DELL XPS 8500 - DH77M01 bios dump needed

[katfish]

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.

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.

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
