RAR archive of 2.83 MB labelled as Lenovo W541 temp2, apparently a second temporary or working dump set from a ThinkPad W541. The name does not list board number, chip or contents, so open it and inspect what the archive actually holds before relying on it. Files of this size commonly hold an SPI BIOS image or related service data. Match the PCB board number and revision with the source, and read and save the original flash chip with a programmer before writing any image from it.
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 @SCHEMATICWORLD. Enginerys does not host this file.
