Motherboard ASUS P5Q PRO. It is adjusted WOL (wake on lan). The system unit and columns are connected to network filter Sven, at which at each socket the cutout. Columns for the night are ungeared by the cutout on the filter as the transformer of columns, most likely, buzzs. On the computer - Windows 7 x64, it is permanently used a mode "dream" (sleep, not hibernate), and so - it is frequent after computer leaving in a dream, after click of the cutout of the filter on a column, the computer clears up. Somebody can explain physics of process?. Well the wol-package in the twisted pair going to network port is not generated.
