ASUS E202SA laptop schematic in PDF format, about 1.15 MB, listed without a board revision in its name. Small, low-cost notebooks like this often come in with charging or no-power faults, and the diagram lets you follow the charger IC, battery path and regulators, check enable and power-good signals, and identify the part shorting a rail. Any PDF viewer will open it. Verify the revision printed on the board matches before you rely on component values, test point locations or pin numbers taken from the drawing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @Motherboard_Repair_Guide. Enginerys does not host this file.
