Asus model N752V motherboard N752VX rev. 2.0

[valieromarco]

This laptop comes dead.
I checked PCH shorted, so after replacing it I get 3,3V 5V and other voltages except of two CPU rails as picture show.
Seems not have other shorted components.
I haven't schematic or boardviewer.
After plugged PSU motherboard turns on itself with 3 leds on.
Power consumption is 0,45A

Likely +VCC_Core Missing and +VCC_GT, what you can ignore at this Point.

I'd exclude corrupted BIOS at this Point. Is there a CMOS Battery present?

Bios flashed too.
Possible causes about missing voltages?

Missing Enable Signal, Dead VRM Controller, Dead Driver, Missing SVID communication, etc.

I have the same situation on my card, hm and I/O short-circuit both changed, I programmed kbc, but 0.35a lights are on, no processor voltages, I would appreciate if you could share your bios file
