Librem 15 version 3 won't turn on

Hi, my Librem 15 suddenly shut off and won’t turn back on, I disconnected the battery and pressed the power button for a minute and plugged it in with the battery disconnected, but still nothing! Can anyone help me with this situation?

Is there orange LED lit when you plug in your charger? If not, could you check if the charger is okay (try it with another laptop, or measure its output voltage or try another charger with your Librem).
