Buenos días, cuando enciendo mi Mavic 2 Pro, el cardán realiza los movimientos característicos, pero no el sonido cuando se enciende y las luces no se encienden, ¿alguien sabría cómo decirme el problema? Gracias.

Sorry for the difficulties with the drone, the battery info doesn't show either, did you try with another battery? Was the drone crashed or encountered any hard landing? How did you power on the drone? Any chance to share us a short video of the problem?

Hi Mindy. He never had a forced landing, because only once could I lift him to 1.3 meters. to make the test flight, then I downloaded it, and the next day I tried to do the same, it asked me to calibrate the IMU, I did it and after that the problem arose.
and it does not allow me to calibrate the imu anymore because it indicates that the aircraft is disconnected.
Could you please help me?

test if with another battery, and it's the same

Could you tell me how to upload a video because it does not allow me.
tells me that only photography formats are allowed
