Windows 7In Windows 7, the default shutdown operation puts the system into the classic shutdown state (S5), and all devices are put into the lowest power state (D3). WOL from S5 is not officially supported in Windows 7. However, some network adapters can be left armed for waking if enough residual power is available. Therefore, waking from S5 is possible on some systems if enough residual power is supplied to the network adapter even though the system is in the S5 state and devices are in D3.
Windows 8, Windows 8.1 and Windows 10In Windows 8, 8.1 and Windows 10, 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, 8.1 and Windows 10.
To disable the S4 state in Windows 8, 8.1 and Windows 10, follow these steps.
Note We do not recommend that you disable the hybrid shutdown (S4) state.
- In Control Panel, open the Power Options item.
