Vostro 3530 WOL

Why this Dell Vostro turning off powerr to NIC when is notebook turned off, hibernated or goes to basic sleep mode ? This does not support WOL ? NIC it supports, but is not possible wake notebook from sleep, hibernation ... In BIOS are a lot of stupid power options but not setting for WOL.

Technical support phone was very funny: "Wake-on-LAN does not work via USB adapter when the computer is turned off. (Power supply S5 - Soft shutdown - in standby mode.)"
