Quanta schematic covering the LZ3 and LZ3A boards at revision 1A, dated 2011-12-01 in the name, as a 1.65 MB PDF. It gives the full circuit diagram: power sequencing, voltage regulators, charger, clock and data buses. Any PDF viewer opens it, and searching for net names speeds up tracing. No laptop brand is stated, so confirm that the LZ3 or LZ3A marking and the revision on the PCB match. Pair it with a boardview to locate the components physically when diagnosing a no-power or short-circuit fault.
