ZIP archive of 1.10 MB for the ASUS X550CC laptop motherboard. No revision is given in the name and the contents are not listed, so extract it to see whether it holds a schematic, boardview or firmware. Because X550CC boards exist in more than one revision, compare the rev printed on your PCB with whatever the archive contains. Schematic and layout material helps trace power rails and signals, locate components and test points, and find the cause of a short or a missing voltage.
