Because it is set either through the BIOS or through your network card’s firmware, you don’t need specific software to enable it. Your Ethernet or wireless card must also support this functionality. Your motherboard must be hooked up to an ATX-compatible power supply, as most computers in the past decade or so are. Wake-on-LAN is dependent on two things: your motherboard and your network card. , or keeps a file server or game server program available, should probably have the option enabled for the sake of convenience. This is useful if you plan to access your computer remotely for any reason: it allows you to retain access to your files and programs, while keeping the PC in a low-power state to save electricity (and of course, money).

The protocol also allows for a supplementary Wake-on-Wireless-LAN ability as well. The definition of “low power mode” has changed a bit over time, but we can take it to mean while the computer is “off” and has access to a power source. Wake-on-LAN (sometimes abbreviated WoL) is an industry standard protocol for waking computers up from a very low power mode remotely.
