Schematic in PDF form for the Quanta N91C notebook board, revision C3A, compressed into an 805 KB RAR archive. Quanta is a laptop ODM, and N91C is its internal project code, so the same design may appear under different retail brands. The circuit diagram is used to trace power rails, check the power-on sequence, identify the correct value of a burnt component and follow signals between chips. Compare the revision on the PCB with C3A, since component values and circuits can change between revisions.
