[solved] MKR WiFi 1010 not executes uploaded sketch


First of all, my setup:

  • Win10
  • Arduino IDE 1.8.13
  • MKR WiFi 1010 board (WiFiNINA v 1.3.0)

I recently bought a new MKR WiFi 1010 and I'm facing an unexpected behavior.
I uploaded the "Blink" sketch successfully but when I unplug USB from my laptop and I plug it into a wall usb port (the one I use to charge my smartphone/tablet) the MKR WiFi 1010 board turns on (the power led - the green one - is on) but doesn't execute the uploaded sketch .... the led doesn't blink.
If I unplug the board from the wall usb port and plug it back again into my laptop the sketch still doesn't get executed.
After that, if I open the Serial Monitor of Arduino IDE, it starts to execute the Blink sketch.
I'm not understanding why it doesn't execute the sketch automatically but, you know, I never tried other board than Arduino UNO Rev3 and ESP8266!
What's happening?
Can you help me?
Thank you
