Datasheet for the 1N4937GP diode, 45.7 KB PDF, indexed as a schematic. The GP suffix is typically used by manufacturers for glass-passivated construction.

A PDF of 129 KB indexed as a schematic, though the name 6CWQ03FN reads like a discrete semiconductor part number rather than a board number, so it is most likely a…

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

Catalogued as a schematic, this 155 KB PDF named 1F1-1F7 indicates a numbered component series, most plausibly rectifier diodes in steps of reverse voltage.

Named 93CXX and sized at 132 KB, this PDF is listed as a schematic but appears to be a generic datasheet for 93C-series Microwire serial EEPROMs.

Short PDF of 130 KB named 274002, a bare number that gives no device, brand or part information.

Catalogued under schematics, this 123 KB PDF is named 80CPT015, a part code in International Rectifier style that most likely refers to a Schottky rectifier datasheet…

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.

A short PDF of 53.5 KB, labelled 60CDQ and catalogued as a schematic. No product, brand, board revision or version appears in the name, so it should be opened in a…

Datasheet in PDF form, 162 KB, covering the 43CTQ080 part, catalogued here as a schematic.

A 148 KB PDF named 27lc512, filed under schematics but most likely a datasheet for a low-voltage 27-series EPROM, given how the part number is built.

PDF schematic, 950 KB, named only U6V. The name gives no brand, board number or revision, so confirm what it covers from the document title block.

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

PDF for the bq24780S, a Texas Instruments battery charge controller used in notebooks; though tagged as a schematic, the 1.03 MB file is most likely the datasheet.

PDF circuit diagram for the Quanta-made motherboard DAZ8EMB18A0, revision A, the final letter of the board code.

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