I have had a few boxes (old IBM Intellistations) that claimed to have this capability, but I don't recall ever enabling it because I didn't need it.

According to Wake-on-LAN - Wikipedia, the free encyclopedia there are a lot of variables to consider, but in at least some situations, all that is needed for wake-up is that the box be plugged into power, and receive the magic packet ... cheers, drl

It's not that simple. From the article you cited:

Quote:
In order for Wake-on-LAN to work, parts of the network interface need to stay on. This consumes standby power, much less than normal operating power. If Wake-on-LAN is not needed, disabling it may reduce power consumption slightly while the computer is switched off but still plugged in.
Plus, it has to be configured in the motherboard, BIOS, etc.
