How to wake the system up

First, you should check if all Settings are done correctly. Shut down the system and check if the Network LEDs are still on. If so the settings are fine and you can use WoL.

In this example, we will use the wol.exe, but you are free to use any of the plenty Wake on Lan tools available.

Note: Dell does not endorse this Software and using it is at your own risk.

Please choose the Wake on Lan tool that suits your needs and download it. You should be able to find plenty of them in a Websearch like Bing or Google
