The code 35C804A is all the name provides for this 173 KB PDF, which is catalogued as a schematic. It does not mention a laptop model, brand or board revision, and its meaning cannot be confirmed from the name alone; it may be a part or document reference. Open it in any PDF reader and inspect the title block or header to see what device or component it covers. Before using it for tracing rails or identifying parts, make sure the numbers printed on your hardware correspond to what the document describes.
