Yes, Wake-on-LAN (WoL) is a standard networking technology that allows you to remotely turn on or wake up a computer from a shutdown or sleep state.

For it to work, two main conditions must be met:

1. The WoL function must be enabled on the network card (NIC): This is usually done from the system BIOS or UEFI. It is necessary to access the BIOS/UEFI settings when starting the computer and look for an option related to “Power Management”, where you can find and activate Wake-on-LAN. Exact options may vary depending on your motherboard or computer manufacturer.
2. OS level configuration: In addition to enabling WoL in the BIOS/UEFI, in some cases it may be necessary to activate the feature from the operating system. This is done through device manager in Windows or through network settings in other operating systems, ensuring that the network card is configured to allow the device to wake up in response to a WoL “magic packet.”

The Wake-on-LAN process works by sending a “magic packet,” which is a specific network packet that contains the MAC address of the destination computer within its payload. This packet is usually sent over the local network, although there are also methods to send it over the Internet with the appropriate configuration.

Upon receiving the magic packet, if WoL is enabled and properly configured, the computer turns on as if the power button had been physically pressed.

It is important to note that for WoL to work, the computer must be connected to the power source and the network card must have power. In some cases, network cards have an indicator light that stays on when the computer is turned off, signaling that the network card is ready to receive a WoL magic packet.
