Schematic for the Flex H510UA1 board, revision RD, in a 3.09 MB PDF. Flex (Flextronics) produces boards for other companies, so the end-product brand is not stated and should be confirmed from labels on the hardware. The larger size suggests a fairly complete set of pages. Use it to trace voltage rails, follow enable and power-good signals and pinpoint test points when diagnosing a dead or shorted board. Make sure the code and revision RD on the PCB match before trusting component values or locations.
