Quanta FM9B schematic, D3A revision, for a UMA build, meaning integrated graphics with no discrete GPU. A 091012 date code is included, and the 1.28 MB PDF names no laptop brand or model. Quanta uses short project codes like FM9B, and its mainboards carry DA0 numbers; check the code and revision printed on the PCB before relying on it. Use it to trace rails, check the charger and regulators, follow power sequencing and locate parts around a short.
