Nokia 5120 schematic diagrams in a 432 KB PDF. Only the model name is provided, with no board number or revision.

Schematic diagram for the Samsung SGH-E700 mobile phone, a compact 294 KB PDF. The small size suggests a limited set of circuit sheets rather than a full service manual.

PDF of 310 KB, the largest in this group, named 2N1893 and filed as a schematic. The JEDEC 2N designation indicates a discrete semiconductor, so the content is probably…

The 1N486B is the subject of this 33.1 KB PDF, a datasheet for a JEDEC 1N-series diode even though it carries the schematic label.

Filed among schematics, this 61.3 KB PDF actually documents a single part, the JEDEC-registered 1N485B diode.

A small PDF of 48.8 KB indexed under schematics, whose name points to a 44-lead PLCC package, most likely a package outline or socket drawing rather than a full circuit…

The Microchip 24LC32A, a 32 Kbit I2C serial EEPROM, is documented in this 586 KB PDF that the index lists as a schematic, though it reads as a datasheet.

Schematic for the Sony VAIO PCG-NVR23 notebook, built on the MBX-67 mainboard; no revision is given in the name.

Quanta schematic shared by the HP Compaq nx9000, nx9030, nx9040 and Presario 2100, with board number 31KT7MB0067.

PDF schematic labelled LA-1761, a number that follows the Compal LA-series board naming, although the name omits the P suffix, the revision and the laptop model.

Schematic for the Compal LA-1302 laptop board at revision R1B, compressed into a 1008 KB RAR archive.

Circuit diagram for the Nokia 6150 phone, stored as a 431 KB PDF. No revision or board issue is stated in the name, so check the drawing against the actual PCB layout.

Schematic for the Lenovo 3000 G230, marked in the name as the DDR3 version, so the memory pages apply to boards using DDR3 rather than older RAM.

PDF covering the BUW84 and BUW85 transistors in a single 101 KB document, filed as a schematic.

Datasheet for the 2SA879 in a 49.9 KB PDF; the trailing _E in the name probably denotes an English version, though the name does not confirm it.
