Part number 2SB1209 with an _E suffix identifies this 42.6 KB PDF, filed under schematics though a single-part document of this kind is normally a datasheet.

Only the part code 2N5657 identifies this 497 KB PDF, which the index lists under schematics.

Titled simply 111ria, this 104 KB PDF is indexed as a schematic, though the name resembles a power semiconductor series code rather than a motherboard identifier.

Schematic in PDF format for a Pegatron board identified as C15B RG, packed in a RAR archive.

Second copy of the THL32C3D TV service document, a 16.2 MB PDF with a -1 suffix and the same size as the unsuffixed file, so it is most likely a duplicate.

Binary firmware image of 8.00 MB named DM10S140, a code that does not state the laptop model, brand or motherboard number.

PDF datasheet titled bq25a, 1.73 MB. The name is brief and does not identify the exact part, though the bq prefix is used by Texas Instruments for battery management and…

Compact 130 KB RAR archive named C5225 T, a name too terse to identify the device, brand or document type with certainty.

Small 128-byte binary named dell56, a size that matches one base EDID block for a laptop panel EEPROM; the name gives no model, panel or resolution.

PDF reference sheet for the 2SC3921, 30.7 KB, catalogued among schematics but named with a JIS transistor code.

The 2SA1564 is covered by this 90.3 KB PDF, which is labelled as a schematic but named after a discrete component.

This 67.6 KB PDF, sorted under schematics, identifies itself only as 1SS300, with no laptop or board stated.

PDF of 102 KB listed under schematics with the name 400U080D. The name provides no laptop model, board number or revision and reads like a semiconductor part number with…

Filed as a schematic, this 168 KB PDF is identified only by 20L15T. It gives no brand, model, board number or revision, so its exact subject is unclear from the name…

Zipped BIOS dump of 7.41 MB whose name suggests an unlocked or password-removed image, though no device, brand or board number is given.

Schematic PDF for a board identified as UL50AT, 1.23 MB in size. The name gives no revision or brand, so check the title block inside the document for the board version.
