If you use remote desktop, remote control file-gain access to, or other server software, you may leave your computer on at home or work when you leave the homely house. This uses more power. Instead, you could simply remotely power on your PC whenever you need to use it. This takes advantage of Wake-on-LAN.
In spite of its name, it’s possible to set up Wake-on-LAN to enable you to send a “magic packets” that will wake some type of computer up online. To create this ongoing work, you’ll have to create Wake-On-LAN normally first. You’ll typically find this setting in a computer’s BIOS. Enter the BIOS and ensure the Wake-On-LAN option is enabled. If you don’t see this program in your BIOS, check the motherboard or computer manual to find out if it supports Wake-on-LAN.
The computer may not support Wake-on-LAN or WoL may continually be enabled without related options in the BIOS. You may also have to allow this option from within Windows, whether there’s a WoL option in your BIOS or not. Open the Windows Device Manager, locate your network device in the list, right-click it, and select Properties.
Click the Advanced tab, locate “Wake on magic packet” in the list, and allow it. To access this option, open the Control Panel, click Security and System, click Power Options, and click “Choose what the energy control keys do” in the sidebar. Click on the “Change settings that are currently unavailable” link at the top of the screen, scroll down, and uncheck “Start fast startup (suggested).” Your PC will start up a bit slower, but you’ll be able to use Wake-on-LAN. Wake-On-LAN uses UDP. Many utilities use ports 7 or 9, but you can use any port you prefer for this.
You’ll need to forward a UDP interface to all or any IP addresses behind your router – you can’t just forward to a specific IP address. The Wake-on-LAN packet must be forwarded to every device operating behind your router, and a device will only awaken if the info in the WoL packet matches it. To get this done, you’ll need to forward the port to the “broadcast address,” that will broadcast the packet to all or any computers on a network.

Access your router’s configuration page and find the port-forwarding display to configure this. Some routers might not allow you to ports to this IP forward, so you may need to key your router to let you do this another real way. You might look up information about forwarding Wake-on-LAN packets or forwarding packets to the broadcast address with your router.
You could also want to set up powerful DNS on your router. Even if your IP changes, you’ll be able to send a Wake-On-LAN packet to your router’s powerful DNS hostname and it’ll arrive at your computer. Having a constant hostname also makes it easier to remotely access services running on your computer.
