Schematic covering the ASUS A42J and K42JR notebooks, a 2.30 MB PDF. Both model names appear in the file name, implying a shared mainboard design, but no board number or…

Section 6 of the GT-S7580 and GT-S7582 service documentation, a 273 KB PDF whose Direy label is unclear and may be a truncated chapter name such as disassembly and…

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.

Troubleshooting section of the service documentation for the Samsung GT-S7580 Galaxy Trend Plus, supplied as a 3.08 MB PDF; TSHOO is Samsung shorthand for…

Lenovo ThinkPad schematic for board NM-A151 in PDF form, 1.79 MB. The NM- numbering belongs to LCFC, the Lenovo ODM behind many ThinkPad boards.

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…

Schematic set for the HP nx900 laptop, distributed as a 1.01 MB PDF. The file name identifies only the model and provides no board number or revision, so confirm the…

Schematic in PDF format for a GTX 750 Ti graphics card, based on the board code P2010-B01, which follows NVIDIA's reference PCB numbering.

PDF titled only with the part number D304X, about 489 KB, filed as a schematic. The name gives no further detail on device type or manufacturer, so the contents are most…

The 2SD2648 is covered by this 29.0 KB PDF, indexed as a schematic but in practice a single-device reference.

PDF of 27.9 KB filed as a schematic under the code 3LN01S, which reads as a discrete component part number with an S suffix.

Named only 2sd1897, this 35.6 KB PDF is listed as a schematic, yet the name is a JIS transistor number, so it is very likely a compact datasheet.

Indexed as a schematic, this 112 KB PDF carries just the name 2SK1454, a JIS-style code for an N-channel field-effect transistor.

Listed as a schematic, this 246 KB PDF carries the name 2SJ201, a JIS part number for a P-channel FET, so it is best treated as a component datasheet.

Datasheet for the 2SD875 NPN transistor, supplied as a 43 KB PDF; the _E suffix in the name most likely marks an English-language edition, though this is not certain.

Short 125 KB PDF on the 2SC5086FT, the FT-suffixed variant of the 2SC5086 NPN transistor; the name does not say what the suffix means, though such suffixes usually mark…

Part number 2SC3805 is the only information in this 184 KB PDF name, and although it is listed as a schematic, the 2SC prefix under Japanese JIS numbering identifies an…

Component documentation for the 2SA1591, an 89.4 KB PDF. Only the part number appears in the name; no revision or manufacturer is given.

The 2SA1869 is covered by this 174 KB PDF, a PNP bipolar transistor in the Japanese JIS 2SA series.

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

Part code 1SV234 is the only detail in the name of this 65.8 KB PDF, which is filed as a schematic. No equipment model or board number is stated.

Labelled 1SS268, this 126 KB PDF appears to be a datasheet for a single component even though the index lists it as a schematic.

Two part numbers appear in the name, 1N914 and 1N916, so this 78.8 KB PDF is a shared datasheet for two related JEDEC 1N diodes rather than a board schematic.

Indexed as a schematic, the 180 KB PDF named 1G1-1G7 points to a numbered series of parts, most likely a rectifier diode family where the digits step through voltage…
