Wake on LAN
In BIOS on the Power Management Setup: I have enabled Resume on PME Enabled. Again, in NIC cards' property in the power management section: I have enabled allow this device to wake the computer and only allow management station to wake the computer. But I even don't know why there in blinking light in nic card even the computer is off. and I don't see there is no option as Wake On Lan in BIOS. Any one can help me to setup WOL? or My computer doesn't support WOL? Should I connect some wires from motherboard to NIC inside my computer? My computer is Lenovo.

Thanks. We'll let you know when a new response is added.

Wake on LAN has several components that must be present in your system to work.

1. The power supply must be of a type that provides standby power. A power supply of the ATX standard provides standby power.
2. The motherboard must support WoL.
3. The network card must support WoL
4. The network card must receive standby power, either through the PCI connection or a separate power connection. The separate power connector is often from the motherboard (been a while since I’ve seen one).
5. Enabled in BIOS.

Most current systems meet all of these requirements (using the onboard NIC). It is older systems where you need to check compatibility of all components.

Oh, and turning the system off at the surge suppressor stops all of it from working. ;-)
