset, but that doesn't work either.

Why is the green light not turning on after connecting the PSU?

I'm recommending you test with another PSU

Yes, I tried with another PSU, but that didn't work either. I already mentioned that I checked the voltage of the PSU, and it was fine, so there is no point in changing the PSU.

I think the power chip on the motherboard is gone.
