Circuit schematic for Gateway MC78 and MD78 notebooks built on the Quanta AJ2 motherboard, supplied as a 1.28 MB PDF. AJ2 is the Quanta project code for this board, normally printed on the PCB together with a DA part number, so confirm it before use. The diagram lets you trace power rails from the adapter input to the CPU and memory supplies, check for shorts and locate test points and connectors. It opens in any common PDF reader, and searching for reference designators speeds up finding components.
