Lenovo ThinkPad SL400 repair archive in RAR format, 824 KB in size. Apart from the model name, the title gives no board number, revision or content type. A separate discrete-graphics package exists for this model, so this one may cover the integrated-video board, though the name does not confirm that. Unpack it to inspect the files, which in such collections are usually schematics used for following rails and signals. Match the PCB board code before trusting any measurements or part references.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @schematicslaptop. Enginerys does not host this file.
