Repl resistor ... no go.

I did short the green power supply wire to ground, and it boots. Maybe I'll just wire in a toggle and call it a day

Thanks ... gave it a go. No go.

Still no power on. I did find a resistor knocked off the board under the scope. Now looking to find a schematic ... R877, need it's value and what it is for.

As the title says ... I've seen it on some Chinese websites ... but my foreign language skills are for crap

Dell XPS 8500 / Vostro 470
DH77M01 CY0629

Dell part number 0NW73C

Board is currently getting power, but does not power on at all. Was going to try a bios if someone has a BIN dump of it. Should be 4MB I think.
