PDF schematic for a Z96Fm board, revision 1.0, about 4.6 MB in size. The name gives no laptop brand or model, so confirm the target from the title page and from the code printed on the PCB. Revision 1.0 drawings can differ from later revisions, so check the revision matches before trusting values or reference designators. A technician uses this to follow the power path, check enable and power good sequences, and locate the components around a shorted rail or a failed supply controller.
