ASUS UL80V mainboard boardview, MB revision 2.0, in BDV format inside a 146 KB RAR archive. A boardview places every component and net of the PCB on screen, which helps locate parts by reference, find test points, and follow a rail from the charger to the load when diagnosing shorts or no-power faults. It opens in OpenBoardView, FlexBV and similar viewers. Another file for the same board and revision exists, so compare the two if one seems incomplete, and confirm the revision on the PCB first.
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 @pkbiosbdv. Enginerys does not host this file.
