Schematic for the Quanta AT8 notebook mainboard, revision R1A, in a 1.03 MB PDF. Quanta, a large Taiwanese ODM, uses AT-series and similar codes for boards it builds for branded laptops. The diagram lets a technician trace the path from the DC jack through the charger to every regulator, identify missing voltages, find shorted components and check signals between chips. It opens in any PDF reader; compare the AT8 code and R1A revision on the PCB with the title block first.
