Repair guide for the ASUS K43L notebook, delivered as a 554 KB PDF with photos, catalogued here under schematics.

PDF document of 577 KB for the AD620, filed in the schematic category although a part-number name like this normally indicates a component datasheet.

A 53.4 KB PDF covering the 2SD2614 transistor, catalogued as a schematic although the name points to a single-part datasheet.

The smallest of this group at 26.5 KB, this PDF carries the code 3LN01SS, resembling a discrete semiconductor part number with an SS suffix, and is catalogued as a…

Datasheet-style PDF of 139 KB for the 2SK2460N, listed in the schematic category. Under Japanese JIS numbering a 2SK prefix marks an N-channel field-effect transistor…

Listed under schematics, this 94.5 KB PDF carries only the designation 2SJ276. Under the JIS system the 2SJ prefix belongs to P-channel FETs, so the file is almost…

Small 53.0 KB PDF for the 2SD1280 with an _E suffix, classified as a schematic in the index.

PDF document for the 2SD1205 transistor, listed in the index as a schematic but almost certainly a part datasheet; the trailing _E in the name is a suffix whose meaning…

Indexed as a schematic, this 55.8 KB PDF actually names a discrete part, the 2SC3930, followed by an _E suffix.

Named after the 2SC1383, this 51.4 KB PDF is listed as a schematic, yet the JIS prefix 2SC denotes an NPN bipolar transistor, so expect a part datasheet.

A 58.1 KB PDF labelled as a schematic and named after the 2SC1215, an NPN transistor by Japanese JIS naming, so it should be the datasheet for that discrete part.

Datasheet for the 2sb1566 PNP bipolar transistor in a 37.5 KB PDF. The 2SB label, per the JIS convention, means a PNP device for low-frequency circuits; the file name…

Filed as a schematic, the 51.8 KB PDF for the 2SA1534 carries an _E suffix in its name whose meaning is not stated; the content is most likely the datasheet for this JIS…

Small 81.5 KB PDF named after the 2SA1724 part number and filed under schematics. Nothing else in the name identifies a product or circuit board.

PDF reference of 51.6 KB named 2N1613, placed in the schematic category. The 2N prefix follows the JEDEC numbering used for discrete semiconductors, so the content is…

Small 20.5 KB PDF named for 2N5551 with a UTC tag, which most likely refers to the manufacturer that published this version.

Part number 1T409 is the only information in the name of this 49.5 KB PDF, which is catalogued as a schematic.

The file is a 56.2 KB PDF listed under schematics and labelled 1T408, with nothing else in the name to tie it to a specific product or board.

Only the part number 1SS374 is given in the name of this 68.5 KB PDF, so treat it as a component specification rather than a board schematic.

Part number 1SS345 is the only information in this 58.3 KB PDF name, so no laptop, board or revision is identified.

Component datasheet for the 1N457, a JEDEC 1N-series diode, saved as a 62.5 KB PDF and categorised here as a schematic.
