Lenovo schematics, boardviews and BIOS

The catalog lists 1,254 Lenovo boards with 5,090 files: 702 boards have schematics, 352 have boardview files and 1,016 have BIOS dumps.

Most Lenovo laptop boards are designed by ODMs. IdeaPad, Legion and many ThinkPad boards carry LCFC NM-xxxx numbers; older models use Compal LA-xxxxP, Wistron or Quanta codes. The code is printed in the PCB silkscreen, and a separate sticker carries Lenovo's FRU part number.

Search by the silkscreen code rather than the FRU number: one laptop model can ship with several boards (integrated or discrete graphics, different CPUs), and each has its own FRU but shares the ODM code with sister models.

In this catalog most Lenovo boards are identified by LCFC NM-xxxx, Compal LA-xxxxP and Wistron project numbers. Search by the code printed on your PCB if you are not sure which board your laptop has.
