HP Compaq nc6230 business notebook schematic, a 1.36 MB PDF. The name states only the brand and model, giving no motherboard number, ODM project code or revision, so compare the board markings with the title block inside the document before using its part references. HP business laptops of this period were usually built by ODMs, and the schematic page headers often show the original project code. Open it in any PDF reader to trace the charging and power circuits, follow signals and find the components to check when the machine stays dead or shows no image.
