Sony laptop schematic in PDF form for the Quanta-made motherboard DA0HK9MB6D0, revision 1A. The DA0...MB6... numbering is Quanta's pattern, meaning the board was designed and produced by Quanta for Sony, with HK9 being the project code. The diagram is used to trace power rails, check the power-on sequence, identify the charger and PWM controllers and look up component values. Compare the board number and revision on the PCB with this document first, because Quanta often reissues boards with altered circuitry between revisions.
