Quanta AT6 laptop motherboard schematic at revision 1A, a larger 3.19 MB PDF. The name gives only the Quanta project code and revision, not the laptop brand or board number. A technician uses it to trace power rails from the DC input onward, check enable and power-good signals, and locate the components connected to a shorted net. Quanta embeds project codes like AT6 in its DA0-prefixed mainboard numbers, so check the PCB silkscreen and revision before trusting values.
