Hello,
I plugged my new beagle to a 5v 2250mA adapter and the board got hot then stopped working altogether, no LEDs powering on, not even on usb power.
Is the CPU fried? Any ideas if I can do anything?
What power supply did you use? Was the polarity on the power supply correct?

Yes, I suspect the same thing,I think the power adapter was negative in the center
Had my board for 1 day, I guess it’s beyond repair 
I don’t know. I would try and get the right polarity power supply and try it. If it does not work, request an RMA and it may be able to be fixed.
