What triggers Wake-on-LAN?

Summary. The Wake on LAN (WOL) feature wakes a computer from a low-power state when a network adapter detects a WOL event. Typically, such an event is a specially constructed Ethernet packet.

Can Wake-on-LAN Turn on a computer that is off?

Overview. Wake-on-LAN (WOL) allows a computer to be powered on or awakened from standby, hibernate or shutdown from another device on a network. The process of WOL is the following: The target computer is in standby, hibernate or shutdown, with power reserved for the network card.

Does Wake-on-LAN always work?

WOL does not work when the system is running on battery. This is by design. Confirm that the link light remains on when the system is powered off. If there is no link light, then there is no way for the NIC to receive the magic packet to wake the system.
