PDF schematic, 2.03 MB, for the Quanta ZB2 notebook motherboard. No revision or end-product model is stated in the name. Quanta designs and builds boards for several laptop brands under internal project codes such as ZB2, so the code printed on the PCB is the reliable way to match the document. Use it to follow the power sequence from the adapter input to the CPU core rails, to locate the circuit behind a short to ground and to read pinouts of connectors and controllers. Check the revision on the board before trusting part values.
