Hi,
in the morning I had a very small pulse on L7310 and L7320, but now, I checked again to confirm it and now, I don't get a pulse on them...

Can you catch any pulse at pins 7 & 3 of U1950?

 

[hgoncalves]

I get pulse on both of them

PLT_RESET_L pulsing?
Try new BIOS, just in case.

PLT_RESET_L has no pulse

Do you have a Clean BIOS for this board?

Hi,

I've tried the new BIOS but with the same result.
No power and it has green light, when conected to the bench PSU it reaches 120 mA and imedatly drops to 15 mA

"PLT_RESET_L has no pulse"
Iy stays low, or high?
