Schematic diagram of the Quanta BL6 notebook motherboard, 5.02 MB PDF. The name carries just the Quanta project code, with no revision, brand or model indicated. Quanta manufactures laptops for numerous brands and marks each board design with a code like BL6. The document serves for tracing power rails from the DC jack onward, checking the charger and voltage regulator circuits and following signals between chips. Compare the code and revision on the PCB with the title block first, since differing revisions may use other parts.
