Archive in RAR format for the ASUS X550WE laptop board at revision 2.0, about 1.23 MB in size. The name does not say what is packed inside, so open it with 7-Zip or WinRAR to see whether it holds a schematic, a boardview or both. Material like this helps a technician follow power rails from the charger to the CPU and GPU regulators, find fuses and test points, and isolate shorted components. A separate 1.3 revision of the same model exists, so check the revision printed on your PCB before using any reference values.
