[SOLVED] DELL – Wake On Lan Not Working

Problem:

After enabling Wake on LAN the computer still fails to boot after the WOL ‘magic packet’ is sent.

When you check the network cable you notice that the LAN activity lights are both turned off.

dell-bios

Solution:

This issue occurs when the energy saving option is enabled in the BIOS.

For the Dell Optiplex 755 this is called ‘low power mode’ and must be ‘off’ for WOL to work.
