Schematic for a Packard Bell laptop built by Wistron under the ETNA project name, GM variant, saved as a PDF. The retail model and revision are not given, so match the ODM project and board markings on the PCB to the document title block before trusting part values. Wistron designed many Acer group notebooks, and its schematics typically cover the charger, power sequencing, CPU regulator, graphics and I/O. Technicians use them to locate shorted rails, find test points and follow the embedded controller power-on logic.
