Run Nucleo only with power, no PC USB connection

Hy,
I start to work with the Nucleo Platform. I have several Nucleos and can program them with System Workbench for STM32, no problem. But when I connect the USB cable to either a USB power pack or a PC that has not installed the ST-Link drivers, my program in flash won't run.
Device is obviously powered, the red LED LD1 flashes slowly, but my program won't start.
As soon as I connect the board to a PC with the ST-Link driver installed, my program starts running again, so obviously it is still in flash.
Is this the expected behaviour? Is there anything I can do about this? I wanted to use the system for a technical demonstration but am not able to connect it to the development PC all the time.
Best regards
Harald
