PDF schematic for the HP nx6320 laptop, around 1 MB in size. The name gives no motherboard number or revision, so compare the board identifier printed on the PCB before…

Quanta UT8A motherboard schematic in PDF form, about 1.14 MB. The name gives the Quanta project code UT8A but not the laptop brand or a board revision.

Schematic PDF named only CD731a, about 526 KB, with no brand, model or revision information in the name.

Schematic diagram for the Samsung NP-R423 laptop, supplied as a PDF of about 1.1 MB. Apart from the model, the name carries no board code name or revision, so confirm…

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

Reference PDF for the HCF4050B, a non-inverting hex buffer from the CMOS 4000 family, as the file name itself states.

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.

Filed as a schematic, the 28.3 KB PDF 3LN02SP is named after what appears to be a discrete component code, here from the LN series with an SP suffix.

PDF of 41.6 KB, catalogued as a schematic and named 3LN02M, which looks like a semiconductor part number with an M suffix rather than a board code.

Although filed as a schematic, this 37.9 KB PDF is named after 2SD2460 with an extra E tag the name does not explain.

The 2SD1908 transistor is documented in this 85.8 KB PDF, which the index files as a schematic, although a JIS part number like this normally indicates a datasheet.

Datasheet PDF of 413 KB for the 2SK2866 transistor, catalogued under the schematic type. Only the part number is stated in the name.

PDF of 140 KB for the 2SK2739 with an unexplained 1-5 suffix, which may indicate an edition or page count rather than a different part.

A 116 KB PDF for the 2SK2731 bearing a 1-5 suffix that the name does not explain, perhaps an edition marker.

Compact 23.1 KB PDF named only with the part number 2SK2277. Because 2SK is the JIS prefix for N-channel FETs, the schematic category here most likely holds a short…

PDF reference, 35.6 KB, for the 2SK2276, a Japanese JIS-registered device where the 2SK prefix indicates an N-channel field-effect transistor.

Small 33.2 KB PDF covering the 2SK1478, written in lowercase in the original name. The 2SK prefix belongs to the Japanese semiconductor designation for N-channel…

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…

Bearing only the part code 2SJ264, this 101 KB PDF relates to a P-channel FET, as the JIS 2SJ prefix designates that transistor type.

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…

Datasheet-style PDF covering the 2SD1199, catalogued under schematics, with an _E suffix in the name that the file does not explain.

The 2SC4030 transistor is documented in this 119 KB PDF, which is listed in the schematic section.

A 40.9 KB PDF for the 2SC5303, a JIS-registered NPN transistor, catalogued here as a schematic although it reads as a part datasheet.

Part data for the 2SC3152 NPN transistor, stored as a 103 KB PDF in the schematic section.

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.

Listed among schematics, this 60.7 KB PDF refers to the 2SC1047, which under JIS numbering is an NPN bipolar transistor; the content is therefore most likely a part…

A compact 19.1 KB PDF for the 2SA1580, small enough that it is probably a one- or two-page summary sheet. No other details are present in the name.

At 41.7 KB, this PDF is labelled with the 2SA1532 part number plus an _E suffix and is indexed as a schematic, though a single-part file like this is normally a…

The 2SA1518 is the subject of this 30.2 KB PDF, which the index files as a schematic although the name suggests a component data sheet.
