Boardview for the Speedy mainboard at revision 2.1, packed as a small RAR containing a .FZ layout file. The name gives no laptop brand, though the Speedy board appears in Lenovo IdeaPad Y510 machines built by ASUS. FZ files open in viewers such as OpenBoardView, BoardViewer or FlexBV and show component placement, pin nets and test points on both sides of the PCB. Use it with the schematic to find parts and measure rails quickly, after confirming the board revision silkscreen reads 2.1.
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.
