Sleep unattended idle timeout

Specifies the duration of inactivity before the system automatically enters sleep after waking from sleep in an unattended state.

For example, if the system wakes from sleep because of a timed event or a wake on LAN (WoL) event, the sleep unattended idle timeout value will be used instead of the sleep idle timeout value.
