Schematic in PDF, 1.68 MB, for the SM6125 processor with an SM61 family tag; the phone model and board number are absent from the name.

Schematic archive catalogued under Samsung and named only A12, presumably the Galaxy A12 handset, though the name does not confirm the variant.

Schematic archive named only M33, with no brand given, a 940 KB ZIP. The name is too brief to identify the device reliably; it may be a phone model code, but that is not…

PDF of 536 KB for the Atmel AT93C46, a small serial EEPROM using the Microwire-style three-wire interface.

Document for the 2SK1448 semiconductor, a 109 KB PDF placed in the schematic category. The name is just the part number, which under JIS rules marks an N-channel…

A brief 34.4 KB PDF describing the 2SK1267 N-channel MOSFET from the Japanese JIS 2SK numbering range.

Part reference for the 2SK242, saved as a 170 KB PDF in the schematic section. Japanese JIS designations beginning with 2SK belong to N-channel FETs, so the file is most…

Datasheet-style PDF named after the 2SJ342 and indexed as a schematic, 311 KB in size. The name itself identifies only the semiconductor type.

Covering the plain 2SC5261 without suffix, this 183 KB PDF is indexed as a schematic but concerns a single NPN bipolar transistor, as the JIS 2SC prefix indicates.

Datasheet PDF for the 2SC5229, 135 KB, kept in the schematic category of the index. Japanese JIS part numbering assigns 2SC to NPN bipolar transistors, which identifies…

Indexed under schematics, the 116 KB PDF named 2SC5155 refers to a discrete semiconductor rather than a whole board.

Short 88.9 KB PDF carrying the transistor number 2SC4217, filed among schematics. JEITA assigns the 2SC prefix to NPN bipolar transistors, so this should be a datasheet…

Datasheet-style PDF for the 2SC4105, 92.7 KB, catalogued as a schematic. Following the Japanese JIS designation system, 2SC marks an NPN bipolar transistor, and this…

Indexed as a schematic, this 33.2 KB PDF is named after 2SC5669, a Japanese-standard NPN bipolar transistor designation, which points to a datasheet for a single…

Datasheet-style PDF, 42.2 KB, for the 2SC3829 transistor, carrying an _E suffix whose meaning the name does not explain, possibly an edition or language tag.

PDF reference, about 124 KB, for the 2SC3776 transistor. The JIS 2SC prefix identifies an NPN bipolar part, so although the file is labelled a schematic it most likely…

A 41.1 KB PDF named for the 2SC3312 part, listed as a schematic yet in practice a component datasheet.

PDF file of 231 KB for the 2SA1586, catalogued as a schematic but named after one discrete semiconductor.

PDF documentation, 75.9 KB, for the 2SA1434 transistor. Under the JIS scheme the 2SA prefix denotes a PNP transistor, and no other variant, maker or package information…

Transistor datasheet for the 2SA2070 in PDF format, roughly 189 KB. The 2SA prefix places it in the JIS category of PNP transistors for high-frequency use.

Plain-named 2N3905 document in PDF format, 62.6 KB, catalogued with schematics but most likely a one-part datasheet.

This 47.8 KB PDF is labelled 1T379 and catalogued as a schematic. No device model, manufacturer or revision appears in the name.

Named after the code 129NQ135 and filed as a schematic, this 113 KB PDF gives no laptop model, board number or revision.

This 193 KB PDF, catalogued under schematics, is named 110cnq045a, which reads as a discrete power component code rather than a board identifier.

Listed as a schematic, the 229 KB PDF titled 1B21 carries only a short code and no model, brand or revision, so its subject must be confirmed by opening it.

Listed as a schematic, this 87.9 KB PDF carries the code 72cpq030 and nothing else: no brand, laptop model or board revision.

PDF of 102 KB, indexed as a schematic, with the name 60CTQ045 as its only identifier. No laptop model, board number or revision is included.

Filed as a schematic, the 294 KB PDF is named 45CKQ100 and gives no laptop model or board information.

Schematic-category PDF of 111 KB, named 20ETF08, with no laptop model, board number or revision mentioned.

The 155 KB PDF titled 15tq060 is listed under schematics, but the name corresponds to the International Rectifier and Vishay Schottky rectifier numbering style.

A 66.0 KB PDF named 15cgq100, classed as a schematic. The name follows the International Rectifier or Vishay convention for Schottky rectifier parts, which points to a…

A 199 KB PDF for the 8ETH03 part, listed as a schematic in the index. The name fits the International Rectifier and Vishay hyperfast rectifier coding, so expect a…

Schematic in PDF format for the X51C, carrying an extra T12C tag that probably identifies a board or project code, though the name does not say so. The file is 1.58 MB.

ZIP archive with a PDF schematic for a board coded IPISB-AB, 1.07 MB in size. No brand, revision or system model is stated.

PDF schematic named 45IIX, 1.12 MB, with no brand or board revision given. The token may refer to a motherboard or chipset family, but that cannot be confirmed from the…

PDF of 699 KB carrying the uninformative name null, so nothing about the device, brand or board can be learned without opening it.

PDF schematic of about 2.6 MB titled only Metro, which is probably a project code name; the name gives no brand, model or board number.

Quanta schematic for a project coded ZN5, in PDF format. The name gives neither the laptop brand nor the model, so identify the target machine by finding the ZN5 code on…

PDF schematic of 272 KB titled only 19A97, which reveals no model, brand or board number.

Schematic PDF for the ASUS X507 family, naming the X507UBR, X507UA and X507UV variants, with no revision or board number in the name.
