Boardview for the Q551LN motherboard at revision 2.1, stored in .fz format at roughly 158 KB. The .fz format is common for Asus-sourced board layouts and opens in viewers such as FlexBV or OpenBoardView, some versions requiring the correct decryption key. The file lets a technician find components by designator, highlight nets, locate test points and narrow down shorts on power rails. Make sure the board revision printed on the PCB reads 2.1, since earlier or later layouts may shift parts.
