<P> Most WoL hardware functionally is typically blocked by default and needs to be enabled in using the system BIOS . Further configuration from the OS is required in some cases, for example, via Device Manager network card properties on Windows Operating systems . More below . </P> <P> Modern versions of Microsoft Windows integrate WoL functionality into the Device Manager . This is available in the Power Management tab of each network device's driver properties . For full support of a device's WoL capabilities (such as the ability to wake from an ACPI S5 power off state), installation of the full driver suite from the network device manufacturer may be necessary, rather than the bare driver provided by Microsoft or the computer manufacturer . In most cases correct BIOS configuration is also required for WoL to function . </P> <P> The ability to wake from a hybrid shutdown state (S4) or a fully powered off state (S5) is unsupported in Windows 8 and above, and Windows Server 2012 and above . This is because of a change in the OS behavior which causes network adapters to be explicitly not armed for WOL when shutdown to these states occurs . WOL from a sleep state (S3) or non-hybrid hibernation state (S4) is supported . </P> <P> Modern Mac hardware supports WoL functionality when the computer is in a sleep state, but it is not possible to wake up a Mac computer from a powered - off state . </P>
