Catalogued as a schematic, this 61.8 KB PDF is identified only by the code 70u, with no laptop model, board number or revision stated. It is likely related to the larger 70u-d document in the same set, but the difference between them is not described by the names. The compact size points to a short reference sheet rather than a multi-page board schematic. Open it in any PDF reader, and make sure the device or component code on your hardware matches before trusting its values.
