Small 40.7 KB PDF named 2SC2925 with an added _E suffix, classified here as a schematic.

Component datasheet for the 2SB1434 transistor, filed under schematics but in practice a part reference rather than a board diagram.

Component data in a 47.8 KB PDF named for 2PD1820A, with the suffix 2 likely marking a document revision.

Component PDF for the 1SS391, 69.0 KB, stored with the schematics. The filename carries only the part number and an underscore, so there is no laptop model, board…

Datasheet in PDF, about 91 KB, for the 93C66 serial EEPROM, the 4 Kbit member of the widely used 93-series Microwire family; the _3 suffix in the name likely marks a…

Short 77.9 KB PDF in the schematic section, named only 22CGQ045, with no brand, model or board revision given.
