Component document in PDF form, 47 KB, named 2PA1774 with a suffix 2 that likely denotes the sheet issue.

PDF of 47.9 KB filed as a schematic and named for the part 2PA733, revision 4 by its suffix.

Very small PDF, only 16.5 KB, named 2pg352 and catalogued under schematics. The name is terse and gives no device, brand or board number, so it most likely holds a one…

Brief PDF document of 25.6 KB named 2pg351, listed as a schematic. Apart from the part-like code, the name carries no model, brand or revision, so treat it as a short…

PDF of 25.8 KB carrying only the code 2pg302 in its name and filed under schematics. No laptop model, board number or manufacturer is stated, so the content cannot be…

Short PDF, 26.4 KB, named 2pg301 and placed in the schematic category alongside related 2pg files.

Component data in a 47.8 KB PDF named for 2PD1820A, with the suffix 2 likely marking a document revision.

PDF of 47.7 KB named 2PD602A, apparently issue 4 of the document. The name identifies a part rather than a product or board, which points to a discrete semiconductor…

Small PDF reference, 47.7 KB, for the part 2PD601A, with the trailing 4 most likely the sheet revision.

Data sheet sized PDF of 45.9 KB named 2PC4617J, revision 2 judging by the suffix. The J suffix normally separates a package or variant from the base 2PC4617 part, which…

PDF of 46.9 KB filed under schematics but named after the component 2PC4617, with a suffix 3 that likely denotes the document issue.
