So after hours research, I am finally able to solve this problem, its a simple dry joint on PL3, just removed it and resoldered it and all 3 laptops works fine now.

Hi everybody,
I have an HP DV7-3079wm with the same problem.-
Symptom: LEDs glow, fan noise is heard, but display is black and the DV7 shuts down immediately. Indistinctly if is with the battery or the power charger.-

This always occured when the notebook is turned off few time, after that won't start.

I perform a Hard reset, I take off the RAM, HD,
I look the circuit and I don't see any part of the circuit burned.

Any idea?

Just search for PL3, located around the memory and resolder it.
