Hello,

i just received 2 units MBP 820-2915 and both have the same symptom.
Fan spins, No chime, no USB activity, No Capslock. Vcore 0.78V. when removed RAM, it beeps. same with SMC Bypass mode.
I know GPU dies alot for this modal but what are the other usual suspects?

CPU core looks good, like booted board.
I can suspect CPU gets blocked because of bad GPU.

Disable GPU and check what happens then.
