Archive named only N501VW, which points to the ASUS N501VW model series, though no brand, board number or revision is stated and contents are not described. At about 1.05 MB it may hold a schematic, a boardview or both. Material like this helps trace power rails, locate shorted parts and find test points when a laptop shows no power or no display. Unpack it and check which documents are included, then compare the board revision and part number on the PCB with those in the files.
