Re: HP 820 G3, Power Flashing.

If it was good before flashing the BIOS, chances are it's the wrong image or it's corrupt.

"HP 820 G3", and only that, doesn't really tell us anything. Theres an i3, i5, i7 or even an AMD board, each with different BIOS. And different revisions for each that could have yet a different BIOS. Need to be more specific. For example:

I have the board 831762-001 from an HP 820 G3, i5-6200U, and flashed this file with MD5 cb229e609f1ebd3d56e4da05cc2f6645.

With the provided information we can't even know which are the schematics you need
