Motherboard schematic for the K42JV notebook, revision 2.0 as stated in the file name, supplied as a 2.44 MB PDF.

Document for the 3DD304X, stored as a 489 KB PDF and catalogued under schematics, though the name suggests a component datasheet.

Small 27.4 KB PDF named after the part code 5LN01C, indexed as a schematic though it reads like a discrete-component datasheet.

PDF of 77.6 KB named 2SD1620 and filed with schematics; the name carries nothing beyond the part number, which points to a component datasheet.

A 29.4 KB PDF for the 2SJ569LS, catalogued as a schematic though it is named in the style of a component datasheet.

Filed under schematics, the 143 KB PDF named 2SJ509 most probably holds the datasheet for a single transistor, since 2SJ in the Japanese JIS scheme designates a…

This 105 KB PDF is named after the 2SC4159 and, although stored as a schematic, should contain the specification sheet for that NPN bipolar transistor, as the JIS 2SC…

Part number 2SC4157 is the only clue in the name of this 125 KB PDF, which sits under schematics but is effectively a transistor datasheet.

A 463 KB PDF for the 2SC380TM, an NPN transistor numbered under the JIS 2SC scheme; TM is part of the name but its meaning is not explained.

Covering the 2SC5028, this 219 KB PDF is filed as a schematic yet is named like a component datasheet.

A 41.3 KB PDF named 2SC5018 with an additional _E suffix that the name does not explain.

Catalogued as a schematic, this 87.6 KB PDF is named only with the part number 2SC3808, which follows the Japanese JIS scheme where 2SC marks an NPN bipolar transistor…

Named for the 2SC2995, this 510 KB PDF is listed as a schematic but most likely holds the datasheet for a JIS-numbered NPN transistor, as the 2SC prefix indicates.

Listed among schematics, this 44.3 KB PDF is named after the 2SC2910, which under the JIS convention is an NPN bipolar transistor.

A 145 KB PDF filed under schematics and named only after the part number 2SC2814, so it is most likely the component's datasheet rather than a board diagram.

A 296 KB PDF identified only by the JEDEC-style part code 2N5769. The catalogue lists it as a schematic, yet the name points to a single discrete semiconductor, so its…

Filed as a schematic, 1SV231 is a 68.1 KB PDF named after a component code; the trailing underscore is not part of it.

Very small at 10.8 KB, this PDF named 1n6778 looks like a brief datasheet or spec page for a JEDEC 1N-numbered semiconductor, despite being indexed as a schematic.

Numerically named PDF, 75003177, of 289 KB, catalogued as a schematic but with no indication in the name of what part or device it covers.

Catalogued among schematics, this 115 KB PDF is named simply 403DMQ, with no suffix indicating a voltage variant and no device details.

PDF document of 112 KB, indexed as a schematic under the name 70u-d. The name gives no device, manufacturer or board number, and the suffix after the dash is not…

Labelled 30epf02, this 160 KB PDF is listed as a schematic but the name reads as a part number for a discrete power diode or rectifier.
