A small PDF filed as a schematic, named only 30FQ, which reads like a component part number rather than a board or laptop model. No brand, revision or device is stated, so the exact part has to be confirmed by opening the document. At 54.5 KB it is most likely a short datasheet or single-page reference. Technicians keep this kind of sheet to check pinout, ratings and markings before substituting a part. Compare the code printed on the component body with the document header before relying on any values.
