Quanta EL8 schematic diagram, board revision 1A, a 1.22 MB PDF. It documents the motherboard circuitry, including power-supply stages, the embedded controller area, chipset links and connectors, which is what you need when chasing a no-power, no-charge or no-display fault. Quanta names its laptop designs with these short project codes, and many brands sell the resulting machines. Read the project code and revision on the PCB before you start, because values and placement can differ between revisions of the same design.
