activates the power supply and boots the computer. The advantage of
this method is that computers do not have to be switched on permanently
(which saves energy), but they can be activated via WOL.
Note
Support for WOL
Wake on LAN only works with more recent motherboards that
support this functionality in their BIOS. WOL-capable network
cards mostly contain chips in the Intel i82557 (EEpro100B), i82558
(EEPro100+), or i82559 series. Further information about this
is available from: http://support.intel.com/support/

Unfortunately, a lot of hardware does not have this functionality,
even though it is apparently WOL-capable. Unfortunately, there
is no alternative but to try the relevant steps.
Note

Before using WOL, enable an option in BIOS that is frequently labeled ‘On-
