Jetson Orin Nano Developer Kit Won't Power up

Hello, i’ve bought a new one Jetson Orin Nano Developer Kit Product code 945-13766-0000-000.

It won’t turn on. I tried with the power supply that came in the box. I tried with USB C using a 5V and 3A output power supply. I tested the standard 19V DC power supply, but no LED lights up and the cooling fan doesn’t even spin. It seems dead.

OK, I solved the problem by changing the power supply cable to the mains. Now it’s turned on. Thank you.
