ASUS X553MA laptop schematic, a PDF of around 1.17 MB; the RG suffix in the name is not explained and may mark a board revision or variant. With it you can follow the supply rails from the DC jack to the processor and memory, check the power-on sequence and identify components around a short or burnt area. Open it in any PDF reader. Before relying on part values, compare the revision printed on the mainboard with the one in the schematic title block.
