Boardview for the Quanta MA2 notebook motherboard, packed in a 140 KB RAR archive. The name does not reveal the board revision or the format of the file inside, so extract it first and open it in a boardview program such as OpenBoardView or FlexBV. A boardview shows component placement, part references, net names and test points on both sides of the PCB, making it easy to find a part named in the schematic. Pair it with an MA2 schematic of the same revision, and check that your board number matches before you probe.
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 @smschematics. Enginerys does not host this file.
