Wake-on-LAN (WoL) is an Ethernet or Token ring computer networking standard that allows a computer to be turned on or awakened by a network message.

https://en.wikipedia.org/wiki/Wake-on-LAN

Dell for example, Dell T100 and  T105 work just fine with wol. The key is that on bootup, when prompted, you have to do a Cntrl S to go into the bcom configuration screen, 

then set the WOL option to "Enabled". Also, you must allow the system to boot into the OS (windows in my case) and then perform a proper shut down. 

if you you just hold the power button down and kill the system or pull the power plug wol would not work

find out NIC mac address by:

ipconfig /all  #windows

or 

ifconfig  #linux

At Arduino Yun/compatible:

opkg update
opkg install etherwake
etherwake -i eth1 00:1d:09:2e:36:93

"00:1d:09:2e:36:93" is NIC mac address
