Or:

 

UM2407 says LD6 glows lit when an overcurrent happens (7.4.1 Power supply from ST-Link-V3E USB connector).

Do you consume too much power somewhere?

 

It is hard to tell from the 2nd pic. Is JP2 1-2 (STLINK) closed?

@mfgkw Yes it is closed sir. I haven't connected the any external device which condumes more power i have been checking the interupt pins with the weigamd readers.
