PDF linked to the ASUS GX502LXS, 1.82 MB, filed as a schematic even though BDV in the name points to boardview content.

RAR archive of about 12 MB labelled E510MA-BR979, which corresponds to an ASUS E510MA laptop configuration code, though the name does not say what files are inside.

Schematic PDF with an uninformative single-letter name, B, so neither the device, the brand nor the board number can be determined from the name.

Sony notebook schematic referencing the 915PM and GM chipset variants, the Intel Mobile 915 Express family, in a 1.17 MB PDF.

Quanta BLBD schematic, a 973 KB PDF. The name holds only this code, with no revision or laptop model, and the exact meaning of the BLBD suffix is not stated, so it could…

Generic ZIP archive of about 3.93 MB whose name, Archive (1), gives no information about the device or contents.

Decrypted PDF schematic for board V330, with the suffix 71 most likely marking revision 7.1.

Decrypted PDF schematic covering board V330 at the revision marked 60, which is probably 6.0.

Component datasheet, 738 KB in PDF format, whose file name holds just the code SDLS190 and no model or part designation.

The title SDLS185 is only a literature code, so this 452 KB PDF datasheet does not reveal its component from the name alone.

Compact datasheet for the SN7404N, the widely used TTL hex inverter, in a plastic DIP package indicated by the N suffix.

PDF with the Texas Instruments literature number SDLS113, a code from the range TI applies to its older 54/74 TTL logic datasheets.
