Boardview for the ASUS K52DR notebook mainboard, revision 2.2, packed as a 350 KB RAR archive. With it a technician can locate any component by designator, view the nets connected to each pin, and find test points while chasing a short or a missing power rail. After extraction, open the file in a boardview program such as OpenBoardView or FlexBV, depending on the format inside. Make sure the revision printed on the PCB is 2.2, because part placement can differ on other revisions of the same model.
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 @boardview. Enginerys does not host this file.
