An 8.00 MB binary named lcd1, an uninformative name that gives no brand, model or board number; the lcd label may be a note about a display-related fix but cannot be…

Archive labelled only Quanta ZRL, a 1.24 MB RAR with no laptop brand, revision or file type in the name. ZRL appears to be a Quanta project code.

Small 330 KB RAR archive named for BoardViewR4 with a BRD reference, apparently a boardview viewer build or related tool for BRD-format files.

RAR archive of 1.14 MB for the IBM ThinkPad T60. Only the model is named, with no board number, revision or note on contents, so extract it and confirm what is included.

Firmware file labelled for several related Acer models: Aspire 1680, TravelMate 4003LCi and TravelMate 2303, international (INTL) version.

Datasheet for the classic Microchip PIC16C84, an early 18-pin microcontroller with electrically erasable program memory, delivered as a 961 KB PDF.

Summary datasheet for the ATmega406 AVR microcontroller, a 179 KB PDF. The ATmega406 is aimed at smart battery management, so this part often turns up inside laptop and…

Datasheet for the Maxim MAX691 microprocessor supervisory circuit, which combines power-on reset generation, a watchdog timer, battery backup switchover and memory write…

PDF of 126 KB covering the 2SD1842, an NPN bipolar transistor in the JIS 2SD series, so the content is a datasheet rather than a board schematic.

PDF of about 179 KB for the 2SD2531, filed as a schematic but probably the component datasheet.

A 107 KB PDF titled with the lowercase part number 2sd1565, catalogued as a schematic yet almost certainly a transistor datasheet.

Document for the 2SK2493 field-effect transistor in PDF form, 384 KB, listed under schematics in the catalogue.

Titled 2SK2378, this 26.7 KB PDF is the smallest in its series and is listed under schematics, but the JIS part number indicates a datasheet for an N-channel FET.

A 109 KB PDF for the 2SK1439, filed with schematics but most likely the manufacturer's data sheet for this transistor. The JIS 2SK prefix denotes an N-channel FET.

PDF for the 2SK1238, a Japanese 2SK-series N-channel MOSFET, size 45.9 KB. No manufacturer, package or revision appears in the file name, so match the printed marking on…

PDF datasheet for the 2SD1133, 43.0 KB, listed among schematics though its name refers only to the part.

Compact 27.2 KB PDF on the 2SC5291. The 2SC prefix identifies an NPN bipolar transistor in the JIS system, so this is most likely a short manufacturer datasheet, filed…

A 35.0 KB PDF relating to the 2SC5270. The 2SC prefix denotes an NPN bipolar transistor in the Japanese JIS system, so the document is most probably a compact datasheet…

Here is the 106 KB datasheet-style PDF for 2SC4637, a JIS-numbered NPN bipolar transistor.

This 28.6 KB PDF carries the part number 2SC4635LS, apparently a package or lead-form variant of the 2SC4635 NPN transistor.

Here is a 178 KB PDF for the 2SC5254, a Japanese JIS-registered NPN bipolar transistor, most probably its datasheet.

2SC4579 datasheet candidate in PDF form, 102 KB, categorised as a schematic. The name follows the JIS convention in which 2SC denotes an NPN bipolar transistor for…

Here is a 297 KB PDF named 2SC5590, sorted under schematics but bearing only a component number, so it should be the datasheet for that part.

For the 2SC5450 there is a 41.0 KB PDF, filed as a schematic, most likely holding the datasheet of this NPN transistor from the Japanese 2SC family.

Listed as a schematic, this 118 KB PDF is named only 2SC4863 and is most likely a component datasheet.

The 2SC3901 transistor is documented in this 88.3 KB PDF. Following the JIS convention, the 2SC prefix denotes an NPN bipolar device, so the file is most plausibly its…

PDF of 214 KB for the 2SC3328, an NPN bipolar transistor under the JIS naming system, catalogued here as a schematic though the content is likely a datasheet.
