Zip archive of 308 KB named only for the Lenovo ThinkPad T60, with no board number, revision or file type mentioned. Its contents should be checked after extraction; it may contain a schematic, boardview or firmware material for that model. The T60 shipped with different mainboard variants, including integrated and discrete graphics versions, so match the board identification printed on your PCB against the documents before using them. Use the material to follow power sequencing, check suspect shorts and locate components during repair.
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 @ITHINKHS. Enginerys does not host this file.
