No chime, black screen,
But i have green light and fan spin
System is brainless like louis says, meaning no vcore
please dont tell the direct answer, but just kick me in the right direction

Finaly vcore. Here is where the trouble should begin, according to Louis. I don’t know why lets hope I find out in the future
PPVCORE_GPU 1.11v
PPVCORE_S0_CPU 1.15v
PPVCORE_S0_AXG 0v Alarm bel....
(measured resistance but it’s the same as ppvcore_so_cpu 0.0002, but there comes 1.15v here nothing)
Oke going back to the pdf,
no stuff on R1370
no stuff on R1366
ok now I see this is out going lines not in, this means imo this only turns on after cpu turns on, damn
see attached picture for my thought on this.
Oke after going true the pdf again, I come across AXG PHASE that seems to create PPVCORE_S0_AXG
0.000v on both sides of L7550
PPVIN_S5_HS_COMPUTING_ISNS is present checked that before

Going true the pdf, I found cpuvcore enable, damn stupid.
