NUCLE0 L073RZ board heating up

I am seeing a problem with couple of my Nucleo L073RZ REV C boards which starts to heat up when powered using VIN i.e 12V supply. The boards are working fine, but I can feel the temperature increase if I touch the backside of R29/R30 resistors.

If the board is powered through USB or even if USB cable is connected (powered using VIN) I don't see the temperature rise. Anyone know the reason for the same.

Thanks Hemanth
