Quanta ED3 schematic for the UMA variant, meaning integrated graphics with no discrete GPU, marked version B3B and revision A3A. The 1.02 MB PDF shows the power tree, chipset wiring, display path and connectors, which helps when tracing a dead rail, an unexplained short or a missing video signal. Because UMA and discrete-graphics versions of a Quanta project differ in layout and parts, confirm that the board has no dedicated GPU and that its revision marking matches before relying on these pages.
