Which Dell Computers and Notebooks have complete WOL support?

WOL = Wake On LAN

Complete = Remote Start from complete shutdown and not just standby.

Also which of them are PCI 2.1 vs 2.2. 2.1 needs a connector on the motherboard, 2.2 does not!

Be careful, some/many systems have bios that may make you think it supports but it does not!
