PDF document of 196 KB identified only by the part number 2SA2058. Under the Japanese JIS convention, 2SA parts are PNP bipolar transistors, so this is almost certainly…

Datasheet-style PDF for the 2SA1241, 279 KB in size and filed among schematics. Nothing else is given in the name, so expect the usual electrical characteristics rather…

The 2SA1930 is covered in this 190 KB PDF, which carries no detail besides the part number and is probably the component datasheet rather than a schematic.

Small 41.8 KB PDF for the 2SA1890, with an _E suffix in the name that commonly marks an English-language edition of a Japanese datasheet, though the file does not…

PDF document of 47.8 KB listed as a schematic and named 2PC1815, issue 3 by the trailing number.

Compact PDF, 45.7 KB, named 2N2102 and catalogued under schematics. The 2N prefix belongs to the JEDEC scheme for discrete semiconductor parts, so the document is most…

Datasheet-style PDF for the JEDEC part number 2N7224, 64.1 KB, catalogued as a schematic.

A 177 KB PDF for the JEDEC part 2N5655, carrying an RE suffix whose meaning the name does not explain.

Listed under schematics, this 188 KB PDF is named for the JEDEC part 2N5550 with an RE suffix whose meaning is unclear. No laptop, board code or revision is given.

2N5400 transistor datasheet marked Sam, a 56.9 KB PDF that probably originates from Samsung, although the name alone cannot prove it.

PDF document of 238 KB covering the 2N4398 device, with an RE suffix in the name whose meaning is not stated, possibly a reissued or revised sheet.

A 46.1 KB PDF datasheet covering the 2N3019 transistor, indexed in the schematic category.

Catalogued as a schematic, 1T407 is a compact PDF of 52.9 KB whose name contains only a component code. No device model, brand or board number is given.

A small PDF of 69.9 KB, listed under schematics and titled with the part number 1SV268.

A 67.7 KB PDF reference for the 1SS395, recorded as a schematic in the index. The 1SS prefix is the Japanese JIS-style designation for small-signal diodes, so the…

A 98.0 KB PDF for the 1SS390, the largest of this group and filed as a schematic type. The name holds only the part number.

Larger than most of its neighbours at 123 KB, this PDF is named only 1SS313 and gives no device or board details.

Nothing beyond the code 1SS309 appears in the name of this 69.5 KB PDF, so no device or board can be tied to 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.

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.

A small PDF of 147 KB catalogued as a schematic, although the name 1N3288A follows the JEDEC 1N registration used for discrete diodes, so it is most likely a component…

Listed as a schematic, this 145 KB PDF carries only the code 150ebu02 and names no device, board number or revision.

Catalogued as a schematic, this 51.9 KB PDF is named only 130hf, which tells little about its content: no device, board number or revision is stated.

Named 5EQ100 and catalogued as a schematic, this 74.2 KB PDF gives no device model, board number or revision.

A 110 KB PDF titled 4GBU series, filed under schematics without any board number, revision or device.

Catalogued as a schematic, this 47.5 KB PDF is labelled only as the 2KBP series, a designation that reads like a discrete semiconductor part family rather than a laptop…

The 1SR156-400 document is a 120 KB PDF catalogued as a schematic, though its name follows a discrete component part-number style and carries no device or board…

Indexed as a schematic, the 104mtkb document is a 159 KB PDF whose name follows a power semiconductor series style with no voltage suffix, device model, board number or…

A short 64.3 KB PDF titled after the 1KAB-E series, catalogued as a schematic but by its name more likely a datasheet covering a family of discrete components such as…

PDF of 541 KB named only with the number 75006379, with nothing in the name identifying the device, maker or part it describes.

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.

Indexed as a schematic, this 118 KB PDF carries only the number 271024, which most often points to a 27C1024-class 1 Mbit parallel EPROM datasheet, though the name alone…

Numbered 27512, this compact 97.8 KB PDF is listed as a schematic but names no brand, board or revision.

Catalogued as a schematic, this 143 KB PDF is named 87cnq020 and states no brand or device.

Listed under schematics, this 92.0 KB PDF has a purely numeric name, 27256, with no manufacturer or revision attached.

Named 2764a, this 99.2 KB PDF sits in the schematic category, with the trailing a likely marking a revised version of a 2764 part.

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…
