Main board DA0N73MB6D0 REV:D
No light blinks, the fan is not spinning, on the SPI 25Q64F, no voltage.

Voltage presence LED on.

Power supply O.K.

I disconnected the battery from the bios in an attempt to reset, nothing has changed.

Looking for diagram Main board DA0N73MB6D0 REV: D.

I have a short on pin 8 of the SPI 25Q64F, towards ground I read 0 ohm. I also removed G9661, Peak 3A, Low Dropout Regulator with Enable, but the short persists. Checked and removed capacitors affected by the short, without success.
Without a scheme I see it difficult, I trust in your help. Thanks for the moment .
