At 377 KB this is the largest of a group of PDFs named after 1N part codes; this one is 1N1183, a JEDEC style diode designation, so it is most probably a datasheet even…

Labelled only 241NQ, this 45.4 KB-class PDF of 45.2 KB appears to be a series datasheet for a family of power rectifier devices, with no suffix pinning it to a single…

A short 147 KB PDF labelled only 93AA76, catalogued as a schematic but most likely an older datasheet for that Microwire serial EEPROM part.

Listed as a schematic, this 553 KB PDF named 29040a is most probably a datasheet revision for a 4 Mbit 29-series parallel flash part, the a suffix suggesting a later…

The name of this 237 KB PDF is just the number 2416, and it is filed as a schematic without any brand, model or revision.

Code 52CPQ030 is the only information in the name of this 69.9 KB PDF, which is filed under schematics. No laptop model or board number is mentioned.

PDF reference of 45.5 KB carrying the name 35scgq060, indexed under schematics. The code appears to be a component part number; no model, manufacturer or board revision…

The name 31DQ05 suggests a discrete diode part number, so this 75.9 KB PDF, although catalogued as a schematic, is probably a single-part datasheet.

Indexed under schematics, this 106 KB PDF is named only 30BQ060, a code that looks like a discrete component part number, so expect datasheet-style pages rather than a…

PDF of 96.4 KB labelled 30CTQ060L, a part-number style name that points to a component datasheet rather than a laptop or motherboard schematic.

PDF document, 103 KB, titled 30BQ040, a code that reads as a component part number rather than a motherboard number, so it should be treated as a datasheet despite the…

Datasheet-style PDF of 55.8 KB for the Catalyst 24WC256, a 256 Kbit two-wire serial EEPROM, even though the index lists it as a schematic.

Datasheet PDF of 121 KB for the 24C65, a 64 Kbit I2C serial EEPROM with smart features such as a high-endurance block and configurable write protection of memory…

A 75.1 KB PDF titled after the 24C16 part, with a _3 suffix that likely marks a third copy or revision of the same reference sheet.

PDF datasheet of 297 KB for the 24AA65, 24LC65 and 24C65 serial EEPROMs, a 64 Kbit I2C family.

Short PDF of 17.5 KB titled 23SC4428, catalogued under schematics. The name gives only a part number, and its 4428 suffix resembles that of a known smart-card memory…

A small 71.5 KB PDF with the very short name 16f, indexed as a schematic. The name is too terse to tell what device, series or component it covers, so the contents need…

Schematic PDF of 328 KB whose name, 8CLJQ045, reads like a component or part code and gives no laptop model, brand or board number.
