Archive for the ASUS A46CB and K46CM main board at revision 2.0, a 3.61 MB RAR. The name does not say whether it holds a schematic, boardview or firmware, so open it to check the contents. These models share one mainboard design, which is why both names appear. Material like this helps a technician trace power rails, find test points and work through no-power or no-display faults. Confirm that the board on the bench is labelled revision 2.0 before relying on part locations or values.
