Do you have a BIOS dump for this board maybe?

DUMP dell latitude e5450

Hello.

I'm trying to toubleshoot a Dell Latitude E5450 that, at first, did not have any sign of life.
Charger would go into protection mode and I was able to find a bad cap (PC717 in the boardview file attached). I removed it and now I have a white light on power button, but it turns on and off, after about 15 seconds.
I can find 19V, 5V and 3.3V coils but I could not find 3.3V in the BIOS chip (this model has just one).
In the schematic (also attached) I can see the BIOS is component UC2 and 3.3V should come from +3.3V_SPI. Is that right?

...

Please help repair BIOS. All power rails are OK but no display.
No EC BIOS chip UC3
