If you feel your board is defective or has issues, request an Return Merchandise Application (RMA) by filling out the form at http://beagleboard.org/support/rma . You will need the serial number and revision of the board. The serial numbers and revisions keep moving. Different boards can have different locations depending on when they were made. The following figures show the three locations of the serial and revision number.
