Schematic for the HP Evo 620 notebook, delivered as a 1.32 MB PDF. The name provides only the model, with no motherboard number, ODM project or revision, so check the…

Reference sheet for the 2SC2330, which the name marks as an NPN transistor, stored as a 431 KB PDF and filed under schematics.

PDF sheet of roughly 41.8 KB for the 5LP02M part, filed under schematics. Only the part number is given; by the series pattern the LP letters likely signify a P-channel…

Part reference sheet for 5HN01C, a compact 26 KB PDF listed under schematics. No laptop model or board number appears in the name.

Datasheet PDF for the 2SK2889, 417 KB in size and indexed here under schematics. The name states nothing beyond the part number.

PDF file of 314 KB for the 2SK2776, indexed under schematics. Since the 2SK prefix designates an N-channel field-effect transistor in the Japanese JIS system, the…

Covering the 2SK2733, this 413 KB PDF sits among schematics but is most likely the device datasheet, since 2SK is the Japanese JIS prefix for N-channel field-effect…

Datasheet-style PDF for the 2SK2608, sized 413 KB and catalogued under schematics. Under the Japanese JIS naming system, 2SK denotes an N-channel field-effect…

A 407 KB PDF for the 2SK2602, a part number following the Japanese JIS convention in which 2SK designates an N-channel field-effect transistor.

Listed among schematics, this 31.7 KB PDF refers to the 2SK2340, a Japanese JIS-numbered device where 2SK designates an N-channel field-effect transistor.

At 287 KB this PDF for the 2SK1875 is larger than its neighbours, which may mean extra graphs or pages, though the name says nothing more than the part number.

PDF document for the 2SK1530, filed under schematics although the name is only a semiconductor part number.

Part reference sheet in PDF form for the 2SK663, carrying a 2SK prefix that under the Japanese JIS system denotes an N-channel FET.

Covering the 2SK443, this 95.2 KB PDF sits under schematics, though the JIS 2SK naming for N-channel field-effect transistors indicates a component datasheet.

Here the only information in the name is 2SJ525, a Japanese-standard part code where 2SJ marks a P-channel field-effect transistor.

A 110 KB PDF labelled 2SJ440 and listed under schematics. The 2SJ prefix is the Japanese JIS code for P-channel field-effect transistors, so the content is likely a…
