Boardview file for the Quanta KT2 motherboard in .bv format, 840 KB. Boardview shows component placement, part outlines, net names and pin connections, so it helps locate test points, find every part on a shorted rail and check continuity between pins. The .bv format is opened with boardview software such as OpenBoardView or FlexBV, depending on the variant. No revision is stated, so compare the KT2 code on the PCB with the layout. Quanta makes boards for many laptop brands under codes like this.
