Restart your computer and enter the BIOS/UEFI setup. The method to access this menu varies by manufacturer, often involving pressing a specific key (like F2, Del, or Esc) during the boot process. Navigate to the Power Management or Advanced Settings tab.

Step 3: Enable Wake-on-LAN

Locate the Wake-on-LAN or Remote Wake-up settings within the Power Management options. Enable the feature by checking the appropriate boxes or selecting the 'On' option. You might need to choose the network interface card (NIC) that will be used for WoL.

Step 4: Configure Network Interface

Access your computer's network settings and ensure that the NIC configured for WoL is set to 'Promiscuous Mode' or 'Listen Only'. This setting allows the computer to receive and process the Magic Packet. You can usually find these settings in the network adapter properties or advanced network configuration.

Step 5: Obtain the MAC Address

The Magic Packet is addressed to a specific MAC (Media Access Control) address. You need to obtain the MAC address of the target computer. This can be done by checking the network adapter's properties in the device manager or using network scanning tools.

Step 6: Send the Magic Packet

Use a WoL-enabled network switch or a dedicated WoL software tool to send the Magic Packet to the target computer's MAC address. The computer should then wake up and resume its operation. Ensure that the target computer is powered off or in a sleeping state when sending the packet.

Remember, Wake-on-LAN is a powerful tool, and proper configuration is essential to avoid any unintended wake-ups. Always test and verify the settings in a controlled environment before deploying them in a production network.

Command Line: Utilize remote commands like `wakeonlan` to wake up the computer

To wake up a sleeping computer remotely using the command line, you can employ a technique called Wake-on-LAN (WoL). This method involves sending a specific network packet to the sleeping computer, which then triggers the system to wake up. Here's a step-by-step guide on how to achieve this:

First, ensure that your computer's BIOS/UEFI settings support Wake-on-LAN. This feature is typically found in the 'Power Management' or 'Advanced' settings. Enable the 'Wake on Magic Packet' or 'Wake on LAN' option to allow the computer to respond to remote wake signals.

Next, you'll need to identify the MAC address of the computer you want to wake up. The MAC address is a unique identifier assigned to network interfaces and can be found in the computer's network settings or by using a network scanning tool.

Now, open a terminal or command prompt on the computer from which you want to send the wake command. You can use the `wakeonlan` command, which is available on various operating systems. For example, on Linux, you can use the `wakeonlan` command followed by the MAC address. On Windows, you can use the `netsh` command with the appropriate parameters. The syntax might look something like this: `wakeonlan 00:11:22:33:44:55` (replace with the actual MAC address).

When you execute the command, the network interface card (NIC) on the sleeping computer will receive the wake signal and, if configured correctly, the computer will power on. This method is particularly useful for servers or network devices that need to be accessed remotely without physical interaction.

Remember that Wake-on-LAN requires proper network configuration and firewall settings to ensure the packets reach the target computer. It's also essential to test and verify the setup to ensure successful remote wake functionality.
