Compact 65.6 KB PDF stored as a schematic and labelled 28LV64A, part of the 28LV64 low-voltage EEPROM naming family, with the A suffix indicating a specific variant.

Listed among schematics, 30BQ015 is a 105 KB PDF whose name corresponds to a part-number pattern, so the pages are expected to be a component datasheet.

PDF of 99.2 KB titled 25C64-128 and stored with schematics, apparently covering 25-series SPI serial EEPROMs in 64 and 128 Kbit densities.

A compact 77 KB PDF filed as a schematic, named 24WCXX, which refers generically to the Catalyst Semiconductor 24WC series of I2C serial EEPROMs; the name gives no…

PDF reference of 112 KB covering the 24LC01 and 24LC02 serial EEPROMs, 1 Kbit and 2 Kbit two-wire memories sharing a common pinout.

Named 20MT40KB, this 127 KB PDF is classed as a schematic, though the name does not identify any device, board number or revision.

Indexed under schematics, this 87.3 KB PDF carries the code 20ETS-FP and does not mention a laptop model, board number or revision.

A small PDF of 196 KB filed as a schematic, named after the code 20ETF02, which looks like a discrete semiconductor part number rather than a laptop board.

An 85 KB PDF named 10BQ100, catalogued as a schematic but following the part numbering of a surface-mount Schottky diode family in the International Rectifier and Vishay…

Schematic PDF, 2.13 MB, labelled only V6J. The short code looks like a model or project designation, but the name gives no brand, board number or revision.

Sony schematic named ms01, a 1.17 MB PDF; the code likely refers to a project or board, but the name gives no VAIO model or MBX number, so check the title block.

Lenovo IdeaPad Y510 schematic supplied as a 1.26 MB PDF. The name has no board number or revision, so identify the board from the title block and confirm that it matches…

PDF schematic for the K72JK motherboard, an ASUS-style model code, though the name gives no revision.
