Nvidia Jetson Nano not booting up

I have an Nvidia Jetson Nano model p3450 that will not turn on, the power led does not come on at all. I have confirmed I am supplying 5V with 4A through the barrel jack, and I have the jumper to disable uUSB installed. Am I missing something? What’s going on?

Hi,

Could Jetson nano enter into the recovery mode?

Please try to put it into recovery mode and run lsusb to check.

Thanks
