ZIP archive of 79.3 MB for an ASUS K501UX laptop board, revision 2.0 as stated in the name. The contents are not listed, but a package this large commonly bundles a schematic, boardview and possibly a BIOS dump, so extract it and check each file. Schematics help trace power rails and signals, boardviews locate parts and test points, and a firmware image can be written to the SPI chip with a programmer. Verify the revision printed on the PCB is 2.0 before relying on the material.
