Waking up your computer from a distance is not only convenient but also a small technological marvel. Wake On LAN (WOL) achieves this task by listening for a “magic packet” that activates the system out of its low-power slumber. To harness this capability, a few configurations are necessary, starting with a dive into the UEFI firmware settings.
1. Configure UEFI Firmware Settings to Enable Wake-on-LAN
To awaken your computer with WOL, you must first ensure that the feature is activated in the BIOS or UEFI settings. Typically found under networking or power options, this setting allows the Ethernet network adapter to respond to WOL requests. The process to access these settings usually involves restarting your computer and pressing a dedicated key to enter the BIOS/UEFI setup.
2. Configure Wake on LAN Settings for the Ethernet Adapter
After enabling WOL in the BIOS/UEFI, make your way to the Windows Device Manager to tweak the Ethernet adapter settings. Look for the “Wake on Magic Packet” setting under the adapter’s properties and make sure it is turned on. Additionally, in the Power Management tab, confirm that the device can wake the computer and that it only responds to magic packets.
3. Disable Fast Startup
Fast Startup is a feature that saves a snapshot of your PC’s system files and drivers to a hibernation file upon shutdown, allowing for a faster boot time. However, this may interfere with WOL. Disabling Fast Startup through the Control Panel’s Power Options ensures that the Ethernet adapter remains alert for the magic packet even when the PC is powered off.
4. Wake Up a Computer Remotely Using WakeMeOnLan
With the network adapter primed and ready, you need a tool to send the magic packet. The WakeMeOnLan utility by NirSoft is a straightforward option. After downloading and running the program, it scans your network, listing all devices. Select your target computer from this list and initiate the wake-up command.
5. Create the On/Off Shortcuts
For those who prefer a quick desktop solution, create a shortcut to WakeMeOnLan’s executable, appending the command to wake your specific computer. Conversely, you can make another shortcut to remotely shut down the PC using the built-in Windows “shutdown” command. This way, you can manage your computer’s power state without moving an inch.
Being able to power up or shut down your computer remotely is a feature that can blend seamlessly into your daily routine. With just a few initial configurations and the help of a small utility, your PC is never more than a double-click away from being ready for action, no matter where you are.
