Only the part-like code 35scgq030 describes this 46.6 KB PDF, filed as a schematic. No laptop model, brand or board revision is indicated, so it is best treated as a component reference rather than a board diagram. A technician would consult it to identify terminals, confirm the case type and look up limits when replacing a failed part or checking whether an alternative is suitable. Open it in a PDF viewer and compare the exact marking on the device, because neighbouring suffixes in such series usually denote different grades.
