Dead HP All-in-one

This morning, as she was working on her HP 100-5050 all-in-one, it died. Black screen, no fan or HD noises. Nothing. The power brick is outputting over 19V unloaded.

Does this sound like a motherboard failure?

Resolution: the UPS failed! Unfortunately, the only thing plugged in to the UPS was the computer!!!

Sounds more like the power supply blew out, I'd suggest contacting HP to see what they can do as far as providing a replacement.

I thought that all-in-ones didn't have power supplies like conventional desktops and used the external "brick" as the power supply.

I think G-Unit is referring to the power distribution within the computer which usually consists of DC/DC converter(s), Power Control Logic chip(s) and voltage regulator(s)

But that does not sound like it would be an easy job replacing any of those!

On some units the power distribution is on a daughter board which is fairly easy to swap but that is not the case (that I can find reference to) in your system - if the power distribution, you'd be looking at replacing the motherboard

Even if they don't have PSUs, everything still has a power supply that it draws power from - that includes laptops and all in one PCs.
