Boardview of the ASUS UL80V mainboard, revision R3.0, BDV format, packed as a 149 KB RAR file. It covers the later PCB revision, so placement and some nets may differ from the 2.0 version also in circulation. Technicians use it to find components, follow power and signal nets, and pick test points while chasing shorts or missing voltages. Open it with OpenBoardView, FlexBV or another BDV-capable viewer, and make sure the silkscreen on your board really reads 3.0.
