Circuit schematic for the Quanta ED2 board in its UMA configuration, where graphics come from the chipset or CPU rather than a separate GPU. Version 1C, revision C2A, supplied as a PDF of about 1007 KB. A technician uses it to follow voltage regulators, power-good chains and signal routing between the chipset, memory and I/O while diagnosing power or boot faults. Quanta builds separate discrete-graphics variants of many projects, so check the PCB revision and graphics setup first.
