Listed as a schematic, this PDF of 28.2 KB is named 3LP01M and carries nothing beyond that part-style code with an M suffix. No brand, laptop model or board number is mentioned. Expect a brief component reference with pin assignment, limits and package dimensions rather than a full board diagram. Technicians use such sheets to confirm which pin is which before probing, judge whether a part is suitable as a swap and cross-check a marking code. Make sure the suffix on the actual part matches this one.
