HP Envy All-in-One 34" desktop won't turn on.

I have on my bench an HP Envy All-in-One 34" desktop computer that won't power on. The mode4l number printed on the bottom of the stand says, TPC-Q084-34.

My educated guess says the power supply is dead but this is not like the old ATX switching power supplies. The model number on the label says APL001.It has a 10 pin output connector which contains 1 green, 1 blue,

4 yellow, and 4 black wires. My intuition says that shorting a black wire to the green wire should turn it on (if it's working). On the other hand, I don't really want to guess what these wires do. Does anyone have any experience with these supplies? Below is a link to a photo of the connector

Thanks for your reply.
