Circuit schematic for the Quanta GC3A notebook motherboard, a 4.02 MB PDF. Only the Quanta project code appears in the name, so the revision and the laptop model are not stated. Quanta, an ODM for many notebook brands, marks its boards with such codes on the silkscreen. A technician would use this document to follow power delivery from the charger to the CPU and memory regulators, check signal connections and locate parts. Before relying on it, read the code and revision printed on the PCB and compare them with the document title block.
