Here is a compact 73.3 KB PDF whose name, 1SS250, identifies a discrete part instead of a board, so treat it as a component datasheet despite the schematic label.

A 50.3 KB datasheet PDF for the 1N748A, part of the JEDEC zener series spanning 1N746A through 1N759A, stored in the schematic section of the index.

Datasheet for the 1N746A, the first part of the JEDEC 1N746A to 1N759A zener series, supplied as a 50.3 KB PDF and labelled as a schematic in this catalogue.

The name 1n6766 identifies a JEDEC-registered semiconductor, and this 17.1 KB PDF is likely its short datasheet, even though the catalogue lists it under schematics.

Small 52.8 KB PDF filed under schematics with the code 70eps08 as its only identifier. No laptop brand, model, PCB number or revision appears in the name.

The name 35gq150 gives nothing more than what resembles a semiconductor part number; this 48.1 KB PDF is indexed under schematics with no device, brand or revision…

PDF, 223 KB, named 30CTQ035, which follows the numbering of a discrete semiconductor rather than a board design, pointing to a component datasheet in the schematic…

Boardview file in BRD format packed in a small ZIP of about 101 KB, identified only by the code LI6J.

Circuit schematic for the Lenovo IdeaPad Y470, a PDF of about 1.13 MB. Only the model is stated, so the ODM board code and revision must be read inside and checked…

IBM ThinkPad X61 schematic in PDF format, approximately 1.42 MB. The file name gives only the model, without a board number, revision or chipset detail, so check the…

Duplicate upload of a 111 KB ZIP archive for board 11324-1, same size as the other copy and carrying the same unexplained GR tag.

ZIP archive of 1.48 MB for the Apple logic board numbered 820-3536. The name states no revision or content type, so it could be a schematic, a boardview or a mix of…

Board package for code 5LXWL, revision suffix RH-11, stored as a 1.53 MB RAR archive. The name identifies only the board, not the document type, so whether a schematic…

Boardview file in .cad format for the Inventec board 6050A2992901, project Hedwig, revision A02 (A2), marked as a fixed version of the file.
