Nucleo-L432KC power options

another question regarding the Nucleo-L432KC board. The user manual states that it can be powered via the +5V pin or the VIN pin. However, when I want to power it via +5V, I can't get the board to run. The red power LED comes on, but visibly the code isn't executed. I have tried several different power supplies. According to the user manual I don't need to change any solder bridges either. When I connect e.g. 9V to VIN or connect it via USB it works fine. I don't have many options to debug this, since as soon as I connected it to the PC via USB it works fine.


Does anyone know what could cause this? Anyone tried powering the same board like this successfully?
