Windows 8 and Windows 8.1
In Windows 8 and Windows 8.1, the default shutdown behavior puts the system into the hybrid shutdown state (S4), and all devices are put into D3. WOL from S4 or S5 is unsupported. Network adapters are explicitly not armed for WOL in either S5 or S4 cases because users expect zero power consumption and battery drain in the shutdown state. This behavior removes the possibility of invalid wake-ups when an explicit shutdown is requested. Therefore, WOL is supported only from sleep (S3) or hibernation (S4) states in Windows 8 and 8.1.
PS. Если не работает WOL, то смотреть настройки BIOS и отключить hybrid shutdown (S4) state, в статье написано как.
