Hehe... I remember back when I worked in polytechnic.
I had a bunch of computers with nics, connecting the wol cable and plugging the power in caused the psu to explode

I broke at least three psus before I figured it was that...
Now, when one of the computer we have at my current job got wol set on, it was unable to shutdown. You would shut it down, and it would spring to life within 5 seconds

WOL is something I don't want
