RAR holding two BIOS images, 32 MB and 16 MB, for the Quanta board DA0Y0PMBAE0, revision E, marked working.

A 43.9 KB PDF for the 2SD2580, indexed as a schematic. Japanese JIS numbering reserves the 2SD prefix for NPN bipolar transistors in low-frequency applications, so this…

Covering the 2SK2991, this 420 KB PDF is named only by part number, which points to an N-channel field-effect transistor in the Japanese JIS numbering system.

A 191 KB PDF describing the 2SC4604 transistor, categorised as a schematic though its content is almost certainly a manufacturer datasheet.

Datasheet in PDF format, 90.9 KB, for the 2SC4522 NPN bipolar transistor, the 2SC prefix being the JIS designation for that device class.

Datasheet for the 2SC4480, stored as a 99.8 KB PDF that opens in any standard reader. By JIS convention the 2SC prefix denotes an NPN bipolar transistor; the name gives…

The name of this 160 KB PDF gives only 2SC5738, and the index files it under schematics.

This 216 KB PDF documents the 2SC5463, a 2SC-series part, which under Japanese JIS designation is an NPN bipolar transistor.

Part 2SC5443 is the only detail this 42.3 KB PDF name provides. The 2SC prefix marks a JIS-registered NPN bipolar transistor, so expect a datasheet with electrical…

Covering the 2SC3953 transistor, this 40.7 KB PDF is catalogued as a schematic, though a JIS part-number name like this normally denotes a datasheet.

Specification PDF, 74.8 KB, for the 2SC3770 transistor. The 2SC code is the Japanese JIS designation for NPN bipolar transistors, so the content is component data, not a…

File for the 2SC2703, a 173 KB PDF listed under schematics, whose name only states the part number.

An 87 KB PDF for the 2SC2412K, an NPN transistor named under the Japanese JIS convention with a K suffix.

The 2SA1435 is the subject of this 29.8 KB PDF, and the file name gives nothing beyond the part number.

Datasheet for the 2SA1801 transistor in PDF format, roughly 123 KB. JIS part numbering uses the 2SA prefix for PNP bipolar transistors, so the sheet should contain…

Catalogued as a schematic, this 55.3 KB PDF is named 62cnq030, with no laptop model, PCB number or revision given.

Boardview for the LA5892 board, packed as a 305 KB RAR. BDV here means boardview. The code resembles Compal LA numbering, although no suffix or scheme is confirmed in…

Boardview file in .fz format for the K46CM motherboard, with r20 indicating revision 2.0.

PDF schematic packed in a 1.99 MB RAR for a board coded IPIMB-PV, with no brand, model or revision in the name.

RAR-compressed schematic for the Huawei MateBook X notebook, without a board number or revision in its name.

Zipped boardview for Quanta motherboard DA0V07MBAD1, with the name adding revision D and the project name Cynthia. Quanta uses the DA prefix followed by a project code.

Zip archive of 12.6 MB with an uninformative name that reveals nothing about the device, board or contents.

Schematic PDF for a Lenovo mainboard coded NM-A931, the numbering style used by LCFC, Lenovo's own design and manufacturing arm.

ZIP archive of about 6.24 MB labelled UC6, a short code that does not state the manufacturer, model or document type.

BIOS image named G6IC, a 4 MB binary for a 32-megabit SPI flash chip. The cryptic label states no brand, motherboard number, chipset or firmware version, so the source…

An 8.00 MB BIOS dump for a 450 G1 marked GRAPHICS, without file extension, apparently meant for the variant fitted with separate graphics; no brand, GPU type or…

A 16 MB image labelled 128kb 840 g2, apparently for an HP EliteBook 840 G2; no board number or revision is included, and the 128kb token is unclear, though the size…

Schematic in PDF for the Xiaomi Poco X3 Pro smartphone, 4.12 MB. The name gives no board revision or variant, so compare markings on the PCB with the drawings.

RAR archive of 4.13 MB for the ASUS A7S laptop, named only by model with no type or revision.
