Schematic PDF of about 990 KB with a generic messaging-app style filename that gives no model information, though board number 6050A2364601 has been identified for it. That pattern is the Inventec numbering, common on HP notebooks. Use the diagram to follow power sequencing, locate the faulty rail and check signal connections around a dead board. Since the name itself is uninformative, open the document and confirm the title block shows the same board number and revision as your PCB before relying on it.
