Jetson Nano doesn't open

My Jetson nano was working today morning but now won’t turn on. I’ve tried running it with both barrel jack and usb but neither is working. The power led does not turn on at all, but the ethernet leds are on even though I do not connect an ethernet cable. Also, when I try to powering the board, it does not turn on, but the fan on it works.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

hello e180504009,

please setup serial console though UART to gather bootloader messages for reference,
